Android 2.2 or FroYo (“Frozen Yogurt” ) has finally been unveiled by Google at their IO 2010 event, and quite some time this release had a focus on improving the core of the OS rather than improving the platform itself. With this release one of the aims had been to decrease fragmentation of the OS.
Coming back to Android 2.2, Google’s latest release: there are some major updates in Android 2.2 are which improve the performance of applications and websites on Android phones.
First of all — and best of all — FroYo introduces the new Dalvik JIT compiler for Android applications. Since Android applications are written in managed Java code, and run on a VM, with this new compiler in place, Google expects applications on Android 2.2 to get an immediate boost of as much as 2 to 5 times in running applications! This is good enough news for some of the less powerful phones, but with phones like the Nexus One, there can be some serious performance gains.
