Confused About Fragment Lifecycle in Android - When Should I Use onPause vs onStop?
Hey folks,
I’m building an app with multiple fragments, and I’m trying to manage resources efficiently based on the fragment lifecycle. However, I’m unclear about the difference between onPause()
and onStop()
. I’m specifically wondering when to use them to release resources or pause animations.
Can someone explain the difference between these two lifecycle methods, and in what scenarios one should be preferred over the other?
@Override
public void onPause() {
super.onPause();
// I’m stopping some animations here, but should I also release resources?
}
@Override
public void onStop() {
super.onStop();
// I release other resources here. Is that correct, or should this be done in onPause?
}

- OnPause(): Called when the fragment is still visible but not in focus. Use it to pause animations, videos, or UI updates.
- onStop(): Called when the fragment is no longer visible at all. Use it to release heavy resources like camera, sensors, or background threads.
So,
Pause things in onPause().
Release resources in onStop().
