Ads are loading, but not showing?
<p>My interstitial ads are successfully loading, but when I call <code>.show()</code> on them, they don't show up.</p>
<p>I have followed <a href="https://developers.google.com/admob/android/interstitial#adding_interstitial_ads_to_an_activity" rel="nofollow noreferrer">these</a> directions, and the ads load successfully, but don't show when I call <code>mInterstitialAd.show();</code>:</p>
<p><strong>In onCreate():</strong></p>
<pre><code> mInterstitialAd = new InterstitialAd(this);
    mInterstitialAd.setAdUnitId(&quot;My ID&quot;);

    mInterstitialAd.setAdListener(new AdListener() {
        @Override
        public void onAdClosed() {
            requestNewInterstitial();
            beginPlayingGame();
        }
    });
        requestNewInterstitial();
</code></pre>
<p><strong><code>requestNewInterstitial()</code>:</strong></p>
<pre><code>  private void requestNewInterstitial() {
        AdRequest adRequest = new AdRequest.Builder()
                .addTestDevice(&quot;Phone's ID&quot;)
                .build();

        mInterstitialAd.loadAd(adRequest);
    }
</code></pre>
<p><strong>HERE IS THE PROBLEM:</strong></p>
<pre><code> public void tryAgain(View v) {
        if (mInterstitialAd.isLoaded()) {

            mInterstitialAd.show();
            Log.v(TAG, &quot;LOADED in Game Over!&quot;);

        }
       else {
            beginPlayingGame();
        }

        beginPlayingGame();
    }
</code></pre>
<p>I get the log saying it is loaded in my log cat, but the ad doesn't actually show!  <strong>Why is it loading, but not showing?</strong></p>
<p>P.S. I think I actually got it to work once earlier, but it stopped working ever since then. What could be the problem?</p>
