        super.onCreate（savedInstanceState）;
        的setContentView（R.layout.main）;

        AdRequest adRequest =新AdRequest（）;
        adRequest.addTestDevice（AdRequest.TEST_EMULATOR）; //模拟器
        adRequest.addTestDevice（3xxxxxxxxxx）;

        AD浏览报AD浏览报=新的AD浏览报（这一点，AdSize.BANNER，axxxxxxxxxx）;

        的LinearLayout布局=（的LinearLayout）findViewById（R.id.mainLayout）;

        layout.addView（AD浏览报）;

        adView.loadAd（新AdRequest（））;
    }

解决方案

请确保您的.jar文件的属性被检查 - > Java构建路径 - >订单和出口

adMob was working fine until I update eclipse to latest version, now when starting, an error is reported, java.lang.NoClassDefFoundError: com.google.ads.AdRequest. But adMob library is attached to the project!! Thank you.

 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());
    }

and proper reference and permissions on manifest

 <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" />

Make sure your .jar files are checked in Properties --> Java Build Path --> Order and Export.
