Where the problem thanks in advance

Answer 1

i think you have just forgot to load the interstitial ad

before

    AdRequest adRequest = new AdRequest.Builder().addTestDevice(
            AdRequest.DEVICE_ID_EMULATOR).build();

after

AdRequest adRequest = new AdRequest.Builder().addTestDevice(
            AdRequest.DEVICE_ID_EMULATOR).build();
    mInterstitialAd.loadAd(adRequest);

Answer 2

You've correctly setup your InterstitialAd, but you didn't load anything to it. Your adRequest2 only loads the data for your banner ad, the mAdView.

That said, you seemingly has also correctly setup another AdRequest for your interstitial; you might just forgot to load it. So, all you need to do is to call this code:

mInterstitialAd.loadAd(adRequest);
