谷歌播放服務，未發現

-1

當試圖啓動我的活動conatining的AD瀏覽我收到以下logcat的例外：谷歌播放服務，未發現

02-26 16:02:29.766: E/GooglePlayServicesUtil(26683): The Google Play services resources were not found. Check your project configuration to ensure that the resources are included.

我創建AdView的編程方式（沒有XML文件）這樣的：

public class StartActivity extends Activity { 

private AdView adView; 
    private RelativeLayout relativeLayout; 

protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_start); 
    adView = new AdView(this); 
    adView.setAdUnitId("xxx"); 
    adView.setAdSize(AdSize.SMART_BANNER); 
    relativeLayout = (RelativeLayout)findViewById(R.id.activity_start); 
    relativeLayout.addView(adView); 
    AdRequest.Builder adRequest = new AdRequest.Builder(); 
    adRequest.addTestDevice("018eb6f8"); 
    adView.loadAd(adRequest.build()); 
} 
}

這就是我包含adview的活動的樣子。

我的清單文件看起來像這樣（去除其他不相關的活動）：

<?xml version="1.0" encoding="utf-8"?>

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

<uses-sdk 
    android:minSdkVersion="16" 
    android:targetSdkVersion="19" /> 

<application 
    android:allowBackup="true" 
    android:icon="@drawable/ic_launcher" 
    android:label="@string/app_name" 
    android:theme="@style/AppTheme" > 

    <meta-data 
     android:name="com.google.android.gms.version" 
     android:value="@integer/google_play_services_version" /> 

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

，你可以看到我已經導入了谷歌播放 - 服務 - lib去日食：
