          /&gt;
  
  
  
  
  &lt;/LinearLayout&gt;
  </code></pre>
  
  <p>but at the same time I get this message: </p>
  
  <pre><code>The following classes could not be instantiated:
  - com.adsdk.sdk.banner.AdView (Open Class, Show Error Log)
  See the Error Log (Window &gt; Show View) for more details.
  Tip: Use View.isInEditMode() in your custom views to skip code when shown in Eclipse

  <p>when I start the application it crashes.
  i have add in libs the AdSdk_4.1.6.jar and the mobfoxsdk-1.5.jar.
  i have add in manifest this permission </p>
  
  <pre><code> &lt;uses-permission android:name="android.permission.INTERNET" /&gt;
  &lt;uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /&gt;
  &lt;uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" /&gt;
  &lt;uses-permission android:name="android.permission.READ_PHONE_STATE"/&gt;
  </code></pre>
