Frequent criticisms of Android would doubtless evaporate if more customers knew ways to maximise the good factor about their Android handset. Listed below are some purposes, ideas and methods that I've discovered to actually enhance the usefulness of my Android phone.

Fortunately, there are a variety of tools for managing your battery life that may assist you squeeze the most from your Android phone's battery.

A few of the options of Android aren't needed on a constant basis. These include Bluetooth, WiFi and GPS. These options can quickly drain the phone battery if they are working continuously.

There is a widget you can add to your phone's desktop that lets you switch these options ON and OFF with a single touch. Many purposes have the flexibility to toggle these ON and OFF as properly so if an utility wants one in all these options, it can activate it.

Another frustrating side of managing your battery life on Android is that the default battery meter solely displays a coloration: inexperienced, yellow and red to point how much battery energy remains. This could make it more durable to gauge if an utility is draining your battery more quickly than normal. Battery Meter Lite is a free software that features a battery remaining notification. When this notification is enabled a battery icon with the percentage of battery remaining will seem in your notification area. This makes it a lot simpler to manage your battery life because you know precisely how much battery energy remains.

Handcent features a threaded interface to can assist you visually see the forwards and backwards dialog you are having through SMS. It additionally allows sending footage via MMS and saving MMS attachments. You presumably can set Handcent because the default messaging utility on Android. Handcent will even present notifications for brand new SMS messages. The notification might be personalized a bit, including what colour your cellphone LED should flash when you might have new messages. While you change to Handcent, you will have to enter the default messaging utility and switch off its notifications. Otherwise, you're going to get two notifications each time you obtain a message.

Ditch Your iPod
Let's face it - carrying a phone and a music player is a pain. Luckily, you can simply change your iPod along with your Android phone. The default music player that ships with Android is agreeably nothing to put in writing home about. The interface may be very simple and albeit, fairly boring. However, you may simply exchange it with the Cubed Media Participant from the Android market.

Cubed is a free media participant with a considerably unique consumer interface. Album paintings appears in a third-dimensional cube. By rotating the cube up or down, you presumably can flick thru your album paintings in a fashion similar to iPod's cover flow.

We were happy that many of you liked the new look and interactivity of the app. However, we also heard your feedback about the app’s speed. Today we’re introducing changes that make the app more responsive as well as other visual changes that make search results even easier to read.

Faster app performance

This version of Google Search app is up to 20% more responsive as you type search queries and interact with it. As part of the speed improvements, a feature called “Just Talk” will now be off by default. Just Talk allowed you to search via voice just by bringing the phone to your ear and speaking rather than tapping the microphone icon. Turning off this feature may improve app performance, though you can easily re-enable it under the Settings > Voice Search menu.

Turn Just Talk on or off

Improved look & feel for search results

When searching on a phone, the small screen sometimes makes it difficult to read small fonts or to tap precisely on a link. To help you read and tap with ease, we’ve made the font of our search results bigger and the entire search result is now a tap target rather than just the link.

See the difference between previous (left) and new interface (right) with results now easier to read and select

Thank you for your feedback. Please continue to let us know how we can improve your experience by going to Settings > Help and Feedback > Feedback.

Google Search app is available for devices running iOS 3.0 and above. Download it from the App Store or by scanning the QR code below:


Listen to more languages in Google Translate for Android


 Today we launched an update to Google Translate for Android that allows you to listen to translations in several more languages.

We’ve dramatically improved the quality of our spoken translations in over 15 languages, including Russian, Chinese and Portuguese, and added the ability to listen to three new languages: Japanese, Arabic and Korean. Text-to-speech is one of the most popular features of this mobile interface. Whether you’re learning how to say a foreign phrase, or trying to share information with someone in their language, simply tap the Speaker icon after doing a translation and you’ll hear the difference.

With today’s launch, Google Translate for Android supports translation between 58 languages and can speak translations in 24 languages. The application works on phones and tablets running Android 2.1 and above. To download Google Translate for Android, scan the QR code below, or visit us on the Android Market.

Stay connected to the market, wherever you are


Mobile phones are great for keeping in touch with the latest information, but when there’s a lot of data to look at, a small screen can be a drawback. For financial queries, where you might want to see stock quotes, the latest news, a market overview or portfolio details, we’ve just launched a new approach in Google search.

To try it out, go to on your iPhone or Android-powered device (2.1 or later) and search for your favourite stock ticker symbol.

The first thing you’ll see is an interactive graph shown on a card - you can switch views to different date ranges by tapping on the buttons below the graph.

If you swipe the card from right to left, you’ll get the latest financial news for the company.

Swipe again for a market overview, and if you’re logged in to your Google account and have created a Google Finance portfolio, a further swipe will show a summary of your stock portfolio. Give it a try on your mobile device now to see how it works.

This feature is available in English with support for more languages coming soon. We hope you enjoy it and find it useful.

make your phone your wallet


Today in our New York City office, along with Citi, MasterCard, First Data and Sprint, we gave a demo of Google Wallet, an app that will make your phone your wallet. You’ll be able to tap, pay and save using your phone and near field communication (NFC). We’re field testing Google Wallet now and plan to release it soon.

Google Wallet is a key part of our ongoing effort to improve shopping for both businesses and consumers. It’s aimed at making it easier for you to pay for and save on the goods you want, while giving merchants more ways to offer coupons and loyalty programs to customers, as well as bridging the gap between online and offline commerce.

Because Google Wallet is a mobile app, it will do more than a regular wallet ever could. You'll be able to store your credit cards, offers, loyalty cards and gift cards, but without the bulk. When you tap to pay, your phone will also automatically redeem offers and earn loyalty points for you. Someday, even things like boarding passes, tickets, ID and keys could be stored in Google Wallet.

At first, Google Wallet will support both Citi MasterCard and a Google Prepaid Card, which you’ll be able to fund with almost any payment card. From the outset, you’ll be able to tap your phone to pay wherever MasterCard PayPass is accepted. Google Wallet will also sync your Google Offers, which you’ll be able to redeem via NFC at participating SingleTap™ merchants, or by showing the barcode as you check out. Many merchants are working to integrate their offers and loyalty programs with Google Wallet.

With Google Wallet, we’re building an open commerce ecosystem, and we’re planning to develop APIs that will enable integration with numerous partners. In the beginning, Google Wallet will be compatible with Nexus S 4G by Google, available on Sprint. Over time, we plan on expanding support to more phones.

To learn more please visit our Google Wallet website at

This is just the start of what has already been a great adventure towards the future of mobile shopping. We’re incredibly excited and hope you are, too.

Google Earth optimized for Android-powered tablets


When we launched Google Earth in 2005, most of us were still using flip phones. At the time, the thought of being able to cart around 197 million square miles of Earth in your pocket was still a distant dream. Last year, that dream came to fruition for Android users when we released Google Earth for Android. With the recent release of tablets based on Android 3.0, we wanted to take full advantage of the large screens and powerful processors that this exciting new breed of tablets had to offer.

Today’s update to Google Earth for Android makes Earth look better than ever on your tablet. We’ve added support for fully textured 3D buildings, so your tour through the streets of Manhattan will look more realistic than ever. There’s also a new action bar up top, enabling easier access to search, the option to “fly to your location” and layers such as Places, Panoramio photos, Wikipedia and 3D buildings.

Moving from a mobile phone to a tablet was like going from a regular movie theatre to IMAX. We took advantage of the larger screen size, including features like content pop-ups appearing within Earth view, so you can see more information without switching back and forth between pages.

One of my favorite buildings to fly around in Google Earth has always been the Colosseum in Rome, Italy:

With the larger tablet screen, I can fly around the 3D Colosseum while also browsing user photos from Panoramio. The photos pop up within the imagery so I can interact with them without losing sight of the Colosseum and its surroundings. Also, by clicking on the layer button on the action bar, I can choose which layers I want to browse.

This version is available for devices with Android 2.1 and above. The new tablet design is available for devices with Android 3.0 (Honeycomb) and above. Please visit the Google Earth help center for more information.

To download or update Google Earth, head to in your device’s browser or visit Android Market. Enjoy a whole new world of Google Earth for tablets!


Introducing the new Google Docs app for Android


 Increasingly, people are using mobile phones to access information -- from email to web browsing to editing documents. Part of getting work done on the go is being able to easily access, edit and share content, which is why we’re happy to announce the new Google Docs app for Android.

With this new app it’s easy to filter and search for your content across any Google account, then jump straight into editing docs using the online mobile editors. The app also allows you to easily share items with contacts on your phone, right from within the app.

The Docs app also allows you to upload content from your phone and open documents directly from Gmail. You can also add a widget to your home screen for easy access to three core tasks: jumping to your starred documents, taking a photo to upload, or creating a new document with one tap.

And my favorite feature: Using the app and your phone’s camera, you can turn photos with text into editable Google documents with the power of optical character recognition (OCR). Just create a new ‘Document from Photo' or select the camera icon from the widget, and your converted document will appear in your documents list shortly after you snap the picture. You can also convert photos already stored on your phone by sharing them with the Google Docs app. OCR does a pretty good job capturing unformatted text in English but won't recognize handwriting or some fonts - stay tuned, it will get better over time!

The Google Docs app is currently available in English and works on Android 2.1+ phones. Try it out by scanning the QR code below or by visiting Android Market.

Let us know what you think of the new Google Docs Android app in our forum.

See your location history dashboard and more with Google Maps 5.3 for Android


Today, we’re happy to announce Google Maps 5.3 for Android, which lets you see your Google Location History dashboard, check in at “home,” and add your own aspects for places when rating them.

Location History dashboard
If you’ve enabled Location History for Google Latitude, you’ve been able to visualize interesting trends in your location history with a personal dashboard at on your computer. Now, you can also see your dashboard on your phone by tapping View location history from your Latitude profile. You’ll be able to see right on your phone how far you’ve travelled as well as an estimate of how much time you’ve spent at home, at work, or out.

If you haven’t yet, you can enable Location History from your computer or from Latitude’s Settings menu on your phone. Location History is 100% opt-in and is private to you and nobody else. You can always delete any of your location history from the Manage History tab or correct the estimated work and home locations from the dashboard on your computer.

View your location history dashboard from your Latitude profile on your phone and see estimates of where you’ve spent your time.

Check in at home
Now that you can see how much time you spend at “home”, you might want to let friends know when you’re there. Checking in at places using Latitude is another way to keep a history of places you’ve been and also lets you share when you’re there. I love letting friends and family know when I’m at a cafe or park, but sometimes I want them to know that I’m relaxing at home or made it back safely from a road trip. So now, I can start checking in at “home” in Latitude:
  1. Check in from Latitude and tap “Home - Tap to set your location” at the bottom of the nearby places list if you don’t have one yet.
  2. Use the estimated current address or enter in your home address yourself.
  3. Once you’ve checked in at home once, “Home” will appear at the top of the list when you’re checking in near there.

Like Latitude and other check-ins, checking in at home is entirely opt-in. Your set “home” location is not searchable and only you can check in there. Just like any other check-in, you can choose with whom to share your home check-ins (along with your name and address info).

Add your own aspects for places
When you’re rating places on the go in Maps using Google Places with Hotpot, you could always quickly leave feedback on a specific aspect or characteristic of a place, such as the food or ambiance. Before, we’d automatically include aspects about places that were commonly mentioned in reviews. Now, you can add your own aspects for each place. So if you think a place has a beautiful view or great music, you can add it yourself and quickly share it with the world.

When rating places, you can add your own aspects like “music” for places and leave quick feedback.

To get started, update Google Maps from Android Market on devices with Android OS 1.6+ anywhere Google Maps and Latitude are already available.

New ways to discover great apps on Android Market


We’ve seen tremendous growth in Android Market lately. With over 200,000 apps supporting over 300 Android devices, we’ve had 4.5 billion applications installed to date. But with so many apps available, how do you find the ones you really want? Whether you’re looking for the most popular apps, hot new apps, or just the very best apps available, we want to help make sure that you find what you’re looking for.

Today, we’re excited to announce 5 new features for Android Market focused on helping you find apps you’ll love.

  • New top app charts - We’ve revamped our top app charts to be fresher and country-specific, so you get the most current, relevant results. We’ve also added top new free, top new paid, and top grossing lists, all right on the Android Market home page.   
  • Editors’ Choice - These are some of the very best apps available for Android, as chosen by the Android Market staff. They span everything from games to productivity and beyond.   
  • Top Developers - We’re also recognizing those developers creating the highest quality, most popular, and most notable apps available on Android Market. They’ll get a special icon on our Android Market website, appearing wherever the developer name is shown, starting today for an initial set of over 150 developers.
  • Better related apps - On the left side of an app page, you’ll now see two groups of related apps: apps frequently browsed by people who viewed this app, and apps that people tend to install alongside this app. For example, people who view ScoreMobile, my favorite sports score app, often also view other sports score apps, while those who install ScoreMobile tend to also install apps for specific sports leagues or teams. We’ll also show you related apps once you decide to install an app.
  • Trending apps - Finally, we’ve added a new section to the Android Market homepage showing trending apps – those apps that are quickly growing in daily installs. Look here to stay ahead of the curve and find new apps as they get hot.
We hope you find these features helpful as you explore the many greats apps available on Android Market. These new features are available now on, and will be coming soon to Android Market on phones and tablets.


HTC has confirmed the opening of bootloader


We have already reported that HTC intends to change its policy regarding access to the Android smartphone users to boot the operating system. Now, in an official Twitter, it was reported that the company, as a result of reviewing its position, decided to open the full access to the bootloader. Executive Director Peter Chou (Peter Chou) acknowledged that the criticism by users of sound and said...

Android 2.3.3 Platform, New NFC Capabilities


Several weeks ago we released Android 2.3, which introduced several new forms of communication for developers and users. One of those, Near Field Communications (NFC), let developers get started creating a new class of contactless, proximity-based applications for users.
NFC is an emerging technology that promises exciting new ways to use mobile devices, including ticketing, advertising, ratings, and even data exchange with other devices. We know there’s a strong interest to include these capabilities into many applications, so we’re happy to announce an update to Android 2.3 that adds new NFC capabilities for developers. Some of the features include:

  • A comprehensive NFC reader/writer API that lets apps read and write to almost any standard NFC tag in use today.
  • Advanced Intent dispatching that gives apps more control over how/when they are launched when an NFC tag comes into range.
  • Some limited support for peer-to-peer connection with other NFC devices.
We hope you’ll find these new capabilities useful and we’re looking forward to seeing the innovative apps that you will create using them.
Android 2.3.3 is a small feature release that includes a new API level, 10.
Going forward, we expect most devices shipping with an Android 2.3 platform to run Android 2.3.3 (or later). For an overview of the API changes, see the Android 2.3.3 Version Notes. The Android 2.3.3 SDK platform for development and testing is available through the Android SDK Manager.

Final Android 3.0 Platform and Updated SDK Tools


We are pleased to announce that the full SDK for Android 3.0 is now available to developers. The APIs are final, and you can now develop apps targeting this new platform and publish them to Android Market. The new API level is 11.
For an overview of the new user and developer features, see the Android 3.0 Platform Highlights.
Together with the new platform, we are releasing updates to our SDK Tools (r10) and ADT Plugin for Eclipse (10.0.0). Key features include:

  • UI Builder improvements in the ADT Plugin:
    • New Palette with categories and rendering previews. (details)
    • More accurate rendering of layouts to more faithfully reflect how the layout will look on devices, including rendering status and title bars to more accurately reflect screen space actually available to applications.
    • Selection-sensitive action bars to manipulate View properties.
    • Zoom improvements (fit to view, persistent scale, keyboard access) (details).
    • Improved support for <merge> layouts, as well as layouts with gesture overlays.
  • Traceview integration for easier profiling from ADT. (details)
  • Tools for using the Renderscript graphics engine: the SDK tools now compiles .rs files into Java Programming Language files and native bytecode.
To get started developing or testing applications on Android 3.0, visit the Android Developers site for information about the Android 3.0 platform, the SDK Tools, and the ADT Plugin.

Introducing Renderscript


Renderscript is a key new Honeycomb feature which we haven’t yet discussed in much detail. I will address this in two parts. This post will be a quick overview of Renderscript. A more detailed technical post with a simple example will be provided later.
Renderscript is a new API targeted at high-performance 3D rendering and compute operations. The goal of Renderscript is to bring a lower level, higher performance API to Android developers. The target audience is the set of developers looking to maximize the performance of their applications and are comfortable working closer to the metal to achieve this. It provides the developer three primary tools: A simple 3D rendering API on top of hardware acceleration, a developer friendly compute API similar to CUDA, and a familiar language in C99.
Renderscript has been used in the creation of the new visually-rich YouTube and Books apps. It is the API used in the live wallpapers shipping with the first Honeycomb tablets.
The performance gain comes from executing native code on the device. However, unlike the existing NDK, this solution is cross-platform. The development language for Renderscript is C99 with extensions, which is compiled to a device-agnostic intermediate format during the development process and placed into the application package. When the app is run, the scripts are compiled to machine code and optimized on the device. This eliminates the problem of needing to target a specific machine architecture during the development process.
Renderscript is not intended to replace the existing high-level rendering APIs or languages on the platform. The target use is for performance-critical code segments where the needs exceed the abilities of the existing APIs.
It may seem interesting that nothing above talked about running code on CPUs vs. GPUs. The reason is that this decision is made on the device at runtime. Simple scripts will be able to run on the GPU as compute workloads when capable hardware is available. More complex scripts will run on the CPU(s). The CPU also serves as a fallback to ensure that scripts are always able to run even if a suitable GPU or other accelerator is not present. This is intended to be transparent to the developer. In general, simpler scripts will be able to run in more places in the future. For now we simply leverage the CPU resources and distribute the work across as many CPUs as are present in the device.

The video above, captured through an Android tablet’s HDMI out, is an example of Renderscript compute at work. (There’s a high-def version on YouTube.) In the video we show a simple brute force physics simulation of around 900 particles. The compute script runs each frame and automatically takes advantage of both cores. Once the physics simulation is done, a second graphics script does the rendering. In the video we push one of the larger balls to show the interaction. Then we tilt the tablet and let gravity do a little work. This shows the power of the dual A9s in the new Honeycomb tablet.
Renderscript Graphics provides a new runtime for continuously rendering scenes. This runtime sits on top of HW acceleration and uses the developers’ scripts to provide custom functionality to the controlling Dalvik code. This controlling code will send commands to it at a coarse level such as “turn the page” or “move the list”. The commands the two sides speak are determined by the scripts the developer provides. In this way it’s fully customizable. Early examples of Renderscript graphics were the live wallpapers and 3d application launcher that shipped with Eclair.
With Honeycomb, we have migrated from GL ES 1.1 to 2.0 as the renderer for Renderscript. With this, we have added programmable shader support, 3D model loading, and much more efficient allocation management. The new compiler, based on LLVM, is several times more efficient than acc was during the Eclair-through-Gingerbread time frame. The most important change is that the Renderscript API and tools are now public.

The screenshot above was taken from one of our internal test apps. The application implements a simple scene-graph which demonstrates recursive script to script calling. The Androids are loaded from an A3D file created in Maya and translated from a Collada file. A3D is an on device file format for storing Renderscript objects.
Later we will follow up with more technical information and sample code.

Best Practices for Honeycomb and Tablets


The first tablets running Android 3.0 (“Honeycomb”) will be hitting the streets on Thursday Feb. 24th, and we’ve just posted the full SDK release. We encourage you to test your applications on the new platform, using a tablet-size AVD.
Developers who’ve followed the Android Framework’s guidelines and best practices will find their apps work well on Android 3.0. This purpose of this post is to provide reminders of and links to those best practices.

Moving Toward Honeycomb

There’s a comprehensive discussion of how to work with the new release in Optimizing Apps for Android 3.0. The discussion includes the use of the emulator; most developers, who don’t have an Android tablet yet, should use it to test and update their apps for Honeycomb.
While your existing apps should work well, developers also have the option to improve their apps’ look and feel on Android 3.0 by using Honeycomb features; for example, see The Android 3.0 Fragments API. We’ll have more on that in this space, but in the meantime we recommend reading Strategies for Honeycomb and Backwards Compatibility for advice on adding Honeycomb polish to existing apps.

Specifying Features

There have been reports of apps not showing up in Android Market on tablets. Usually, this is because your application manifest has something like this:
<uses-feature android:name="android.hardware.telephony" />
Many of the tablet devices aren’t phones, and thus Android Market assumes the app is not compatible. See the documentation of <uses-feature>. However, such an app’s use of the telephony APIs might well be optional, in which case it should be available on tablets. There’s a discussion of how to accomplish this in Future-Proofing Your App and The Five Steps to Future Hardware Happiness.


The new environment is different from what we’re used to in two respects. First, you can hold the devices with any of the four sides up and Honeycomb manages the rotation properly. In previous versions, often only two of the four orientations were supported, and there are apps out there that relied on this in ways that will break them on Honeycomb. If you want to stay out of rotation trouble, One Screen Turn Deserves Another covers the issues.
The second big difference doesn’t have anything to do with software; it’s that a lot of people are going to hold these things horizontal (in “landscape mode”) nearly all the time. We’ve seen a few apps that have a buggy assumption that they’re starting out in portrait mode, and others that lock certain screens into portrait or landscape but really shouldn’t.

A Note for Game Developers

A tablet can probably provide a better game experience for your users than any handset can. Bigger is better. It’s going to cost you a little more work than developers of business apps, because quite likely you’ll want to rework your graphical assets for the big screen.
There’s another issue that’s important to game developers: Texture Formats. Read about this in Game Development for Android: A Quick Primer, in the section labeled “Step Three: Carefully Design the Best Game Ever”.
We've also added a convenient way to filter applications in Android Market based on the texture formats they support; see the documentation of <supports-gl-texture> for more details.

Happy Coding

Once you’ve held one of the new tablets in your hands, you’ll want to have your app not just running on it (which it probably already does), but expanding minds on the expanded screen. Have fun!

Animation in Honeycomb


One of the new features ushered in with the Honeycomb release is a new animation system, a set of APIs in a whole new package (android.animation) that makes animating objects and properties much easier than it was before.
"But wait!" you blurt out, nearly projecting a mouthful of coffee onto your keyboard while reading this article, "Isn't there already an animation system in Android?"

Animation Prior to Honeycomb

Indeed, Android already has animation capabilities: there are several classes and lots of great functionality in the android.view.animation package. For example, you can move, scale, rotate, and fade Views and combine multiple animations together in an AnimationSet object to coordinate them. You can specify animations in a LayoutAnimationController to get automatically staggered animation start times as a container lays out its child views. And you can use one of the many Interpolator implementations like AccelerateInterpolator and Bounce to get natural, nonlinear timing behavior.
But there are a couple of major pieces of functionality lacking in the previous system.
For one thing, you can animate Views... and that's it. To a great extent, that's okay. The GUI objects in Android are, after all, Views. So as long as you want to move a Button, or a TextView, or a LinearLayout, or any other GUI object, the animations have you covered. But what if you have some custom drawing in your view that you'd like to animate, like the position of a Drawable, or the translucency of its background color? Then you're on your own, because the previous animation system only understands how to manipulate View objects.
The previous animations also have a limited scope: you can move, rotate, scale, and fade a View... and that's it. What about animating the background color of a View? Again, you're on your own, because the previous animations had a hard-coded set of things they were able to do, and you could not make them do anything else.
Finally, the previous animations changed the visual appearance of the target objects... but they didn't actually change the objects themselves. You may have run into this problem. Let's say you want to move a Button from one side of the screen to the other. You can use a TranslateAnimation to do so, and the button will happily glide along to the other side of the screen. And when the animation is done, it will gladly snap back into its original location. So you find the setFillAfter(true) method on Animation and try it again. This time the button stays in place at the location to which it was animated. And you can verify that by clicking on it - Hey! How come the button isn't clicking? The problem is that the animation changes where the button is drawn, but not where the button physically exists within the container. If you want to click on the button, you'll have to click the location that it used to live in. Or, as a more effective solution (and one just a tad more useful to your users), you'll have to write your code to actually change the location of the button in the layout when the animation finishes.
It is for these reasons, among others, that we decided to offer a new animation system in Honeycomb, one built on the idea of "property animation."

Property Animation in Honeycomb

The new animation system in Honeycomb is not specific to Views, is not limited to specific properties on objects, and is not just a visual animation system. Instead, it is a system that is all about animating values over time, and assigning those values to target objects and properties - any target objects and properties. So you can move a View or fade it in. And you can move a Drawable inside a View. And you can animate the background color of a Drawable. In fact, you can animate the values of any data structure; you just tell the animation system how long to run for, how to evaluate between values of a custom type, and what values to animate between, and the system handles the details of calculating the animated values and setting them on the target object.
Since the system is actually changing properties on target objects, the objects themselves are changed, not simply their appearance. So that button you move is actually moved, not just drawn in a different place. You can even click it in its animated location. Go ahead and click it; I dare you.
I'll walk briefly through some of the main classes at work in the new system, showing some sample code when appropriate. But for a more detailed view of how things work, check out the API Demos in the SDK for the new animations. There are many small applications written for the new Animations category (at the top of the list of demos in the application, right before the word App. I like working on animation because it usually comes first in the alphabet).
In fact, here's a quick video showing some of the animation code at work. The video starts off on the home screen of the device, where you can see some of the animation system at work in the transitions between screens. Then the video shows a sampling of some of the API Demos applications, to show the various kinds of things that the new animation system can do. This video was taken straight from the screen of a Honeycomb device, so this is what you should see on your system, once you install API Demos from the SDK.


Animator is the superclass of the new animation classes, and has some of the common attributes and functionality of the subclasses. The subclasses are ValueAnimator, which is the core timing engine of the system and which we'll see in the next section, and AnimatorSet, which is used to choreograph multiple animators together into a single animation. You do not use Animator directly, but some of the methods and properties of the subclasses are exposed at this superclass level, like the duration, startDelay and listener functionality.
The listeners tend to be important, because sometimes you want to key some action off of the end of an animation, such as removing a view after an animation fading it out is done. To listen for animator lifecycle events, implement the AnimatorListener interface and add your listener to the Animator in question. For example, to perform an action when the animator ends, you could do this:
    anim.addListener(new Animator.AnimatorListener() {
public void onAnimationStart(Animator animation) {}
public void onAnimationEnd(Animator animation) {
// do something when the animation is done
public void onAnimationCancel(Animator animation) {}
public void onAnimationRepeat(Animator animation) {}
As a convenience, there is an adapter class, AnimatorListenerAdapter, that stubs out these methods so that you only need to override the one(s) that you care about:

anim.addListener(new AnimatorListenerAdapter() {
public void onAnimationEnd(Animator animation) {
// do something when the animation is done


ValueAnimator is the main workhorse of the entire system. It runs the internal timing loop that causes all of a process's animations to calculate and set values and has all of the core functionality that allows it to do this, including the timing details of each animation, information about whether an animation repeats, listeners that receive update events, and the capability of evaluating different types of values (see TypeEvaluator for more on this). There are two pieces to animating properties: calculating the animated values and setting those values on the object and property in question. ValueAnimator takes care of the first part; calculating the values. The ObjectAnimator class, which we'll see next, is responsible for setting those values on target objects.
Most of the time, you will want to use ObjectAnimator, because it makes the whole process of animating values on target objects much easier. But sometimes you may want to use ValueAnimator directly. For example, the object you want to animate may not expose setter functions necessary for the property animation system to work. Or perhaps you want to run a single animation and set several properties from that one animated value. Or maybe you just want a simple timing mechanism. Whatever the case, using ValueAnimator is easy; you just set it up with the animation properties and values that you want and start it. For example, to animate values between 0 and 1 over a half-second, you could do this:
    ValueAnimator anim = ValueAnimator.ofFloat(0f, 1f);
But animations are a bit like the tree in the forest philosophy question ("If a tree falls in the forest and nobody is there to hear it, does it make a sound?"). If you don't actually do anything with the values, does the animation run? Unlike the tree question, this one has an answer: of course it runs. But if you're not doing anything with the values, it might as well not be running. If you started it, chances are you want to do something with the values that it calculates along the way. So you add a listener to it, to listen for updates at each frame. And when you get the callback, you call getAnimatedValue(), which returns an Object, to find out what the current value is.
    anim.addUpdateListener(new ValueAnimator.AnimatorUpdateListener() {
public void onAnimationUpdate(ValueAnimator animation) {
Float value = (Float) animation.getAnimatedValue();
// do something with value...
Of course, you don't necessarily always want to animate float values. Maybe you need to animate something that's an integer instead:
    ValueAnimator anim = ValueAnimator.ofInt(0, 100);
or in XML:
    <animator xmlns:android=""
In fact, maybe you need to animate something entirely different, like a Point, or a Rect, or some custom data structure of your own. The only types that the animation system understands by default are float and int, but that doesn't mean that you're stuck with those two types. You can to use the Object version of the factory method, along with a TypeEvaluator (explained later), to tell the system how to calculate animated values for this unknown type:
    Point p0 = new Point(0, 0);
Point p1 = new Point(100, 200);
ValueAnimator anim = ValueAnimator.ofObject(pointEvaluator, p0, p1);
There are other animation attributes that you can set on a ValueAnimator besides duration, including:
  • setStartDelay(long): This property controls how long the animation waits after a call to start() before it starts playing.
  • setRepeatCount(int) and setRepeatMode(int): These functions control how many times the animation repeats and whether it repeats in a loop or reverses direction each time.
  • setInterpolator(TimeInterpolator): This object controls the timing behavior of the animation. By default, animations accelerate into and decelerate out of the motion, but you can change that behavior by setting a different interpolator. This function acts just like the one of the same name in the previous Animation class; it's just that the type of the parameter (TimeInterpolator) is different from that of the previous version (Interpolator). But the TimeInterpolator interface is just a super-interface of the existing Interpolator interface in the android.view.animation package, so you can use any of the existing Interpolator implementations, like Bounce, as arguments to this function on ValueAnimator.


ObjectAnimator is probably the main class that you will use in the new animation system. You use it to construct animations with the timing and values that ValueAnimator takes, and also give it a target object and property name to animate. It then quietly animates the value and sets those animated values on the specified object/property. For example, to fade out some object myObject, we could animate the alpha property like this:
    ObjectAnimator.ofFloat(myObject, "alpha", 0f).start();
Note, in this example, a special feature that you can use to make your animations more succinct; you can tell it the value to animate to, and it will use the current value of the property as the starting value. In this case, the animation will start from whatever value alpha has now and will end up at 0.
You could create the same thing in an XML resource as follows:
    <objectAnimator xmlns:android=""
Note, in the XML version, that you cannot set the target object; this must be done in code after the resource is loaded:
    ObjectAnimator anim = AnimatorInflator.loadAnimator(context, resID);
There is a hidden assumption here about properties and getter/setter functions that you have to understand before using ObjectAnimator: you must have a public "set" function on your object that corresponds to the property name and takes the appropriate type. Also, if you use only one value, as in the example above, your are asking the animation system to derive the starting value from the object, so you must also have a public "get" function which returns the appropriate type. For example, the class of myObject in the code above must have these two public functions in order for the animation to succeed:
    public void setAlpha(float value);
public float getAlpha();
So by passing in a target object of some type and the name of some property foo supposedly on that object, you are implicitly declaring a contract that that object has at least a setFoo() function and possibly also a getFoo() function, both of which handle the type used in the animation declaration. If all of this is true, then the animation will be able to find those setter/getter functions on the object and set values during the animation. If the functions do not exist, then the animation will fail at runtime, since it will be unable to locate the functions it needs. (Note to users of ProGuard, or other code-stripping utilities: If your setter/getter functions are not used anywhere else in the code, make sure you tell the utility to leave the functions there, because otherwise they may get stripped out. The binding during animation creation is very loose and these utilities have no way of knowing that these functions will be required at runtime.)

View properties

The observant reader, or at least the ones that have not yet browsed on to some other article, may have pinpointed a flaw in the system thus far. If the new animation framework revolves around animating properties, and if animations will be used to animate, to a large extent, View objects, then how can they be used against the View class, which exposes none of its properties through set/get functions?
Excellent question: you get to advance to the bonus round and keep reading.
The way it works is that we added new properties to the View class in Honeycomb. The old animation system transformed and faded View objects by just changing the way that they were drawn. This was actually functionality handled in the container of each View, because the View itself had no transform properties to manipulate. But now it does: we've added several properties to View to make it possible to animate Views directly, allowing you to not only transform the way a View looks, but to transform its actual location and orientation. Here are the new properties in View that you can set, get and animate directly:
  • translationX and translationY: These properties control where the View is located as a delta from its left and top coordinates which are set by its layout container. You can run a move animation on a button by animating these, like this: ObjectAnimator.ofFloat(view, "translationX", 0f, 100f);.
  • rotation, rotationX, and rotationY: These properties control the rotation in 2D (rotation) and 3D around the pivot point.
  • scaleX and scaleY: These properties control the 2D scaling of a View around its pivot point.
  • pivotX and pivotY: These properties control the location of the pivot point, around which the rotation and scaling transforms occur. By default, the pivot point is centered at the center of the object.
  • x and y: These are simple utility properties to describe the final location of the View in its container, as a sum of the left/top and translationX/translationY values.
  • alpha: This is my personal favorite property. No longer is it necessary to fade out an object by changing a value on its transform (a process which just didn't seem right). Instead, there is an actual alpha value on the View itself. This value is 1 (opaque) by default, with a value of 0 representing full transparency (i.e., it won't be visible). To fade a View out, you can do this: ObjectAnimator.ofFloat(view, "alpha", 0f);
Note that all of the "properties" described above are actually available in the form of set/get functions (e.g., setRotation() and getRotation() for the rotation property). This makes them both possible to access from the animation system and (probably more importantly) likely to do the right thing when changed. That is, you don't want to scale an object and have it just sit there because the system didn't know that it needed to redraw the object in its new orientation; each of the setter functions takes care to run the appropriate invalidation step to make the rendering work correctly.


This class, like the previous AnimationSet, exists to make it easier to choreograph multiple animations. Suppose you want several animations running in tandem, like you want to fade out several views, then slide in other ones while fading them in. You could do all of this with separate animations and either manually starting the animations at the right times or with startDelays set on the various delayed animations. Or you could use AnimatorSet to do all of that for you. AnimatorSet allows you to animations that play together, playTogether(Animator...), animations that play one after the other, playSequentially(Animator...), or you can organically build up a set of animations that play together, sequentially, or with specified delays by calling the functions in the AnimatorSet.Builder class, with(), before(), and after(). For example, to fade out v1 and then slide in v2 while fading it, you could do something like this:
    ObjectAnimator fadeOut = ObjectAnimator.ofFloat(v1, "alpha", 0f);
ObjectAnimator mover = ObjectAnimator.ofFloat(v2, "translationX", -500f, 0f);
ObjectAnimator fadeIn = ObjectAnimator.ofFloat(v2, "alpha", 0f, 1f);
AnimatorSet animSet = new AnimatorSet().play(mover).with(fadeIn).after(fadeOut);;
Like ValueAnimator and ObjectAnimator, you can create AnimatorSet objects in XML resources as well.


I wanted to talk about just one more thing, and then I'll leave you alone to explore the code and play with the API demos. The last class I wanted to mention is TypeEvaluator. You may not use this class directly for most of your animations, but you should that it's there in case you need it. As I said earlier, the system knows how to animate float and int values, but otherwise it needs some help knowing how to interpolate between the values you give it. For example, if you want to animate between the Point values in one of the examples above, how is the system supposed to know how to interpolate the values between the start and end points? Here's the answer: you tell it how to interpolate, using TypeEvaluator.
TypeEvaluator is a simple interface that you implement that the system calls on each frame to help it calculate an animated value. It takes a floating point value which represents the current elapsed fraction of the animation and the start and end values that you supplied when you created the animation and it returns the interpolated value between those two values at that fraction. For example, here's the built-in FloatEvaluator class used to calculate animated floating point values:
    public class FloatEvaluator implements TypeEvaluator {
public Object evaluate(float fraction, Object startValue, Object endValue) {
float startFloat = ((Number) startValue).floatValue();
return startFloat + fraction * (((Number) endValue).floatValue() - startFloat);
But how does it work with a more complex type? For an example of that, here is an implementation of an evaluator for the Point class, from our earlier example:
    public class PointEvaluator implements TypeEvaluator {
public Object evaluate(float fraction, Object startValue, Object endValue) {
Point startPoint = (Point) startValue;
Point endPoint = (Point) endValue;
return new Point(startPoint.x + fraction * (endPoint.x - startPoint.x),
startPoint.y + fraction * (endPoint.y - startPoint.y));
Basically, this evaluator (and probably any evaluator you would write) is just doing a simple linear interpolation between two values. In this case, each 'value' consists of two sub-values, so it is linearly interpolating between each of those.
You tell the animation system to use your evaluator by either calling the setEvaluator() method on ValueAnimator or by supplying it as an argument in the Object version of the factory method. To continue our earlier example animating Point values, you could use our new PointEvaluator class above to complete that code:
    Point p0 = new Point(0, 0);
Point p1 = new Point(100, 200);
ValueAnimator anim = ValueAnimator.ofObject(new PointEvaluator(), p0, p1);
One of the ways that you might use this interface is through the ArgbEvaluator implementation, which is included in the Android SDK. If you animate a color property, you will probably either use this evaluator automatically (which is the case if you create an animator in an XML resource and supply colors as values) or you can set it manually on the animator as described in the previous section.

But Wait, There's More!

There's so much more to the new animation system that I haven't gotten to. There's the repetition functionality, the listeners for animation lifecycle events, the ability to supply multiple values to the factory methods to get animations between more than just two endpoints, the ability to use the Keyframe class to specify a more complex time/value sequence, the use of PropertyValuesHolder to specify multiple properties to animate in parallel, the LayoutTransition class for automating simple layout animations, and so many other things. But I really have to stop writing soon and get back to working on the code. I'll try to post more articles in the future on some of these items, but also keep an eye on my blog at graphics-geek  for upcoming articles, tutorials, and videos on this and related topics. Until then, check out the API demos, read the overview of Property Animation posted with the 3.0 SDK, dive into the code, and just play with it.
