title: Android Admob Mediation : How can i listen for interstitial ad events when using mediation?
body: <p>I have searched the whole internet and didn't find any answer. Maybe someone in this community knows the answer. Here's what is happening...</p>
  <p>When i normally use admob interstitial ad i can listen for ad events using the <code>adListener</code> like this,</p>
  <pre><code>mInterstitialAd.adListener = object : AdListener() {
          override fun onAdLoaded()  }
  
          override fun onAdFailedToLoad(adError: LoadAdError) {}
  
          override fun onAdOpened() {}
  
          override fun onAdClicked() {}
  
          override fun onAdLeftApplication() {}
  
          override fun onAdClosed()  }
      }
  </code></pre>
  <p>But i don't know if it will work the same way or not when i use multiple ad networks through Admob Mediation. In my case i am using <code>UnityAds</code> and <code>Facebook Audience Network</code> with <code>AdMob</code>. Before i was using these ad networks separately and i have used different <code>adListeners</code> for each ad network's interstitial ad.
  Now my question is, Do i need to use different <code>adListeners</code> for each of these ad networks when using <code>mediation</code>? If so, how can i do that?</p>
