In your Activity’s onCreate() method, using the activity context, apikey and listener, instantiate the LVDOInterstitialAd. To ensure a smooth experience, you should pre-fetch the ad as soon as your Activity is created.
mInterstitialAd = new LVDOInterstitialAd(this, mApiKey, this);
this is context,
mApiKey is your SSP API key, and
this is LVDOInterstitialListener.
Please contact Vdopia to obtain your SSP API key. You can contact us at firstname.lastname@example.org
