Requesting resource 0x7f0b000e Failed because it is complex. The Google
Play services resources were not found. Check your project configuration to ensure that the resources are included.
There was a problem getting an ad response. ErrorCode: 1

我搜索了几个小时解决这个问题,但没有找到任何适用于我的东西！我下载了最新版本的Google Play Services,并将其作为图书馆添加到我的项目首选项中

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);
    }

}

布局xml：

    xmlns:ads="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"

    android:layout_height="fill_parent"

.... other layout stuff .....

    android:layout_height="match_parent"
    android:layout_alignParentBottom="true" >

    <com.google.android.gms.ads.AdView

        ads:adSize="BANNER"
