Question

My app is retaining all of the variable values when it closes and this is effecting how it runs when reopened. Is there any way to reset them all upon app close? or is there a way to clean the app from memory when it is closed so to speak? For the moment I have just been setting all of the important variables “=0” in the last few lines of execution but I know there must be a correct way to doing this.

EDIT:

OK I thought that it would just be easier to reply here instead of individually to everyone.

The app is indeed staying alive in the background, I checked with advanced task killer. How would I get the ap to “Die” by presing the back button? I think this would be the easiest solution given how the app works:

open app > press start button > press stop button > results screen > press back button to exit.

so basically each time the app runs should be an independant execution.

Answer 1

Override the onPause, onResume, and onDestroy methods. onPause should save anything upon pausing, onResume should reload these values when it is resumed, and onDestroy will be called when your app closes. You can clean up stuff in onDestroy. See this link.
