android finish() method doesn't clear app from memory

Question

I have an activity and I call the finish() method and the activity is not cleared from memory.

After calling finish() , I see that the method onDestroy() is executed

Answer 1

According to this presentation from Google I/O 2008, Finish should also cause the process to be killed, but I wrote a quick application to test this and on Android 1.5 it does not.

As Romain said (who incidentally is a UI Toolkit engineer for Android), your process will just sit there doing nothing anyways, so it is nothing to worry about.
