.Gradle文件

 apply plugin: 'com.android.application'

    android {
        compileSdkVersion 23
        buildToolsVersion "23.0.0"

        defaultConfig {
            applicationId "sms.and.call.alert.flashlight.lpa.com.myapplication"
            minSdkVersion 15
            targetSdkVersion 23
            versionCode 1
            versionName "1.0"
        }
        buildTypes {
            release {
                minifyEnabled false
                proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
            }
        }
    }

    dependencies {
        compile fileTree(dir: 'libs', include: ['*.jar'])
        testCompile 'junit:junit:4.12'
        compile 'com.google.android.gms:play-services:9.6.0'

        compile 'com.google.firebase:firebase-ads:9.6.0'
    }

这是主要活动

  public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        MobileAds.initialize(getApplicationContext(), "ca-app-pub-3940256099942544~3347511713");
        AdView mAdView = (AdView) findViewById(R.id.adView);
        AdRequest request = new AdRequest.Builder()
                .addTestDevice(AdRequest.DEVICE_ID_EMULATOR)        // All emulators
                  // An example device ID
                .build();
        mAdView.loadAd(request);

    }
}
