AdMob尝试以127.0.0.1进行连接，但失败。始终触发onFailedToReceiveAd（发生网络错误。）

Question

我的应用程序中包含的AbMob在模拟器上可以正常工作，但在我的设备上我总是得到相同的结果：

并且这种例外不断地重复。它还说：

08-02 01:14:23.102: INFO/Ads(14152): onFailedToReceiveAd(A network error occurred.)
08-02 01:14:23.192: INFO/Ads(14152): To get test ads on this device, call adRequest.addTestDevice("061AC563478AB601B8B121B23C3BC875");

但是admob请求以通常的方式启动（意味着没有.setTesting（true））为什么我要adRequest.addTestDevice？
再次-在模拟器上可以正常使用，但不能在我的设备上使用。我尝试了froyo 2.2和HTC HD2的Samsung Galaxy Spica和不同的Android版本（2.2、2.3等，至少测试了5个不同的版本）。它只是用那些虚假的请求淹没了设备，却没有显示广告，
为什么？

Answer 1

您的/ etc / hosts文件已将r.admob.com重新定义为127.0.0.1-您从各种来源下载的自定义ROM都会这样做，因为ti会阻止所有广告。编辑您的/ etc / hosts文件，然后删除该条目。
