AdMob不会在我的应用中显示.每次我调用时loadAd(..)都会出现以下错误:

请求资源0x7f0b000e失败,因为它很复杂.找不到Google Play服务资源.检查项目配置以确保包含资源.获得广告响应时出现问题.ErrorCode:1

我搜索了几个小时来解决这个问题,但没有发现任何对我有用的东西!我下载了最新版本,Google Play Services并在项目首选项中将它们添加为库

这是我的代码:活动:

public class WelcomeActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        this.setContentView(R.layout.activity_welcome);

        // Look up the AdView as a resource and load a request.
        AdView adView = (AdView) this.findViewById(R.id.welcomeAdView);

        AdRequest.Builder adRequestBuilder = new AdRequest.Builder();
        adRequestBuilder.addTestDevice("************"); 
        adRequestBuilder.addTestDevice(AdRequest.DEVICE_ID_EMULATOR);
        AdRequest adRequest = adRequestBuilder.build();
        adView.loadAd(adRequest);
    }

}
