body: <p>I am looking to use chartboost,vungle and adcolony with admob mediation.</p>
  
  <p>I have successfully generated ads through vungle and adcolony.But not getting ads with chardboost.</p>
  
  <pre><code>        vunglePub.init(getActivity(), "String");
  
  
  
          AdColony.configure(getActivity(), "version", "String", "String");
  
  
          MobileAds.initialize(getActivity(), "String");
          mAd = MobileAds.getRewardedVideoAdInstance(getActivity());
          FromRewardVideos();
          Bundle bundle = new Bundle();
  
  
          adRequest = new AdRequest.Builder()
              .addNetworkExtrasBundle(VungleInterstitialAdapter.class, bundle)
              .addNetworkExtrasBundle(AdColonyAdapter.class, bundle)
              .addTestDevice("device_id")
              .build();
  </code></pre>
  
  <p>And i am trying to implement ChartBoost like this - </p>
  
  <pre><code>Chartboost.startWithAppId(getActivity(),"id","signature");
      DelegateMethod();
      Chartboost.setDelegate(chartboostDelegate);
      Chartboost.onCreate(getActivity());
  
  
  
  private void AdLoad() {
      if (Chartboost.hasRewardedVideo(CBLocation.LOCATION_DEFAULT)) {
         Chartboost.showRewardedVideo(CBLocation.LOCATION_DEFAULT);
      }
      else {
          // We don't have a cached video right now, but try to get one for next time
          Chartboost.cacheRewardedVideo(CBLocation.LOCATION_DEFAULT);
  
      }
  }
  
  private void DelegateMethod() {
      chartboostDelegate = new ChartboostDelegate() {
          @Override
          public void didFailToLoadRewardedVideo(String location, CBError.CBImpressionError error) {
              super.didFailToLoadRewardedVideo(location, error);
  
              Chartboost.cacheRewardedVideo(CBLocation.LOCATION_DEFAULT);
  
  
  
          }
  
      };
  }
  </code></pre>
  
  <p>And calling adbuilder like this </p>
  
  <pre><code>Bundle bundle = new Bundle();
  
  
      adRequest = new AdRequest.Builder()
          .addNetworkExtrasBundle(ChartboostAdapter.class, bundle)
          .addTestDevice("device_id")
          .build();
  </code></pre>
  
  <p>Thanks in advance</p>
