Setting up an Interstitial Ad

1. To display an Interstitial ad, you need a interstitial placement ID.
2. After adding your app, select INTERSTITIAL AD to create a placement for ad type Interstitial.
3. Once you successfully create the placement, the placement ID is available.

Adding an Interstitial Ad to your App

Add the following code inside your activity's oncreate() method:

InMobiInterstitial interstitial = new InMobiInterstitial(this, placement_id, new InMobiInterstitial.InterstitialAdListener2() {
        @Override
        public void onAdRewardActionCompleted(InMobiInterstitial ad, Map rewards) {}
        @Override
        public void onAdDisplayed(InMobiInterstitial ad) {
            Log.d(TAG, "onAdDisplayed: ");
        }
        @Override
        public void onAdDismissed(InMobiInterstitial ad) {
            Log.d(TAG, "onAdDismissed: ");
        }
        @Override
        public void onAdInteraction(InMobiInterstitial ad, Map params) {}
        @Override
        public void onAdLoadSucceeded(final InMobiInterstitial ad) {
            Log.d(TAG, "onAdLoadSucceeded: ");
        }

        @Override
        public void onAdDisplayFailed(InMobiInterstitial inMobiInterstitial) {
            Log.d(TAG, "onAdDisplayFailed: ");
        }

        @Override
        public void onAdWillDisplay(InMobiInterstitial inMobiInterstitial) {
            Log.d(TAG, "onAdWillDisplay: ");
        }

        @Override
        public void onAdLoadFailed(InMobiInterstitial ad, InMobiAdRequestStatus requestStatus) {
            Log.d(TAG, "onAdLoadFailed: " + requestStatus.getMessage());
        }

        @Override
        public void onAdReceived(InMobiInterstitial inMobiInterstitial) {
            Log.d(TAG, "onAdReceived: ");
        }

        @Override
        public void onUserLeftApplication(InMobiInterstitial ad){
            Log.d(TAG, "onUserLeftApplication: ");
        }
    });
    interstitial.load();
    if(interstitial.isReady())
        interstitial.show();
