我正在使用 admob sdk (6.1.0) 在我的自定义 ListFragments 顶部显示两个横幅，并在 onActivityCreated() 的每个片段中使用此代码：
LinearLayout adLayout = new LinearLayout(getActivity());
adView = new AdView(getActivity(), AdSize.SMART_BANNER, "xxxxxxxxxxxxx");
adView.loadAd(new AdRequest());
adLayout.addView(adView);
getListView().addHeaderView(adLayout);
在姜饼上的旧 LG Optimus 2X 上一切正常，但现在我在 Jelly Bean 上安装了三星 Galaxy S3，我的广告将不再显示！我收到此错误：

只有当应用程序在 WiFi 连接上首次加载添加时，我才会收到此错误。在 WiFi 上的所有其他时间它给了我这个错误：
