In Android an app is not automatically killed when in background. It remains in the background stack. You need to stop doing background work as soon as your app goes to background. Use the onPause/onStop methods of activity lifecycle to handle application's processing when it is in background. If you are using android services in background you can stop/unbind them to avoid unneeded battery use.
