Does onBackPressed() stop the app?

Issue

Sorry for the question, that is not purely technique.

we published our app on Play Store. We used AdBuddiz advirtised provider.

Google has suspended our app, because of violating the following Ad Policy:

Interstitial ads may only be displayed inside of the app they came with. A prominent and accessible target must be made available to users in any interstitial ad so they may dismiss the ad without penalty or inadvertent click-through.

What we did in our app is to show the ad when the user is in the main Activity, and press back. The code we use is the following:

public void onBackPressed() {
   AdBuddiz.showAd(this);
   super.onBackPressed();
}

So the question is: Did our app violate the policy? The user presses is inside the app when the ad is shown. However, the android Activity lifecycle do not guarantee that after the backPress the app is not running, since it should just call finish().

We are considering to compile the Google Appel form, for recovering our app. Suggestions will be appreciated.

Solution

First of all it is a bad UX decision to show an Ad wenn the user wants to close the app.

Beside that there is a (sadly) common way to make a double back press behave as a real exit. A well known app like 9gag uses that to prevent accidental leaves.

You could to the same like this:

private boolean mAdShownOnce = false;

@Override
public void onBackPressed() {
    if (mAdshownOnce) {
        super.onBackPressed();
    } else {
        mAdShownOnce = true;
        AdBuddiz.showAd(this);
        mLastBackPressed = System.currentTimeMillis();
    }
}

Consider that the user might "learn" that he has to press three times to close the app (I think he can dismiss the ad by pressing back, right?!).
