Welcome to Android 3.0!

The Android 3.0 platform introduces many new and exciting features for users and developers.
This document provides a glimpse of some of the new features and technologies, as delivered in
Android 3.0. For a more detailed look at new developer APIs, see the Android 3.0 Platform document.

New User Features

New UI designed from the ground up for tabletscamera

Android 3.0 is a new version of the Android platform that is specifically optimized for devices with larger screen sizes, particularly tablets. It introduces a brand new, truly virtual and “holographic” UI design, as well as an elegant, content-focused interaction model.

Android 3.0 builds on the things people love most about Android — refined multitasking, rich notifications, Home screen customization, widgets, and more — and transforms them with a vibrant, 3D experience and deeper interactivity, making them familiar but even better than before.

The new UI brings fresh paradigms for interaction, navigation, and customization and makes them available to all applications — even those built for earlier versions of the platform. Applications written for Android 3.0 are able to use an extended set of UI objects, powerful graphics, and media capabilities to engage users in new ways.

System Bar, for global status and notifications

Across the system and in all applications, users have quick access to notifications, system status, and soft navigation buttons in a System Bar, available at the bottom of the screen. The System Bar is always present and is a key touchpoint for users, but in a new “lights out mode” can also be dimmed for full-screen viewing, such as for videos.

Action Bar, for application controlcontacts

In every application, users have access to contextual options, navigation, widgets, or other types of content in an Action Bar, displayed at the top of the screen. The Action Bar is always present when an application is in use, although its content, theme, and other properties are managed by the application rather than the system. The Action Bar is another key touchpoint for users, especially with action items and an overflow dropdown menu, which users frequently access in a similar manner in most applications.

Customizable Home screens

Five customizable Home screens give users instant access to all parts of the system from any context. Each screen offers a large grid that maintains spatial arrangement in all orientations. Users can select and manipulate Home screen widgets, app shortcuts, and wallpapers using a dedicated visual layout mode. Visual cues and drop shadows improve visibility when adjusting the layout of shortcuts and widgets. Each Home screen also offers a familiar launcher for access to all installed applications, as well as a Search box for universal search of apps, contacts, media files, web content, and more.

Recent Apps, for easy visual multitasking

Multitasking is a key strength of Android and it is central to the Android 3.0 experience. As users launch applications to handle various tasks, they can use the Recent Apps list in the System Bar to see the tasks underway and quickly jump from one application context to another. To help users rapidly identify the task associated with each app, the list shows a snapshot of its actual state when the user last viewed it.

browserRedesigned keyboard

The Android soft keyboard is redesigned to make entering text fast and accurate on larger screen sizes. The keys are reshaped and repositioned for improved targeting, and new keys have been added, such as a Tab key, to provide richer and more efficient text input. Users can touch-hold keys to access menus of special characters and switch text/voice input modes from a button in the System Bar.

Improved text selection, copy and paste

When entering or viewing text, a new UI lets users quickly select a word by press-hold and then adjust the selection area as needed by dragging a set of bounding arrows to new positions. Users can then select an action from the Action Bar, such as copy to the clipboard, share, paste, web search, or find.

widgetsNew connectivity options

Android 3.0 includes new connectivity features that add versatility and convenience for users. Built-in support for Media/Picture Transfer Protocol lets users instantly sync media files with a USB-connected camera or desktop computer, without needing to mount a USB mass-storage device. Users can also connect full keyboards over either USB or Bluetooth, for a familiar text-input environment. For improved wi-fi connectivity, a new combo scan reduces scan times across bands and filters. New support for Bluetooth tethering means that more types of devices can share the network connection of an Android-powered device.

Updated set of standard apps

The Android 3.0 platform includes an updated set of standard applications that are designed for use on larger screen devices. The sections below highlight some of the new features.


The browser includes new features that let users navigate and organize more efficiently. Multiple tabs replace browser windows and a new “incognito” mode allows anonymous browsing. Bookmarks and history are presented and managed in a single unified view. Users can now choose to automatically sign into Google sites on the browser with a supplied account and sync bookmarks with Google Chrome. New multitouch support is now available to JavaScript and plugins. Users can enjoy a better browsing experience at non-mobile sites through an improved zoom and viewport model, overflow scrolling, support for fixed positioning, and more.

Camera and Gallery

The Camera application has been redesigned to take advantage of a larger screen for quick access to exposure, focus, flash, zoom, front-facing camera, and more. To let users capture scenes in new ways, it adds built-in support for time-lapse video recording. The Gallery application lets users view albums and other collections in full-screen mode, with easy access to thumbnails for other photos in the collection.


The Contacts app uses a new two-pane UI and Fast Scroll to let users easily organize and locate contacts. The application offers improved formatting of international phone numbers as user types, based on home country and an international number parsing library. Contact information is presented in a card-like UI, making it easier for users to read and edit contacts.


The Email application uses a new two-pane UI to make viewing and organizing messages more efficient. The app lets users select one or more messages, then select an action from the Action Bar, such as moving them to a folder. Users can sync attachments for later viewing and keep track of email using a home screen Widget.

New UI Framework for creating great tablet appstasks

Activity fragments, for greater control of content and design flexibility

Starting with Android 3.0, developers can break the Activities of their applications into subcomponents called Fragments, then combine them in a variety of ways to create a richer, more interactive experience. For example, an application can use a set of Fragments to create a true multipane UI, with the user being able to interact with each pane independently. Fragments can be added, removed, replaced, and animated inside an Activity dynamically, and they are modular and reusable across multiple Activities. Because they are modular, Fragments also offer an efficient way for developers to write applications that can run properly on both larger screen as well as smaller screen devices.

Redesigned UI widgets

Android 3.0 offers an updated set of UI widgets that developers can use to quickly add new types of content to their applications. The new UI widgets are redesigned for use on larger screens such as tablets and incorporate the new holographic UI theme. Several new widget types are available, including a 3D stack, search box, a date/time picker, number picker, calendar, popup menu, and others. Most of the redesigned UI widgets can now be used as remote views in application widgets displayed on the home screen. Applications written for earlier versions can inherit the new Widget designs and themes.

Expanded Home screen widgets

Home screen widgets are popular with users because they offer fast access to application-specific data directly from the home screen. Android 3.0 lets developers take home screen widgets to the next level, offering more types of content and new modes of interaction with users. Developers can now use more standard UI widget types home screen widgets, including widgets that let users flip through collections of content as 3D stacks, grids, or lists. Users can interact with the home screen widgets in new ways, such as by using touch gestures to scroll and flip the content displayed in a widget.

copyPersistent Action Bar

The platform provides each application with its own instance of the Action Bar at the top of the screen, which the application can use to give the user quick access to contextual options, widgets, status, navigation, and more. The application can also customize the display theme of its Action Bar instance. The Action Bar lets developers expose more features of their applications to users in a familiar location, while also unifying the experience of using an application that spans multiple Activities or states.

Richer notifications

Notifications are a key part of the Android user experience because they let applications show key updates and status information to users in real time. Android 3.0 extends this capability, letting developers include richer content and control more properties. A new builder class lets developers quickly create notifications that include large and small icons, a title, a priority flag, and any properties already available in previous versions. Notifications can offer more types of content by building on the expanded set of UI Widgets that are now available as remote Views.

Multiselect, clipboard, and drag-and-drop

The platform offers convenient new interaction modes that developers can use. For managing collections of items in lists or grids, developers can offer a new multiselect mode that lets users choose multiple items for an action. Developers can also use a new system-wide Clipboard to let users easily copy any type of data into and out of their applications. To make it easier for users to manage and organize files, developers can now add drag-and-drop interaction through a DragEvent framework.

High-performance 2D and 3D graphicsmail_drag

New animation framework

The platform includes a flexible new animation framework that lets developers easily animate the properties of UI elements such as Views, Widgets, Fragments, Drawables, or any arbitrary object. Animations can create fades or movement between states, loop an animated image or an existing animation, change colors, and much more. Adding animation to UI elements can add visual interest to an application and refine the user experience, to keep users engaged.

Hardware-accelerated 2D graphics

Android 3.0 offers a new hardware-accelerated OpenGL renderer that gives a performance boost to many common graphics operations for applications running in the Android framework. When the renderer is enabled, most operations in Canvas, Paint, Xfermode, ColorFilter, Shader, and Camera are accelerated. Developers can control how hardware-acceleration is applied at every level, from enabling it globally in an application to enabling it in specific Activities and Views inside the application.

Renderscript 3D graphics engine

Renderscript is a runtime 3D framework that provides both an API for building 3D scenes as well as a special, platform-independent shader language for maximum performance. Using Renderscript, you can accelerate graphics operations and data processing. Renderscript is an ideal way to create high-performance 3D effects for applications, wallpapers, carousels, and more.

Support for multicore processor architectures

Android 3.0 is the first version of the platform designed to run on either single or multicore processor architectures. A variety of changes in the Dalvik VM, Bionic library, and elsewhere add support for symmetric multiprocessing in multicore environments. These optimizations can benefit all applications, even those that are single-threaded. For example, with two active cores, a single-threaded application might still see a performance boost if the Dalvik garbage collector runs on the second core. The system will arrange for this automatically.

Rich multimedia and connectivityhomescreen_cust_port

HTTP Live streaming

Applications can now pass an M3U playlist URL to the media framework to begin an HTTP Live streaming session. The media framework supports most of the HTTP Live streaming specification, including adaptive bit rate.

Pluggable DRM framework

Android 3.0 includes an extensible DRM framework that lets applications manage protected content according to a variety of DRM mechanisms that may be available on the device. For application developers, the framework API offers an consistent, unified API that simplifies the management of protected content, regardless of the underlying DRM engines.

Digital media file transfer

The platform includes built-in support for Media/Picture Transfer Protocol (MTP/PTP) over USB, which lets users easily transfer any type of media files between devices and to a host computer. Developers can build on this support, creating applications that let users create or manage media files that they may want to transfer or share across devices.

More types of connectivity

The platform offers new connectivity that developers can build on. API support for Bluetooth A2DP and HSP profiles lets applications query Bluetooth profiles for connected devices, audio state, and more, then notify the user. For example, a music application can check connectivity and status and let the user know that music is playing through a stereo headset. Applications can also register to receive system broadcasts of pre-defined vendor-specific AT commands, such as Platronics Xevent. For example, an application could receive broadcasts that indicate a connected device’s battery level and could notify the user or take other action as needed. Applications can also take advantage of the platform’s new support for full keyboards connected by USB or Bluetooth.

Enhancements for enterprisehome_hero1

In Android 3.0, developers of device administration applications can support new types of policies, including policies for encrypted storage, password expiration, password history, and password complex characters required.

Compatibility with existing apps

Android 3.0 brings a new UI designed for tablets and other larger screen devices, but it also is fully compatible with applications developed for earlier versions of the platform, or for smaller screen sizes. Existing applications can seamlessly participate in the new holographic UI theme without code changes, by adding a single attribute in their manifest files. The platform emulates the Menu key, which is replaced by the overflow menu in the Action Bar in the new UI. Developers wanting to take fuller advantage of larger screen sizes can also create dedicated layouts and assets for larger screens and add them to their existing applications.

Android 4.0

Introducing Android 4.0lock-sm

Android 4.0 (Ice Cream Sandwich) is the latest version of the Android platform for
phones, tablets, and more. It builds on the things people love most about Android — easy
multitasking, rich notifications, customizable home screens, resizable widgets, and deep
interactivity — and adds powerful new ways of communicating and sharing.

Simple, Beautiful, Useful

Refined, evolved UI

Focused on bringing the power of Android to the surface, Android 4.0 makes common actions
more visible and lets you navigate with simple, intuitive gestures. Refined animations
and feedback throughout the system make interactions engaging and interesting. An
entirely new typeface optimized for high-resolution screens improves readability and
brings a polished, modern feel to the user interface.

Virtual buttons in the System Bar let you navigate instantly to Back, Home, and Recent
Apps. The System Bar and virtual buttons are present across all apps, but can be dimmed
by applications for full-screen viewing. You can access each application’s contextual
options in the Action Bar, displayed at the top (and sometimes also at the bottom) of the

Multitasking is a key strength of Android and it’s made even easier and more visual on
Android 4.0. The Recent Apps button lets you jump instantly from one task to another
using the list in the System Bar. The list pops up to show thumbnail images of apps used
recently — tapping a thumbnail switches to the app.

For incoming calls, you can respond instantly by text.

Rich and interactive notifications let you keep in constant touch with incoming messages,
play music tracks, see real-time updates from apps, and much more. On smaller-screen
devices, notifications appear at the top of the screen, while on larger-screen devices
they appear in the System Bar.

tasks-smHome screen folders and favorites tray

New home screen folders offer a new way for you to group your apps and shortcuts
logically, just by dragging one onto another. Also, in All Apps launcher, you can now
simply drag an app to get information about it or immediately uninstall it, or disable a
pre-installed app.

The All Apps launcher (left) and resizable widgets (right) give you apps and rich
content from the home screen.

On smaller-screen devices, the home screen now includes a customizable favorites tray
visible from all home screens. You can drag apps, shortcuts, folders, and other priority
items in or out of the favorites tray for instant access from any home screen.

Resizable widgets

Home screens in Android 4.0 are designed to be content-rich and customizable. You can do
much more than add shortcuts — you can embed live application content directly through
interactive widgets. Widgets let you check email, flip through a calendar, play music,
check social streams, and more — right from the home screen, without having to launch
apps. Widgets are resizable, so you can expand them to show more content or shrink them
to save space.

New lock screen actionsall_apps-sm

The lock screens now let you do more without unlocking. From the slide lock screen, you
can jump directly to the camera for a picture or pull down the notifications window to
check for messages. When listening to music, you can even manage music tracks and see
album art.

Quick responses for incoming calls

When an incoming call arrives, you can now quickly respond by text message, without
needing to pick up the call or unlock the device. On the incoming call screen, you simply
slide a control to see a list of text responses and then tap to send and end the call.
You can add your own responses and manage the list from the Settings app.

Swipe to dismiss notifications, tasks, and browser tabs

Android 4.0 makes managing notifications, recent apps, and browser tabs even easier. You
can now dismiss individual notifications, apps from the Recent Apps list, and browser
tabs with a simple swipe of a finger.

Improved text input and spell-checking

The soft keyboard in Android 4.0 makes text input even faster and more accurate. Error
correction and word suggestion are improved through a new set of default dictionaries and
more accurate heuristics for handling cases such as double-typed characters, skipped
letters, and omitted spaces. Word suggestion is also improved and the suggestion strip is
simplified to show only three words at a time.

To fix misspelled words more easily, Android 4.0 adds a spell-checker that locates and
underlines errors and suggests replacement words. With one tap, you can choose from
multiple spelling suggestions, delete a word, or add it to the dictionary. You can even
tap to see replacement suggestions for words that are spelled correctly. For specialized
features or additional languages, you can now download and install third-party
dictionaries, spell-checkers, and other text services.

Powerful voice input enginecontact-call-sm

Android 4.0 introduces a powerful new voice input engine that offers a continuous “open
microphone” experience and streaming voice recognition. The new voice input engine lets
you dictate the text you want, for as long as you want, using the language you want. You
can speak continously for a prolonged time, even pausing for intervals if needed, and
dictate punctuation to create correct sentences. As the voice input engine enters text,
it underlines possible dictation errors in gray. After dictating, you can tap the
underlined words to quickly replace them from a list of suggestions.

Control over network data

Mobile devices can make extensive use of network data for streaming content,
synchronizing data, downloading apps, and more. To meet the needs of you with tiered or
metered data plans, Android 4.0 adds new controls for managing network data usage.

In the Settings app, colorful charts show the total data usage on each network type
(mobile or Wi-Fi), as well as amount of data used by each running application. Based on
your data plan, you can optionally set warning levels or hard limits on data usage or
disable mobile data altogether. You can also manage the background data used by
individual applications as needed.

Designed for accessibilitycamera-lock-sm

A variety of new features greatly enhance the accessibility of Android 4.0 for blind or
visually impaired users. Most important is a new explore-by-touch mode that lets you
navigate without having to see the screen. Touching the screen once triggers audible
feedback that identifies the UI component below; a second touch in the same component
activates it with a full touch event. The new mode is especially important to support
users on new devices that use virtual buttons in the System Bar, rather than dedicated
hardware buttons or trackballs. Also, standard apps are updated to offer an improved
accessibility experience. The Browser supports a script-based screen reader for reading
favorite web content and navigating sites. For improved readability, you can also
increase the default font size used across the system.

The accessibility experience begins at first setup — a simple touch gesture during setup
(clockwise square from upper left) activates all accessibility features and loads a setup
tutorial. Once accessibility features are active, everything visible on the screen can be
spoken aloud by the standard screen reader.

Communication and sharing

People and profiles

Throughout the system, your social groups, profiles, and contacts are linked together and
integrated for easy accessibility. At the center is a new People app that offers richer
profile information, including a large profile picture, phone numbers, addresses and
accounts, status updates, events, and a new button for connecting on integrated social

Your contact information is stored in a new “Me” profile, allowing easier sharing with
apps and people. All of your integrated contacts are displayed in an easy to manage list,
including controls over which contacts are shown from any integrated account or social
network. Wherever you navigate across the system, tapping a profile photo displays Quick
Contacts, with large profile pictures, shortcuts to phone numbers, text messaging, and

Unified calendar, visual voicemail

To help organize appointments and events, an updated Calendar app brings together
personal, work, school, and social agendas. With user permission, other applications can
contribute events to the calendar and manage reminders, for an integrated view across
multiple calendar providers. The app is redesigned to let you manage events more easily.
Calendars are color-coded and you can swipe left or right to change dates and pinch to
zoom in or out agendas.

In the phone app, a new visual voicemail features integrates incoming messages, voice
transcriptions, and audio files from one or more providers. Third-party applications can
integrate with the Phone app to add your own voice messages, transcriptions, and more to
the visual voicemail inbox.

Rich and versatile camera capabilities

The Camera app includes many new features that let you capture special moments with
great photos and videos. After capturing images, you can edit and share them easily
with friends.

When taking pictures, continuous focus, zero shutter lag exposure, and decreased
shot-to-shot speed help capture clear, precise images. Stabilized image zoom lets you
compose photos and video in the way you want, including while video is recording. For
new flexibility and convenience while shooting video, you can now take snapshots at
full video resolution just by tapping the screen as video continues to record.

To make it easier to take great pictures of people, built-in face detection locates
faces in the frame and automatically sets focus. For more control, you can tap to focus
anywhere in the preview image.

For capturing larger scenes, the Camera introduces a single-motion panorama mode. In
this mode, you start an exposure and then slowly turn the Camera to encompass as wide a
perspective as needed. The Camera assembles the full range of continuous imagery into a
single panoramic photo.

After taking a picture or video, you can quickly share it by email, text message,
bluetooth, social networks, and more, just by tapping the thumbnail in the camera

Redesigned Gallery app with photo editor

The Gallery app now makes it easier to manage, show, and share photos and videos. For
managing collections, a redesigned album layout shows many more albums and offers
larger thumbnails. There are many ways to sort albums, including by time, location,
people, and tags. To help pictures look their best, the Gallery now includes a powerful
photo editor. You can crop and rotate pictures, set levels, remove red eyes, add
effects, and much more. After retouching, you can select one or multiple pictures or
videos to share instantly over email, text messaging, bluetooth, social networks, or
other apps.

An improved Picture Gallery widget lets you look at pictures directly on the home
screen. The widget can display pictures from a selected album, shuffle pictures from
all albums, or show a single image. After adding the widget to the home screen, you can
flick through the photo stacks to locate the image you want, then tap to load it in

Live Effects for transforming video

Live Effects is a collection of graphical transformations that add interest and fun to
videos captured in the Camera app. For example, you can change the background behind
them to any stock or custom image, for just the right setting when shooting video. Also
available for video is Silly Faces, a set of morphing effects that use state-of-the-art
face recognition and GPU filters to transform facial features. For example, you can use
effects such as small eyes, big mouth, big nose, face squeeze, and more. Outside of the
Camera app, Live Effects is available during video chat in the Google Talk app.

Sharing with screenshots

You can now share what’s on your screens more easily by taking screenshots. Hardware
buttons let them snap a screenshot and store it locally. Afterward, you can view, edit,
and share the screen shot in Gallery or a similar app.

Cloud-connected experience

Android has always been cloud-connected, letting you browse the web and sync photos,
apps, games, email, and contacts — wherever you are and across all of your devices.
Android 4.0 adds new browsing and email capabilities to let you take even more with
them and keep communication organized.

Powerful web browsing

The Android Browser offers an experience that’s as rich and convenient as a desktop
browser. It lets you instantly sync and manage Google Chrome bookmarks from all of your
accounts, jump to your favorite content faster, and even save it for reading later in
case there’s no network available.

To get the most out of web content, you can now request full desktop versions of web
sites, rather than their mobile versions. You can set your preference for web sites
separately for each browser tab. For longer content, you can save a copy for offline
reading. To find and open saved pages, you can browse a visual list that’s included
with browser bookmarks and history. For better readability and accessibility, you can
increase the browser’s zoom levels and override the system default text sizes.

Across all types of content, the Android Browser offers dramatically improved page
rendering performance through updated versions of the WebKit core and the V8 Crankshaft
compilation engine for JavaScript. In benchmarks run on a Nexus S device, the Android
4.0 browser showed an improvement of nearly 220% over the Android 2.3 browser in the V8
Benchmark Suite and more than 35% in the SunSpider 9.1 JavaScript Benchmark. When run
on a Galaxy Nexus device, the Android 4.0 browser showed improvement of nearly 550% in
the V8 benchmark and nearly 70% in the SunSpider benchmark.

Improved email

In Android 4.0, email is easier to send, read, and manage. For composing email,
improved auto-completion of recipients helps with finding and adding frequent contacts
more quickly. For easier input of frequent text, you can now create quick responses and
store them in the app, then enter them from a convenient menu when composing. When
replying to a message, you can now toggle the message to Reply All and Forward without
changing screens.

For easier browsing across accounts and labels, the app adds an integrated menu of
accounts and recent labels. To help you locate and organize IMAP and Exchange email,
the Email app now supports nested mail subfolders, each with synchronization rules. You
can also search across folders on the server, for faster results.

For enterprises, the Email app supports EAS v14. It supports EAS certificate
authentication, provides ABQ strings for device type and mode, and allows automatic
sync to be disabled while roaming. Administrators can also limit attachment size or
disable attachments.

For keeping track of incoming email more easily, a resizable Email widget lets you
flick through recent email right from the home screen, then jump into the Email app to
compose or reply.


Android is continuously driving innovation forward, pushing the boundaries of
communication and sharing with new capabilities and interactions.

Android Beam for NFC-based sharing

Android Beam is an innovative, convenient feature for sharing across two NFC-enabled
devices, It lets people instantly exchange favorite apps, contacts, music, videos —
almost anything. It’s incredibly simple and convenient to use — there’s no menu to
open, application to launch, or pairing needed. Just touch one Android-powered phone to
another, then tap to send.

For sharing apps, Android Beam pushes a link to the app’s details page on Google Play.
On the other device, the Google Play app launches and loads the details page, for easy
downloading of the app. Individual apps can build on Android Beam to add other types of
interactions, such as passing game scores, initiating a multiplayer game or chat, and

Face Unlock

Android 4.0 introduces a completely new approach to securing a device, making each
person’s device even more personal — Face Unlock is a new screen-lock option that lets
you unlock your device with your face. It takes advantage of the device front-facing
camera and state-of-the-art facial recognition technology to register a face during
setup and then to recognize it again when unlocking the device. Just hold your device
in front of your face to unlock, or use a backup PIN or pattern.

Wi-Fi Direct and Bluetooth HDP

Support for Wi-Fi Direct lets you connect directly to nearby peer devices over Wi-Fi,
for more reliable, higher-speed communication. No internet connection or tethering is
needed. Through third-party apps, you can connect to compatible devices to take
advantage of new features such as instant sharing of files, photos, or other media;
streaming video or audio from another device; or connecting to compatible printers or
other devices.

Android 4.0 also introduces built-in support for connecting to Bluetooth Health Device
Profile (HDP) devices. With support from third-party apps, you can connect to wireless
medical devices and sensors in hospitals, fitness centers, homes, and elsewhere.

Jelly Bean 4.3

Restricted profiles for tablets

You can now limit access to apps and content at home and work. For parents, this
means you can create parental controls and for retailers, you can turn their
tablet into a kiosk.

Bluetooth Smart support

Bluetooth Smart minimizes power use while measuring and transmitting data for
fitness sensors like Fitbit, Runtastic and other devices, making your phone or
tablet more power efficient.






Dial pad autocomplete

Just start touching numbers or letters and the dial pad will automatically
