Android versions - B4A apps working on all compatible ones?

[DeerBear]

Hello!

Imagine I create a B4A app using Android 4.0 .
However, my app uses features not specific to
Android 4 and readily available from Android 2.x
onwards.

Will it run on Android 2? If not, shall I compile a
different package for that?

Thanks.

Your app will work on Android 1.6 or above devices.

Some libraries do require a higher version. However they should specifically state it in the documentation.
