Admob广告未在真实设备上展示

Question

每当尝试使用真实广告暴民ID的广告不可见时，测试广告ID就会起作用

Answer 1

在这里检查您的adView监听器

mAdView.setAdListener(new AdListener() {
@Override
public void onAdLoaded() {
    // Code to be executed when an ad finishes loading.
}

@Override
public void onAdFailedToLoad(int errorCode) {
    // Code to be executed when an ad request fails.
     Log.d("ADMOB" , ""+errorCode);
}

@Override
public void onAdOpened() {
    // Code to be executed when an ad opens an overlay that
    // covers the screen.
}

@Override
public void onAdLeftApplication() {
    // Code to be executed when the user has left the app.
}

@Override
public void onAdClosed() {
    // Code to be executed when when the user is about to return
    // to the app after tapping on an ad.
}
});

如果错误代码为3，则表示没有广告可投放给您，但您的实施是正确的。
