title: rewarded video ad example in libGDX
body: <p>I've been looking for an example, but didn't found it.</p>
  
  <p>I found one without libgdx and some why it didn't work, but app also didn't crash.</p>
  
  <pre><code>public class AndroidLauncher extends AndroidApplication implements AdHandler, RewardedVideoAdListener{
  
      ...
  
      RewardedVideoAd rewardedVideoAd = MobileAds.getRewardedVideoAdInstance(this);
      rewardedVideoAd.setRewardedVideoAdListener(this);
  
      rewardedSetup();
  
      private void rewardedSetup(){
          if (!rewardedVideoAd.isLoaded()){
              rewardedVideoAd.loadAd("ca-app-pub-683510441556959xxxxxxxxx", new AdRequest.Builder().build());
          }
  
          @Override
          public void onRewardedVideoAdLoaded() {
              if(rewardedVideoAd.isLoaded()){
                  rewardedVideoAd.show();
              }
          }
  
          @Override
          public void onRewarded(RewardItem rewardItem) {
              rewarded(true);
          }
      }
  }
  </code></pre>
  
  <p>And it simply don't shows, maybe it happened to anyone ? (My true code is full of handlers and stuff, thus I didn't put it all, I guess other code has 0 effect on this problem)</p>
