Hi MIT App Inventor Community,

I'm currently working on developing an extension for Admob ads, but I've run into a runtime error that I can't seem to resolve.

Error Message:

Runtime Error

Failed resolution of: Lcom/google/android/gms/ads/internal/client/zzk:

I've double-checked my code and the libraries I'm using, but I'm still not sure why this error is occurring. Has anyone encountered a similar issue or could provide some guidance on how to fix it?

Basic Code I Used to Check the Initialization:

 package com.simple.admob;

    import android.app.Activity;
    import android.content.Context;
    import androidx.annotation.*;
    import org.jetbrains.annotations.NotNull;

    import com.google.android.gms.ads.*;
    import com.google.android.gms.ads.RequestConfiguration;
    import com.google.android.gms.ads.initialization.InitializationStatus;
    import com.google.android.gms.ads.initialization.OnInitializationCompleteListener;

    import com.google.appinventor.components.annotations.SimpleFunction;
    import com.google.appinventor.components.annotations.SimpleEvent;
    import com.google.appinventor.components.runtime.AndroidNonvisibleComponent;
    import com.google.appinventor.components.runtime.ComponentContainer;
    import com.google.appinventor.components.runtime.EventDispatcher;

    public class Admob extends AndroidNonvisibleComponent {

        private Context context;
        private Activity activity;
        private boolean testMode = true;

        public Admob(ComponentContainer container) {
            super(container.$form());
            this.context = container.$context();
            this.activity = container.$context();
        }

        @SimpleFunction(description = "Initialize AdMob SDK.")
        public void InitializeSdk() {
            MobileAds.initialize(activity, new OnInitializationCompleteListener() {
                @Override
                public void onInitializationComplete(@NonNull InitializationStatus initializationStatus) {
                    SdkInitialized();
                }
            });
        }

        @SimpleEvent(description = "Event triggered when the AdMob SDK is successfully initialized.")
        public void SdkInitialized() {
            EventDispatcher.dispatchEvent(this, "SdkInitialized");
        }
    }

Any help would be greatly appreciated!

Thanks in advance.

Check if any dependency is missing. If you are testing in companion, build apk and then test.

Thank you for your suggestion! In the attached picture, I took the screenshot after testing with a built APK. Interestingly, it works fine in the companion but throws the error in the APK. You're correct that the issue is due to a missing dependency.

Could you guide me on how to identify which class or part of the dependency is missing?

Include all required dependencies with,

@UsesLibraries(libraries = "your-library.jar")

Import statement:

import com.google.appinventor.components.annotations.UsesLibraries;
