Listening to Video Ad. Finish Event in Interstitia

Question

I have an interstitial ad-id with video types only. Is it possible to listen whether the video play-back is completed to decide on some rewards for the user?

So far, AdListener has only loaded, failed, opened, left-app & closed events as described in this doc, but I need the video-play completion event.

One alternate solution(?) to me:
If the video length can be approximated / found, I can run some timer to detect the completion using the ad-closed event, but is it again possible to get the video duration?

Answer 1

You can use rewarded interstitial ads https://support.google.com/admob/answer/6373180?hl=en

or on AdClosed event award with in-app goodies

mInterstitialAd.setAdListener(new AdListener() {
    @Override
    public void onAdClosed() {
        //AdClosed now reward user with points etc
    }
});
