Rewarded Video Ad in Admob - Mediation not Working

Question

From my Admob, I have setup the mediation for Flurry and Vungle. When I request an Ad I am always getting the error as provided in the Logcat.

Could not instantiate mediation adapter: com.google.ads.mediation.flurry.FlurryAdapter.
MediationAdapter is not a MediationRewardedVideoAdAdapter: com.vungle.mediation.VungleInterstitialAdapter

Answer 1

The program is looking for an implementation of the MediationRewardedVideoAdAdapter which is an interface of the ad.rewards.meditation, which implements MediationAdapter.

You are using:

com.vungle.mediation.VungleInterstitialAdapter

MediationAdapter is not a MediationRewardedVideoAdAdapter: com.vungle.mediation.VungleInterstitialAdapter

Your class:

public class AndroidLauncher extends AndroidApplication 
    implements ActionResolver, GameHelper.GameHelperListener {

I'm not sure where you are implementing your adapters in your other methods that you are calling, but you said you have Interstitial working also. Seems like some confusion between using vungle and flurry. As per the vungle documentation.

compile files('libs/flurryAndroidDFPandAdMobMediationAdapter-5.0.0.r1.jar')
compile files('libs/VungleAdapter.jar')

You are using both and will need to clarify which you are using in each AdRequest.

You can initialise the AdView like so:

 AdView admobView = new AdView(this);

Instead of:

AdView admobView = createAdView();

You can add this to your line after your create AdRequest.Builder to run tests.

AdRequest.Builder.addTestDevice("B6155B00A6A175A4D29AE13C0F0FBD7B");

Also check that your have your api keys set up for flurry. This has some information for to set up a flurry adapter with AdMob, in the dashbooard, and in the code Mediate via AdMob on Android

It also shows an interesting code snippet on adding adapter extras:

FlurryAdapterExtras flurryAdapterExtras = new FlurryAdapterExtras();

AdRequest adRequest = new AdRequest.Builder()
    .addNetworkExtras(flurryAdapterExtras).build();

In part to answer the original question of the null pointer exception.

Put null checks in your onPause, onResume and onDestroy methods. It might be wise to put the initialisation within the onCreate, rather than putting it into a separate method.

It's possible your onPause method is being called for some reason before the rewardedVideoAd has been intialised. At least this way, you will get a feel if it is going to run, and it should remove that error (may provide a new one though).

The place all the following methods after your oncreate method, for readability.

@Override
protected void onPause() {
    if(rewardedVideoAd!=null)
        rewardedVideoAd.pause();
    super.onPause();
    .../...
}
@Override
protected void onResume() {
    super.onResume();
    if(rewardedVideoAd!=null)
        rewardedVideoAd.resume();
    .../...

    }
}
@Override
public void onDestroy() {
    if(rewardedVideoAd!=null)
        rewardedVideoAd.destroy();
    super.onDestroy();
    accessTokenTracker.stopTracking();
}
