You are calling startActivity from onPause() then? If you are calling startActivity and then finish(), finish() won't actually execute until the new activity you started finishes. At the moment you call startActivity on B, A's onPause will be called and B will start executing. > I thought > to my self: If I know that the user is logged in I can call finish() > in the onCreate() of Activty A. >From the rest of your description I'm also not clear if your code is the same when you started your question as it is when you finish it.

What do you mean "nothing happens"? Something has to happen, something will be launch, even it it closes immediately. If you were in B and you press 'back' and see the home screen, then an instance of A no longer exists, because it would be behind B. My guess is what is actually happening is that when you hit 'back' from B, A is immediately finishing. When you try to launch your application from the home screen again, I'm not sure what is happening. Hopefully you can clarify exactly what you're doing.
