Android 2.2 is a minor platform release including user
features, developer features, API changes, and bug
fixes. For information on developer features and API changes, see the
Framework API section.

For developers, the Android 2.2 platform is available as a
downloadable component for the Android SDK. The downloadable platform includes a
fully compliant Android library and system image, as well as a set of emulator
skins, sample applications, and more. The downloadable platform
includes no external libraries.

To get started developing or testing against the Android
2.2 platform, use the Android SDK and AVD Manager tool to
download the platform into your SDK. For more information,
see Adding SDK
Components. If you are new to Android, download the SDK Starter Package

first.

Platform Highlights

For a list of new user features and platform highlights, see the Android
2.2 Platform Highlights document.

Revisions

The sections below provide notes about successive releases of
the Android 2.2 platform component for the Android SDK, as denoted by
revision number. To determine what revision(s) of the Android
2.2 platforms are installed in your SDK environment, refer to
the “Installed Packages” listing in the Android SDK and AVD Manager.

//

Android 2.2, Revision 1 (May 2010)

Dependencies:

Requires SDK Tools r6 or higher.

Tools:

Adds support for building with Android library projects. See SDK Tools, r6 for information.

API Level

The Android 2.2 platform delivers an updated version of
the framework API. The Android 2.2 API
is assigned an integer identifier —
8 — that is
stored in the system itself. This identifier, called the “API Level”, allows the
system to correctly determine whether an application is compatible with
the system, prior to installing the application.

To use APIs introduced in Android 2.2 in your
application, you need to set the proper value, “8″, in the

android:minSdkVersion attributes of the <uses-sdk>
element in your application’s manifest.

For more information about how to use API Level, see the API Levels document.

Framework API Changes

The sections below provide information about changes made to the application
framework API provided by the Android 2.2 platform.

App installation on external storage media

The Android platform now allows applications to request installation onto the
device’s external storage media (such as the SD card), as an alternative to
installation onto the device’s internal memory.

Application developers can express the preferred installation location for
their applications by means of a new attribute of <manifest>
in the manifest file,
android:installLocation. The attribute supports three values:

"internalOnly", "preferExternal", and
"auto". At install time, the system checks the value of
android:installLocation and installs the application
.apk according to the preferred location, if possible. If the
application has requested external installation, the system installs it into a
private, encrypted partition in the external media. Once an application .apk is
installed externally, the system lets the user change the storage location of
the .apk and move it onto the device’s internal memory if needed (and vice
versa), through Manage Applications in the user settings.

By default, the system installs all applications onto the device’s internal
memory, except for those that explicitly request external installation. This
means that the system will always install legacy applications onto internal
memory, since they do not have access to the
android:installLocation attribute. However, it is possible to
configure and compile a legacy application such that it is installed internally
on older versions of the platform and externally on Android 2.2 and later
platforms, if necessary.

Note that requesting installation onto the device’s external media is not
suitable for all applications, particularly because the external media may be
removable and unmounting/remounting may disrupt the user experience and system
settings.

For more information about setting a preferred install location for your
application, including a discussion of what types of applications should and
should not request external installation, please read the App Install Location
document.

Data backup

The platform now provides a generalized backup service that
applications can use to backup and restore user data, to ensure that users can
maintain their data when switching devices or reinstalling the application. The
Backup Manager handles the work of transporting the application data to and from
the backup storage area in the cloud. The Backup Manager can store any type of
data, from arbitrary data to files, and manages backup and restore operations
in an atomic manner. For more information, see Data Backup.

Graphics

• New OpenGL ES 2.0 APIs in android.opengl.GLES20.
• New ETC1, ETC1Util, and ETC1Util.ETC1Texture classes and utility methods for using ETC1 for texture compression.
• New ImageFormat class.
• New YUV image format API to enable compression from YUV to JPEG and manipulation of YUV data.

Media

• New APIs in android.media.AudioManager for managing audio focus, transport control, transient loss of audio focus, ducking.
• New broadcast intent for routing audio to SCO — ACTION_SCO_AUDIO_STATE_CHANGED with extras indicating new state.
• New APIs in SoundPool to detect completion of sound-loading.
• New APIs in SoundPool for auto pause and resume.
• New APIs in MediaRecorder for specifying audio settings for number of channels, encoding and sampling rates, sampling rate.
• New APIs for adding files to the media database, so that they are automatically scanned. See MediaScannerConnection.scanFile and MediaScannerConnection.OnScanCompletedListener.

Speech recognition and third-party recognition engines

• The platform provides new speech-recognition APIs that allow applications to have a richer interaction with the available voice recognizer. For example, the APIs are sufficient to integrate voice recognition deeply into an IME.
• The platform also provides a RecognitionService base class that lets third-party developers create plug-in recognition engines.
• New RecognitionListener interface to receive callbacks.
• New RecognizerIntent extras that let a requester app specify details as preferred language, minimum length in milliseconds, and so on.

Camera and camcorder

• Changes to camera preview API to improve efficieny of preview pipeline.
• New display orientation for camera (it can now work in portrait orientation).
• New APIs in android.hardware.Camera for managing zoom level.
• New APIs android.hardware.Camera.Parameters for querying and setting device camera settings such as focal length, exposure, zoom level, view angle, and others.
• New thumbnail utility for video and image thumbnails.
• New CamcorderProfile and CamcorderProfile classes enable apps to determine device hardware camera capablities.
• New support in android.media.ExifInterface for retrieving GPS and focal length.

Device policy manager

New device policy management APIs allow developers to write “device
administrator” applications that can control security features of the device,
such as the minimum password strength, data wipe, and so on. Users can select
the administrators that are enabled on their devices. For more information, see
the android.app.admin classees or the example
application code in DeviceAdminSample.java.

UI Framework

• New UI modes “car mode” and “night mode” and UiModeManager let applications adjust their application UI for specific user modes.
• New ScaleGestureDetector that lets Views detect and handle transformation gestures that involve more than one pointer (multitouch) using the supplied MotionEvents.
• Improvements in the way that multitouch events are reported in MotionEvent objects.
• The layout attribute fill_parent is renamed to match_parent. This affects both XML and Java code (see ViewGroup.LayoutParams). Note that the platform will continue to honor uses of fill_parent in legacy applications.
• New layout attributes tabStripEnabled, tabStripRight, and tabStripLeft let developers customize the bottom strip of TabWidgets.
• Better support for managed dialogs in Activity.

Accounts and sync

• New method AddPeriodicSync() lets you schedule a periodic sync with a specific account, authority, and extras at the given frequency.

New manifest elements and attributes

• For specifying the application’s preferred install location (see App Installation on External Storage Media, above):
  • New android:installLocation attribute of the <manifest> element. Specifies the default install location defined by an application.
• For managing user data backup (see Backup manager, above, for more information):
  • New android:backupAgent attribute of the
    <application> element. Specifies the component name of the
    BackupAgent subclass provided by the application to handle backup/restore
    operations, if any.
  • New android:restoreAnyVersion attribute of the
    <application> element. Boolean value that indicates whether
    the application is prepared to attempt a restore of any backed-up dataset, even
    if the backup is apparently from a newer version of the application than is
    currently installed on the device.
• For managing the platform’s JIT compiler:
  • New android:vmSafeMode attribute of the <application> element. Boolean value that specifies whether to disable JIT compiler optimizations when running the application.

Permissions

• android.permission.BIND_DEVICE_ADMIN — Any device administration broadcast receiver must require this permission, to ensure that only the system can interact with it.
• android.permission.KILL_BACKGROUND_PROCESSES — Allows an application to call killBackgroundProcesses(String).
• android.permission.BIND_WALLPAPER — Any WallpaperService must require this permission, to ensure that only the system can interact with it.
• android.permission.SET_TIME — Allows an application to set the system time.

Built-in Applications

The system image included in the downloadable platform provides these
built-in applications:

Locales

The system image included in the downloadable platform provides a variety of
built-in locales. In some cases, region-specific strings are available for the
locales. In other cases, a default version of the language is used. The
languages that are available in the Android 2.2 system
image are listed below (with language_country/region locale
descriptor).

Localized UI strings match the locales that are accessible
through Settings.

Emulator Skins

The downloadable platform includes a set of emulator skins that you can use
for modeling your application in different screen sizes and resolutions. The
emulator skins are:

• QVGA (240×320, low density, small screen)
• WQVGA (240×400, low density, normal screen)
• FWQVGA (240×432, low density, normal screen)
• HVGA (320×480, medium density, normal screen)
• WVGA800 (480×800, high density, normal screen)
• WVGA854 (480×854 high density, normal screen)
