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.

Google Android 2.2 unveiled: up to 5X faster, new browser, new APIs, new services and Flash support


Google has just unveiled the latest version of its Android mobile OS a few minutes ago during Google I/O in California. Android 2.2 aka Froyo is packed with new enhancement and features that will make it the most feature rich mobile OS on the market in a couple of weeks when it’s finally launched:



Performance & speed:
The new Dalvik JIT compiler in Android 2.2 delivers between a 2-5X performance improvement in CPU-bound code vs. Android 2.1 according to various benchmarks.

New enterprise capabilities:We’ve added Exchange capabilities such as account auto-discovery and calendar sync. Device policy management APIs allow developers to write applications that can control security features of the device such as the remote wipe, minimum password, lockscreen timeout etc.

Faster, more powerful browser: We have brought the V8 JavaScript engine to the Android browser as part of 2.2. This has resulted in a 2-3X improvement in JavaScript performance vs. 2.1.

Rich set of new APIs and services: New data backup APIsenable apps to participate in data backup and restore, allowing an application’s last data to be restored when installed on a new or a reset device. Apps can utilize Android Cloud to Device Messaging to enable mobile alert, send to phone, and two-way push sync functionality. Developers can now declare whether their app should be installed on internal memory or an SD card. They can also let the system automatically determine the install location. On the native side, a new API now gives access to Skia bitmaps.

Additions to Android Market: Android Market provides Android Application Error Reports, a new bug reporting feature, giving developers access to crash and freeze reports from users. Developers will be able to access these reports via their account on the Android Market publisher website.

New Camera UI and Gallery:Android 2.2 will feature new on-screan camera controls and a new phot/video gallery. Gallery allows you to peek into picture stacks using a zoom gesture. Camera onscreen buttons provide easy access to a new UI for controling zoom, flash, white balance, geo-tagging, focus and exposure. Camcorder also provides an easy way to set video size/quality for MMS and YouTube. With the LED flash now enabled for the Camcorder, videos can be shot at night or in low light settings

Portable hotspot:Certain devices like the Nexus One can be turned into a portable Wi-Fi hotspot that can be shared with up to 8 devices.
You can use your Android-powered phone as a 3G connection for a Windows or Linux laptop by connecting their phone to the computer with a USB cable. The connection is then shared between the two devices.
