Attach Eclipse debugger to restarted application

Question

I am testing the onsave/onrestore mthods of my android application.

To do this I phone my device and see that it kills the process and then I hang up. :) I see that it restarts the application.

Question is: how do I cause it to restart in debug mode so I can step through the restore process? Is there a way to tell it to automatically attach to the debugger when starting up?

Answer 1

Use android.os.Debug.waitForDebugger();

Basically, start via debugging. Exit out of your app. Set some break points. Enter back into your app (make sure that this line is hit, so put it in your onCreate or somewhere else) and it will re-attach to the running debugger.

Answer 2

I don't think there is a way to ensure the app restarts in debug mode. But if you are debugging your own app and don't mind adding debug code for testing you might want to add a Thread.sleep(5000) or something like this at an appropriate place in your startup methods. This should give you enough time to reconnect the debugger via the DDMS. Remove when you are done, of course ;)
