Question

我想在Android游戏中使用AdGob添加广告横幅，使用LibGDX和谷歌播放服务......

你能帮我解决这个错误吗？无法理解为什么它不起作用......：/

我知道这个错误意味着什么，但我真的不知道它在我的代码中链接了什么... （我是java和android dev的新手，还有法语，所以对我来说很难......＆gt;。＆lt;）

代码

@Override
public void onCreate (Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    this.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
    gameHelper.setup(this);
    RelativeLayout layout = new RelativeLayout(this);
    requestWindowFeature(Window.FEATURE_NO_TITLE);
    getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, 
                    WindowManager.LayoutParams.FLAG_FULLSCREEN);
    getWindow().clearFlags(WindowManager.LayoutParams.FLAG_FORCE_NOT_FULLSCREEN);
    View gameView = initializeForView(new TutorialLibgdxGameservices(this), false);
    AdView adView = new AdView(this);
    adView.setAdUnitId("ca-app-pub-7435783642832057/7018436522");
    adView.setAdSize(AdSize.SMART_BANNER);
    AdRequest request = new AdRequest.Builder()
    .addTestDevice(AdRequest.DEVICE_ID_EMULATOR)
    //.addTestDevice("")  // Mon téléphone est un nexus 5
    .build();
    layout.addView(gameView);
    RelativeLayout.LayoutParams adParams = 
            new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT, 
                            RelativeLayout.LayoutParams.WRAP_CONTENT);
    adParams.addRule(RelativeLayout.ALIGN_PARENT_TOP);
    adParams.addRule(RelativeLayout.ALIGN_PARENT_RIGHT);
    layout.addView(adView, adParams);
    setContentView(layout);
}

请帮忙，我不知道应该改变什么。

Answer 1

您的错误消息是：

Could not find class 'com.google.android.gms.ads.AdView', referenced from method com.louu.aimproject.MainActivity.onCreate

这意味着com.google.android.gms.ads.AdView类尚未添加到您的APK中。该课程包含在Google Play服务库中，因此请确保将其添加到您的项目中。

Android：在添加内容之前必须调用requestFeature（），错误在哪里？
