public class MainActivity extends AppCompatActivity {

        setContentView(R.layout.activity_main);

        MobileAds.initialize(getApplicationContext(), "app_id");
        mAdView = (AdView) findViewById(R.id.adView_main);
        AdRequest adRequest = new AdRequest.Builder()
                .addTestDevice(AdRequest.DEVICE_ID_EMULATOR)

                .build();
        mAdView.loadAd(adRequest);
    }

和我的 gradle 文件（其中的一部分）： 模块

    compile 'com.google.firebase:firebase-ads:9.2.1'
}
apply plugin: 'com.google.gms.google-services'

project

dependencies {
        classpath 'com.android.tools.build:gradle:2.1.2'
        classpath 'com.google.gms:google-services:3.0.0'

我的问题是没有广告展示。我的布局顶部只有一个空白区域。我有最新的 SDK 工具、Google Play 资源等... 请帮我！

正如您在评论中所说，您使用了属性translatable= "false"。尝试删除它然后运行应用程序。可以通过代码访问，并且最终会出现广告。
