android - 如何解决此错误 'com.google.ads.mediation.admob.AdMobAdapter cannot be cast to com.google.android.gms.ads.mediation.m '？

Question

我在我的项目中使用 firebase 适配器，现在我为奖励广告集成了 admob 它工作正常，但完成后的每个视频都会抛出以下错误...

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

我会试试这个方法https://stackoverflow.com/a/49959522/6477998但仍然抛出这个错误。

我的gradle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'
  }

改哪个，求大佬解答，找了3天了，没改善。

提前比...

Answer 1

谢谢，这个错误会在很长时间后修复。

第 1 步: 我从 com.mopub.mobileads 中删除我的适配器类 GooglePlayServicesRewardedVideo.java(如果您使用的是 GooglePlayServicesInterstitial .java 请删除 ).

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

第 3 步:然后，删除奖励展示 Activity 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 
  }
}

第 4 步: 同步您的项目，并进行构建。它工作正常，没有错误。

谢谢。
