Android：AdMob无法使用

AdMob不会显示在我的应用程序中每次我调用loadAd(..)我得到以下错误：

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：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:ads="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    xmlns:app="http://schemas.android.com/apk/res/xx.xx"
    android:id="@+id/container"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    tools:context="xx.xx.WelcomeActivity" >

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

<RelativeLayout
    android:layout_width="wrap_content"
    android:layout_height="match_parent"
    android:layout_alignParentBottom="true" >

    <com.google.android.gms.ads.AdView
        android:id="@+id/welcomeAdView"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        ads:adSize="BANNER"
        ads:adUnitId="pub-***************" />
</RelativeLayout>

</RelativeLayout>

AndroidManifest.xml中：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="xx.xx"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk
        android:minSdkVersion="14"
        android:targetSdkVersion="19" />

    <application

        android:icon="@drawable/icon"
        android:label="@string/app_name"
        android:theme="@android:style/Theme.Holo.Light" >
        <Meta-data
            android:name="com.google.android.gms.version"
            android:value="@integer/google_play_services_version" />

        <activity
            android:name="xx.xx.WelcomeActivity"
            android:label="@string/app_name"
            android:screenorientation="portrait" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        ... some more activities ...
        <activity
            android:name="com.google.android.gms.ads.AdActivity"
            android:configChanges="keyboard|keyboardHidden|orientation|screenLayout|uiMode|screenSize|smallestScreenSize" >
        </activity>
    </application>

</manifest>

解决方法

我的代码/布局没有发现任何问题.问题可以是广告单元ID.

建议您尝试创建不同的广告单元ID

希望它有效
