It's finally official. Yesterday at Google I/O, Android 2.2 (FroYo) was officially announced, as well as on the Android Developers site here. As for what is officially coming in FroYo, lets take a look at what we see from Android Developers and from what Engadget is reporting from inside I/O.

Here is a short list containing some of the major improvements according to AndroidDevelopers:

• 2-5X faster performance thanks to the Dalvik JIT compiler
• Cloud to device messaging
• Application backup
• Apps on SD cards
• Portable hotspot
• 2-3X faster Javascript rendering in the Android browser
• New Android Market features
• App error reports

Engadget reports that Google is touting that Android FroYo has "the world's fastest web browser," thanks to the Javascript engine improvements.

Adobe Flash 10.1 is still planned on being supported in FroYo as far as I know.

There is also a video on Youtube introducing Android 2.2. Have a look now, because you will be waiting awhile since we have no firm release date for 2.2 yet.
