Differentiate between closing the app and turning the device

Issue

is it possible to tell these 2 states appart? close an app vs. turn the device into landscape/portrait. Because i won´t lose any data if the user closes the app but if he is bored and, lets say hes really bored, turns his device several times i won´t have this Safe/Load process all the time.

I´ve overwritten the on... methods to understand the android livecycle but i see no difference in behavior between turning the device and closing the activity.

im open for suggestions or a discussion.

I guess i need to explain my problem. I had the idea to safe data in the onPause method, but the problem is to differentiate between closing (where it should safe the data) and turning the device ( where it shouldn´t safe) don´t want to eat the battery.

Should i force the user to select landscape or portrait mode if he enters this special activity? or make it possible via a menu?.. i mean this would be a less smooth experiance for the user but easier for me somehow.

Solution

That should do the trick!

  @Override
protected void onDestroy() {
    super.onDestroy();
    if(isChangingConfigurations()){
        Toast.makeText(this,"got turned",Toast.LENGTH_SHORT).show();
    }else{
        Toast.makeText(this,"need to safe data",Toast.LENGTH_SHORT).show();
        //safe data
    }

}
