AdMobs Banner：W / GooglePlayServicesUtil：Google Play服务缺失

Question

我使用this来实施我的AdMob横幅广告，但是我收到了错误：W / GooglePlayServicesUtil：Google Play服务缺失。

我已将以下行添加到build.gradle：

compile 'com.google.android.gms:play-services-ads:8.4.0'

这是我的onCreate()方法：

protected void onCreate（Bundle savedInstanceState）{

    super.onCreate(savedInstanceState);

    AdView adView = new AdView(this);
    adView.setAdSize(AdSize.BANNER);
    adView.setAdUnitId(testBanner);

    RelativeLayout layout = new RelativeLayout(this);
    layout.setLayoutParams(new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT));

    AdRequest adRequest = new AdRequest.Builder().build();
    adView.loadAd(adRequest);

    //fullscreen
    requestWindowFeature(Window.FEATURE_NO_TITLE);
    getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);

    //scale image
    Display display = getWindowManager().getDefaultDisplay();
    size = new Point();
    display.getSize(size);
    dispX = size.x;
    dispY = size.y;
    bg = Bitmap.createScaledBitmap(BitmapFactory.decodeResource(
            getResources(), R.drawable.bg),dispX,dispY,true);
    ls = Bitmap.createScaledBitmap(BitmapFactory.decodeResource(
            getResources(), R.drawable.losescreen),GamePanel.rescaleX(805),GamePanel.rescaleY(1105),true);
    Pb = Bitmap.createScaledBitmap(BitmapFactory.decodeResource(
            getResources(), R.drawable.playbutton),GamePanel.rescaleX(242),GamePanel.rescaleY(242),true);

    View gamePanel = new GamePanel(this);

    RelativeLayout.LayoutParams adParams =
            new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT,
                    RelativeLayout.LayoutParams.WRAP_CONTENT);
    adParams.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM);
    adParams.addRule(RelativeLayout.CENTER_HORIZONTAL);

    layout.addView(gamePanel);
    layout.addView(adView, adParams);


    mInterstitialAd = new InterstitialAd(this);
    setContentView(layout);
    contextOfApplication = getApplicationContext();

}

进入SDK管理器并下载Google Play Services，如果还没有，请Google Play Repository。

多数民众赞成。在你安装它之前，gradle中的那一行表示什么都没有。要打开SDK管理器：

安装Google Play Services后，请告诉我它是否有效。如果确实如此，请务必接受答案。如果您需要更多帮助，请随时再向我提问！

希望它有所帮助！ ： - ）
