Question

我试图在应用中添加测试为 UnitId 的Admob横幅广告。但它不会加载到我的应用程序上。它附带了我添加到 onAdFailedToLoad（）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();

            }
        });

我尝试了很多解决方案，这些解决方案是我从Google搜索中获得的，但最终没有任何效果。我从 logcat 找到了这个可能的错误。

一个：

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

两个：

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

三个：

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，并且它同时具有 Google Play服务（已更新）和Google Play商店（已更新）。我还尝试了 addTestDevice（我的设备ID），但没有帮助。

Answer 1

错误1表示ID错误。

Admob给您这样的数字，它是应用ID，带有〜：

Adjustment

带/的单位ID指向请求；

ca-app-pub-9611919736642270~3440171884

应用程序ID和单位ID应该不同。您的代码中似乎相同

这是完整的官方说明：https://firebase.google.com/docs/admob/android/quick-start

您必须从admob获取单元ID并将其用于AdMob_ID

横幅广告加载失败，并在admob android上测试了广告ID
