Can not perform this action after onSaveInstanceState on super.onBackPressed()

Question

I am displaying an interstitial ad when the user presses back to exit the application:

mInterstitialAd.setAdListener(new AdListener() {
   @Override
   public void onAdClosed() {
        onBackPressed(); //line 98
   }
});

requestNewInterstitial();

private void requestNewInterstitial() {
   AdRequest adRequest = new AdRequest.Builder().build();
   mInterstitialAd.loadAd(adRequest);
}

@Override
public void onBackPressed() {
   if (mInterstitialAd.isLoaded()) {
      mInterstitialAd.show();
   } else {
      super.onBackPressed(); //line 410
   }
}

This is the crash report I received from my users:

I understand that it is triggered when the user closes the ad, but why does it die on super.onBackPressed()?

Answer 1

You can't call onBackPressed() when your activity is paused. However, the behavior on a back press is to leave the activity. Just call finish() instead of onBackPressed().

You should make sure in your onBackPressed()'s override that the activity is going to finish. Back can be pressed for other reasons.
