如何解决此错误“com.google.ads.mediation.admob.AdMobAdapter 无法转换为 com.google.android.gms.ads.mediation.m”？

Question

我在我的项目中使用 firebase 适配器，现在正在集成 admob 以获得奖励广告，它工作正常，但是每个视频完成后都会抛出以下错误...

  java.lang.ClassCastException: com.google.ads.mediation.admob.AdMobAdapter cannot be cast to com.google.android.gms.ads.mediation.m

我会尝试这个方法/sf/answers/3497166571/但仍然抛出这个错误。

我的等级是..

dependencies {
     implementation('com.mopub:mopub-sdk-interstitial:5.0.0@aar') {
     transitive = true
      }
    // For rewarded videos. This will automatically also include interstitials
     implementation('com.mopub:mopub-sdk-rewardedvideo:5.0.0@aar') {
     transitive = true
      }
     implementation 'com.google.firebase:firebase-core:16.0.0'
     implementation 'com.google.firebase:firebase-ads:15.0.1'
  }

改哪一个，请给我一个解决方案，我还找了3天，但没有任何改善。

提前谢谢...

Answer 1

谢谢，错误将在很长时间后修复。

第 1 步：GooglePlayServicesRewardedVideo.java我从中删除我的适配器类com.mopub.mobileads（如果您正在使用，GooglePlayServicesInterstitial.java请删除）。

步骤2：然后，将admob mediation sdk放入build.gradle即implementation 'com.mopub.mediation:admob:15.0.0.8'。

步骤 3：然后，删除奖励展示活动中的以下行。

public class MainActivity extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
   super.onCreate(savedInstanceState);
   MoPubRewardedVideos.initializeRewardedVideo(this);
   MoPub.onCreate(this); // remove 
   // ...
}

@Override
public void onPause() {
    super.onPause();
    MoPub.onPause(this); // remove 
}

@Override
public void onResume() {
    super.onResume();
    MoPub.onResume(this);  // remove 
}

// The following methods are required for Chartboost rewarded video mediation
@Override
public void onStart() {
    super.onStart();
    MoPub.onStart(this); // remove 
}

@Override
public void onRestart() {
    super.onRestart();
    MoPub.onRestart(this); // remove 
}

@Override
public void onStop() {
    super.onStop();
    MoPub.onStop(this); // remove 
}

@Override
public void onDestroy() {
    super.onDestroy();
    MoPub.onDestroy(this); // remove 
}

@Override
public void onBackPressed() {
    super.onBackPressed();
    MoPub.onBackPressed(this); // remove 
  }
}

步骤4 ：同步您的项目并进行构建。它工作正常，没有错误。

谢谢。
