Android 2.2 SDK available for download

Android developers rejoice! The Android 2.2 SDK is now available for you to download it and start building your apps. Here are some of the new APIs:

Apps on external storage

Applications can now request installation on the shared external storage (such as an SD card).

Media framework

Provides new APIs for audio focus, routing audio to SCO, and auto-scan of files to media database. Also provides APIs to let applications detect completion of sound loading and auto-pause and auto-resume audio playback.

Camera and Camcorder

New preview API doubles the frame rate from ~10FPS to ~20FPS. Camera now supports portrait orientation, zoom controls, access to exposure data, and a thumbnail utility. A new camcorder profile enables apps to determine device hardware capablities.

Graphics

New APIs for OpenGL ES 2.0, working with YUV image format, and ETC1 for texture compression.

Data backup

Apps can participate in data backup and restore, to ensure that users maintain their data after performing a factory reset or when switching devices.

Device policy manager

New device policy management APIs allow developers to write “device administrator” applications that can control security features on the device, such as the minimum password strength, data wipe, and so on. Users can select the administrators that are enabled on their devices.

UI framework

New “car mode” and “night mode” controls and configurations allow applications to adjust their UI for these situations. A scale gesture detector API provides improved definition of multi-touch events. Applications can now customize the bottom strip of a TabWidget.
