2. Declare an LVDOInterstitialAd instance variable in the Activity where you want to show the interstitial ad.


 private LVDOInterstitialAd mInterstitialAd;

LVDOInterstitialAd provides a listener interface, LVDOInterstitialListener, which you’ll use to stay informed about ad lifecycle events. Make sure your Activity implements LVDOInterstitialListener interface.
