Google announced Android 2.2. codenamed “Froyo (for frozen yogurt),” this seventh update to the Android platform brings some great new functionality to users (things like making your handset a portable hotspot and support for Adobe Flash within the browser), along with new tools for developers include:

  • new Dalvik JIT compiler delivers between a 2-5X performance improvement in CPU-bound
  • added Exchange capabilities such as account auto-discovery & calendar sync. Device policy management APIs allow developers to write apps that can control security features such as remote wipe, minimum password, lockscreen timeout etc.
  • added V8 JavaScript engine resulted in a 2-3X improvement in JavaScript performance
  • New data backup APIs enable apps to participate in data backup & restore, allowing an app’s last data to be restored when installed on 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 system automatically determine install location. On the native side, a new API now gives access to Skia bitmaps.
  • 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.
