android 2.2 to 1.6?

Question

I have been developing an android app. I had chosen 2.2 as the version. I have not used any advanced features that are specific to 2.2 or above. I want my app to work with 1.6 and above. What should I do?

Thanks.

Answer 2

Complement preview answers.

android make upward compatible your code automatically as much as possible (not always).
But lowering the api level of an app. Can be a task from simple to nightmare to execute, all depends if your code use a lot of specific 2.2 ... That's means changing API level or android.jar in your project may be far to be enough.

good luck
