AdMob - Callback Handlers are not firing (Unity 5.3.3p3 - Android)

[Michal Krlín]

Good Day, i have problems with AdMob callback handlers an im getting mad from that! :O

Callback Handlers are not firing, for example this:

 //c#
void HandleAdClosing(object sender, EventArgs args)
    {
        Cam.backgroundColor = Color.red;
        Debug.Log("HandleAdClosing event received");
    }

does nothing...

 However requesting, showing, hiding and deleting of Interstitial and Banner ads is working fine. 

Im using Unity 5.3.3p3 , Official Google Mobile Ads Unity Plugin v3.0.3, and Lunar Console plugin. 

In AndroidManifests of both plugins I repaired Min and Max SDK Version...

<uses-sdk android:minSdkVersion="9" android:targetSdkVersion="23" />

Then I followed instructions here. Im using script similar to official demo script, see below. Lunar Console is not writing any Debug log in event handlers. Tested on LG G3 (Android 6.0) and tablet Sencor ELEMENT 7Q001 (Android 4.4). Results both same, nothing fired. It must be some really stupid reason. Please help, and sorry for my english... Thanks

Hi Michal,

Am I missing something here? In your Interstitial Ad-

 // Create an interstitial.
        interstitial = new InterstitialAd(adUnitId);
        // Register for ad events.
        interstitial.OnAdLoaded += HandleInterstitialLoaded;
        interstitial.OnAdFailedToLoad += HandleInterstitialFailedToLoad;
        interstitial.OnAdOpening += HandleInterstitialOpened;
        interstitial.OnAdClosed += HandleInterstitialClosed;
        interstitial.OnAdLeavingApplication += HandleInterstitialLeftApplication;
        // Load an interstitial ad.

I do not see that you're calling HandleAdClosing. Instead you are using this on Banner Ads.  For Banner Ads, onAdClosed() would only be called if a clickthrough opens an In-App browser full screen Ad. But let us know if you are able to listen to all other callbacks.

Hi, thanks for reply. 

I modified my requests voids like this:

But sadly nothing changed.  None of the callbacks is not working...

[Veer Arjun Busani]

Hi Michal,

Your code snippet does seem to be in place. But I would ask you to try and test with the demo script that I have attached just for sanity check. It might be due to Debug.Log(). Do get back to us if this does not work for you.

[Michal Krlín]

I tried with your demo script (whitch is completly without debug logs), sadly the same results... 

[Michal Krlín]

Im attaching my entire project. You can try build and run on device, two finger swipe down will run LunarConsole.

[Veer Arjun Busani]

Hi Michal,

I have just now tested your sample project and I was successfully able to receive callbacks. I would like you to recheck the project. Make sure the sample script is attached as a component to the main camera and run. Even on the Unity Editor, you should be able to receive callbacks.

[Michal Krlín]

Thats very strange,its still not working for me. LunarConsole is still empty, do you see messages from callback handlers in LunarConsole? Is possible that i have problems with my external tools? I will try update Android SDK, JDK and JDR. 

[Veer Arjun Busani]

Hi Michal,

I would not be able provide support for any third party frameworks such as LunarConsole. I was able to receive callbacks on the default Unity Console which meant there is no issue with the Mobile Ads SDK itself.

I have attached a screenshot for the callbacks that I have received.

[Michal Krlín]

Ok, after few days i maybe finaly figured it out. It was because really stupid reason:

1) I must have unticked Development build and Script Debugging in Build Settings.

2) LunarConsole is not possible to write print() in callback voids. That confused me, however LunarConsole is not the problem why event handlers has not been fired.

Anyway, thank you for your efforts, I writed on 3 forums and you are the only person who replayed to me. :)
