android - 横幅广告加载失败，在 admob android 上测试广告 ID

问题描述

我试图在我的应用程序中添加带有测试UnitId的 Admob 横幅广告。但它不会加载到我的应用程序上。它出现了我添加到onAdFailedToLoad()中的 Toast 消息“广告加载失败！ ” 。这是我的代码：

MainActivity.Java

public class MainActivity extends AppCompatActivity {

    private AdView mAdView;

    @Override
    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);


        // Sample AdMob app ID: ca-app-pub-3940256099942544~3347511713
        MobileAds.initialize(this, "ca-app-pub-3940256099942544~3347511713");

        mAdView = findViewById(R.id.adView);
        AdRequest adRequest = new AdRequest.Builder().build() ;

        mAdView.loadAd(adRequest);


        mAdView.setAdListener(new AdListener() {
            @Override
            public void onAdLoaded() {
                // Code to be executed when an ad finishes loading.
                Toast.makeText(MainActivity.this, "Ad loaded successfully!", Toast.LENGTH_SHORT).show();

            }

            @Override
            public void onAdFailedToLoad(int errorCode) {
                // Code to be executed when an ad request fails.
                Toast.makeText(MainActivity.this, "Ad load failed!", Toast.LENGTH_SHORT).show();
//                mAdView.setVisibility(View.GONE);
            }

            @Override
            public void onAdOpened() {
                // Code to be executed when an ad opens an overlay that
                // covers the screen.
                Toast.makeText(MainActivity.this, "Ad opens an overlay that covers the screen", Toast.LENGTH_SHORT).show();

            }

            @Override
            public void onAdLeftApplication() {
                // Code to be executed when the user has left the app.
                Toast.makeText(MainActivity.this, "User left the app", Toast.LENGTH_SHORT).show();

            }

            @Override
            public void onAdClosed() {
                // Code to be executed when the user is about to return
                // to the app after tapping on an ad.
                Toast.makeText(MainActivity.this, "Ad viewed by user!", Toast.LENGTH_SHORT).show();

            }
        });

我已经尝试了很多从谷歌搜索中获得的解决方案，但最终没有任何效果。我从logcat中发现了这个可能的错误。

一：

Unable to get advertising id: com.google.android.gms.common.GooglePlayServicesNotAvailableException: com.google.android.gms.measurement.internal.zzba.zzby

二：

V/FA: Inactivity, disconnecting from the service
V/FA: onUnbind called for intent. action: com.google.android.gms.measurement.START
V/FA: Local AppMeasurementService is shutting down

三：

W/GooglePlayServicesUtil: Google Play Store is missing.
E/FirebaseInstanceId: Google Play services missing or without correct permission.

我正在使用真实设备来测试我的应用程序，它同时具有Google Play 服务（更新）和 Google Play 商店（更新）。我也尝试过addTestDevice(My device id)，但没有帮助。
