java - 获得广告响应。错误代码 : 0

Question

这是我第一次设置和编写 Android 应用程序，也是我第一次设置广告，我已经用谷歌搜索和测试了近 2 天，但我似乎仍然无法让广告出现，它仍然给我错误“获取广告响应时出现问题。错误代码:0”。我已按照 here 上的指南进行操作以下是我的以下内容，请帮忙:(

MainActivity.java

package com.example.lechoonh.admob;

import android.support.v7.app.ActionBarActivity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;

import com.google.android.gms.ads.AdRequest;
import com.google.android.gms.ads.AdView;


public class MainActivity extends ActionBarActivity {

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

    AdView mAdView = (AdView) findViewById(R.id.adView);
    AdRequest adRequest = new AdRequest.Builder()
    .addTestDevice("DAE102189E22517B3A0C8A79337B74A2")
    .build();
    mAdView.loadAd(adRequest);


}

构建.gradle

apply plugin: 'com.android.application'

android {
compileSdkVersion 22
buildToolsVersion "21.1.2"

defaultConfig {
    applicationId "com.example.lechoonh.admob"
    minSdkVersion 9
    targetSdkVersion 22
    versionCode 1
    versionName "1.0"
}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}
}

好吧，事实证明我应该更新依赖项

com.google.android.gms:播放服务:7.0.0

到 com.google.android.gms:play-services:7.3.0

现在广告正确显示
