android adMob找不到类

Question

adMob工作正常，直到我将eclipse更新到最新版本，现在开始时，报告错误java.lang.NoClassDefFoundError：com.google.ads.AdRequest。但adMob库已附加到项目中！谢谢。

public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.main); 

     AdRequest adRequest = new AdRequest(); 
     adRequest.addTestDevice(AdRequest.TEST_EMULATOR);    // Emulator 
     adRequest.addTestDevice("3xxxxxxxxxx"); 

     AdView adView = new AdView(this, AdSize.BANNER, "axxxxxxxxxx"); 

     LinearLayout layout = (LinearLayout)findViewById(R.id.mainLayout); 

     layout.addView(adView); 

     adView.loadAd(new AdRequest()); 
    } 

，并适当参考和权限上表现

<activity android:name="com.google.ads.AdActivity" 
     android:configChanges="keyboard|keyboardHidden|orientation|screenLayout|uiMode|screenSize|smallestScreenSize" /> 

<uses-permission android:name="android.permission.INTERNET" /> 
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
