无法显示 AdMob 横幅、收到错误 HTTP 响应代码：400 等

无论我做什么，我都无法显示来自 Admob 的横幅，我在两个不同的 Android 设备上进行了测试，以下是我得到的结果：

第一个设备：

I/Ads     ( 8161): Starting ad request.
I/Ads     ( 8161): Please set theme of AdActivity to @android:style/Theme.Translucent to enable transparent background interstitial ad.
I/Ads     ( 1006): CsiReporterFactory: CSI is not enabled. No CSI reporter created.

W/Ads     ( 8161): There was a problem getting an ad response. ErrorCode: 0
W/Ads     ( 8161): Failed to load ad: 0

注意：这里 onAdLoaded( ) 和 onAdFailedToLoad( ) 都没有被调用

第二台设备：

I/Ads     ( 1165): CsiReporterFactory: CSI is not enabled. No CSI reporter created.
I/Ads     ( 1165): Starting ad request.
I/Ads     ( 1165): Use AdRequest.Builder.addTestDevice("XXXXXXXXXXXXXXXXXXXXXXXXXX") to get test ads on this device.     
I/Ads     ( 1165): CsiReporterFactory: CSI is not enabled. No CSI reporter created.
W/Ads     ( 1165): There was a problem getting an ad response. ErrorCode: 2
I/Ads     ( 1165): Scheduling ad refresh 60000 milliseconds from now.
W/Ads     ( 1165): Failed to load ad: 2

My code:

protected void onCreate( Bundle icicle )
{
 super.onCreate( icicle );

m_glView = initOpenGLView( ); 

 m_adMobView = new AdView( this );
 m_adMobView.setAdSize( AdSize.SMART_BANNER );
 m_adMobView.setAdUnitId( "XXXXXXXXXXXXXXXXXX" );      <----I just replaced the ID with XXX for this example
 m_adMobView.setAdListener( new AdListener( )
  {
   public void onAdLoaded( ) 
   { 
    egNative.LogMessage( "ADMob::onAdLoaded" );
   };
   public void onAdFailedToLoad( )
   {
    egNative.LogMessage( "ADMob::onAdFailedToLoad" );
   }
  }  );

 FrameLayout layout = new FrameLayout( getApplicationContext( ) );
 layout.addView( m_glView );

 int gravity = android.view.Gravity.CENTER_HORIZONTAL | android.view.Gravity.TOP;
 FrameLayout.LayoutParams params = new FrameLayout.LayoutParams( FrameLayout.LayoutParams.WRAP_CONTENT , 
            FrameLayout.LayoutParams.WRAP_CONTENT ,  gravity );
  layout.addView( m_adMobView , params );
setContentView( layout );
}

@Override protected void onStart( )
 {
  super.onStart( );
  AdRequest.Builder ad_builder = new AdRequest.Builder( );
  m_adMobView.loadAd( ad_builder.build( ) );
 }

我正在运行最新版本的 Google Play 服务。还仔细检查了广告单元 ID，它们没有问题。测试广告单元 ID 也没有获得任何积极结果。 你们最终可以发布任何提示吗？ 先感谢您。

我有同样的问题。在我更新 AdMob 帐户中的结算和付款详细信息后，它开始为我工作。
