Ads not showing Unity Android - Initialisation Problem

[Haris M]

Hey there,

I run into an issue where I build my Unity game to android with Google Admob integrated and it does not show ads. I have used the logcat to find out that there is some sort of issue with the initialisation of the ad network. I have been struggling to find a solution to this issue and would greatly appreciate some assistance.

Here is the error that I receive in logcat:

Caused by: java.lang.ClassNotFoundException: Didn't find class "com.google.android.gms.ads.initialization.OnInitializationCompleteListener" on path: DexPathList[[zip file "/data/app/PACKAGENAME-GTuKFd6EQmpWzLn9EuZ6hw==/base.apk", zip file "/data/app/PACKAGENAME-GTuKFd6EQmpWzLn9EuZ6hw==/split_config.arm

Here is my code for the ad integration:

 void Start()
    {
        // Initialize the Google Mobile Ads SDK.
        MobileAds.Initialize(initStatus => { });

        RequestInterstitial();
        RequestRewardedVideo();


    }

 private void RequestRewardedVideo()
    {

        rewardedAd = new RewardedAd(rewardedAdUnitId);

        // Called when an ad request has successfully loaded.
        rewardedAd.OnAdLoaded += HandleRewardedAdLoaded;
        // Called when an ad request failed to load.
        rewardedAd.OnAdFailedToLoad += HandleRewardedAdFailedToLoad;
        // Called when an ad is shown.
        rewardedAd.OnAdOpening += HandleRewardedAdOpening;
        // Called when an ad request failed to show.
        rewardedAd.OnAdFailedToShow += HandleRewardedAdFailedToShow;
        // Called when the user should be rewarded for interacting with the ad.
        rewardedAd.OnUserEarnedReward += HandleUserEarnedReward;
        // Called when the ad is closed.
        rewardedAd.OnAdClosed += HandleRewardedAdClosed;

        // Create an empty ad request.
        AdRequest request = new AdRequest.Builder().Build();
        // Load the rewarded ad with the request.
        rewardedAd.LoadAd(request);
    }

    private void RequestInterstitial()
    {

        // Initialize an InterstitialAd.
        interstitial = new InterstitialAd(interstitialAdUnitId);
        // Create an empty ad request.
        AdRequest request = new AdRequest.Builder().Build();
        // Load the interstitial with the request.
        interstitial.LoadAd(request);
    }

Thanks in advance!

Hey there,

I assumed this solution was to uncheck all settings under minify as I didn't see anything to do with "proguard" in the publishing settings. So I attempted this however the build fails when I uncheck "Use R8" and "Release" under the "minify" section of the Publishing Player settings. To clarify, I press build and it starts and goes for a while before it throws me a build failure pop-up telling me that the details are in the console. It gives me multiple messages in the console.

The errors are as follows:

Error 1

Starting a Gradle Daemon, 1 incompatible and 1 stopped Daemons could not be reused, use --status for details

> Configure project :launcher
WARNING: The option setting 'android.enableR8=false' is deprecated.
It will be removed in version 5.0 of the Android Gradle plugin.
You will no longer be able to disable R8

Error 2
