java - android adMob 找不到类

Question

adMob 工作正常，直到我将 eclipse 更新到最新版本，现在启动时报告错误，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());
    }

以及 list 上的适当引用和权限

 <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" />

确保您的 .jar 文件已在属性 --> Java 构建路径 --> 订购和导出中选中。
