PopBackStack but keep the first fragment in android

Question

I am working on fragment transaction, and the backstack is like this:

fragA => fragB => fragC => fragD

I would like to return to f

Answer 1

You an override the onbackpressed (Mainactivity) and using the getBackStackEntryCount() of the fragment manager, you can check if its not equal to 1 and popbackstack on only that condition.

@Override
public void onBackPressed() {
  if (getSupportFragmentManager().getBackStackEntryCount() > 0) {
     if (!(getSupportFragmentManager().getBackStackEntryCount() == 1)) {
      getSupportFragmentManager().popBackStack() ;
    }
  }    
}
