title: How to make Android 2.2 app work in 2.1
body: <p>Hi
  I made an android app with 2.2 selected and API 8
  Now how can I make it work in 2.1?
  Is it possible to give support for 2.1 devices?
  Or I have to develop all the app again from scratch? :-(
  Hope not
  Please kindly help me out
  Thanking You
