Cannot display AdMob banners, Received error HTTP response code: 400 etc

Question

Whatever I do I cannot display the banners from Admob, I tested on two Android different devices and here is what I get:

First device:

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): Failed to load ad: 0

Note: here neither onAdLoaded( ) nor onAdFailedToLoad( ) is getting called

Second device:

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.

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( ) );
 }

I am running the latest version of Google Play services. Also have double checked the Ad unit IDs and they're fine. Not getting any positive results with test Ad unit IDs too. Can you guys post any hints eventually? Thank you in advance.

I had same issue. It started work for me after I had updated my Billing and Payments details in AdMob Account.

So now you need to change your package of your app. on eclipse it is package="com.example" in AndroidManifest.xml file

or

on AndroidStudio applicationId "com.example" in build.gradle file
