Yes, before publishing, you should remove the test mode:
AdView adView = (AdView) findViewById(R.id.ad); AdRequest adRequest = new AdRequest(); adView.loadAd(adRequest);
In onDestroy (): adView.destroy();
In the layout:
<com.google.ads.AdView android:id="@+id/ad" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentLeft="true" android:layout_alignParentRight="true" android:layout_alignParentTop="true" ads:adSize="BANNER" ads:adUnitId="@string/admob_publisher_id" ads:loadAdOnCreate="true" > </com.google.ads.AdView>
In the settings of the AdMob application, select this: Disable test mode for all requests
