Android-在活动上调用finish（）不会阻止其运行

Question

So I've looked up similar problems to this, and have followed the advice in those threads, but it seems to give me no change in behavior.

So I'm writing an app that essentially notifies the user when they're going too fast or too slow based on GPS onLocationChanged() calls. I overrided the onBackPressed() method to finish() and return but the activity continues to run in the background when I go back to the main activity.

To be clear, I DO want the activity to run when the app is minimized or screen is off. I only want it to stop when the user goes back to the menu (IE, hits the back button)

Here's the link to the class on pastebin: http://pastebin.com/V7z5c3HH

Thanks for your help! =D

Answer 1

Unsubscribe your location listener in the onDestroy method. However, what you need for your GPS processing is probably a Service, not an Activity.

Answer 2

You need to remove the updates for that listener.

@Override
protected void onDestroy() {
    locationManager.removeUpdates(locationListener);
    super.onDestroy();
}
