         </activity>
     </application>

 </manifest>

MainActivity.java包com.example.simplebanerad;

 import android.os.Bundle; import android.app.Activity; import
 android.view.Menu;

 public class MainActivity extends Activity { @Override
     protected void onCreate(Bundle savedInstanceState) {
         super.onCreate(savedInstanceState);
         setContentView(R.layout.activity_main);
     }


     @Override
     public boolean onCreateOptionsMenu(Menu menu) {
         // Inflate the menu; this adds items to the action bar if it is present.
         getMenuInflater().inflate(R.menu.main, menu);
         return true;
     } }

我想展示广告，但每次运行时我的应用都会崩溃。我在4.2.2 API级别17模拟器上运行它。我哪里错了？

让类com.admob.android.ads.AdView
出错

您收到此错误，因为AdView类不在com.admob.android.ads包中，而是在com.google.ads包中。

所以改变这个：

<com.admob.android.ads.AdView
         android:id="@+id/ad"
         android:layout_width="match_parent"
         android:layout_height="wrap_content"
         ads:adSize="BANNER"
         ads:adUnitId="***************"
         ads:loadAdOnCreate="true"
         ads:testDevices="TEST_EMULATOR" />

对此：

<com.google.ads.AdView
         android:id="@+id/ad"
         android:layout_width="match_parent"
         android:layout_height="wrap_content"
         ads:adSize="BANNER"
         ads:adUnitId="***************"
         ads:loadAdOnCreate="true"
         ads:testDevices="TEST_EMULATOR" />

应用程序每次运行时都会崩溃
