加载每个设备不同错误的奖励视频广告时出现错误

Question

我试图在我的应用中显示奖励视频广告，并且每次尝试加载广告时都会直接转到“未能加载广告”方法。

对于我的手机，我得到的错误：

对于我使用的模拟器，我得到的错误：

There was a problem getting an ad response. ErrorCode: 0 

另外，我假设，这个问题是不是使用AdMob因为我已经实施了没有问题的横幅广告。我正在使用Chartboost作为冥想。

import com.google.ads.mediation.admob.AdMobAdapter;

public class Settings extends AppCompatActivity 
     implements NavigationView.OnNavigationItemSelectedListener, RewardedVideoAdListener { 

    SharedPreferences data; 
    final String filename = "Data"; 

    Button btnAds; 
    Button btnResetData; 
    Button btnHelp; 
    long adtime; 

    private RewardedVideoAd mAd; 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     Chartboost.startWithAppId(this, "I have insterted my app id here", "and my app signature here"); 
     Chartboost.onCreate(this); 

     setContentView(R.layout.activity_settings); 
     Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar); 
     setSupportActionBar(toolbar); 

     btnAds = (Button) findViewById(R.id.btnAds); 
     btnResetData = (Button) findViewById(R.id.btnResetData); 
     btnHelp = (Button) findViewById(R.id.btnHelp); 

     DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout); 
     ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(
       this, drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close); 
     drawer.setDrawerListener(toggle); 
     toggle.syncState(); 

     NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view); 
     navigationView.setNavigationItemSelectedListener(this); 

     btnAds.setText("Loading ad..."); 

     // Load an ad into the AdMob banner view. 
     AdView adView = (AdView) findViewById(R.id.adView); 
     AdRequest adRequest = new AdRequest.Builder() 
       .setRequestAgent("android_studio:ad_template").build(); 
     adView.loadAd(adRequest); 

     mAd = MobileAds.getRewardedVideoAdInstance(this); 
     mAd.setRewardedVideoAdListener(this); 
     loadRewardedVideoAd(); 
    } 
    private void loadRewardedVideoAd() { 
      mAd.loadAd("I have inserted my app unit id here", new AdRequest.Builder().build()); 
    } 
} 

我也得到了其他“奖励后，”方法和“后退”方法

Answer 1

后看起来好像你正试图初始化Chartboost SDK旁边的AdMob中介。这在我自己的项目中已经被证明是相当有问题的，因为SDK和SDK适配器不能很好地相互协作。

您只需要使用AdMob方法调用Chartboost，尝试单独初始化将导致Chartboost适配器失败。

鉴于AdMob只是在广告网络SDK中调用它们（这会导致下载资产令人厌烦），所以这有点令人讨厌，但这就是AdMob的设计方式。

省略Chartboost startwith方法并将其替换为普通AdMob方法以初始化AdMob SDK应解决此问题。
