onDestroy() won't get called after this.finish()

Question

I\'m wondering why the Motorola Milestone with 2.1-update1 behaves differently from the Emulator or e.g. the Nexus One. I am trying to exit my app with:

@Overrid         


        

Answer 1

You are doing it wrong. This is what the Doc says:

Note: do not count on this method being called as a place for saving data! [...] There are situations where the system will simply kill the activity's hosting process without calling this method (or any others) in it, so it should not be used to do things that are intended to remain around after the process goes away.

Answer 2

If the user exits to the home screen this does not need to mean that the app should be exited. In most of the time it will give a better user experience if the app just goes to the background. Try to rely on saveInstanceState and onPause.

Exiting a app is seen as bad practice in the android world, featuring a phone with a good system for true multitouch can get better user experience if the app keeps running after pressing the home screen.

Answer 3

You should use onSaveInstanceState, check this link.
