AdMob的尝试连接在127.0.0.1和失败。始终闪光onFailedToReceiveAd（出现网络错误。）

包括在我的应用程序AbMob是工作得很好的仿真器，但我的设备上，我总是得到相同的：

AbMob included in my app is working just fine on emulator but on my device i always getting the same:

和这个异常不断重复。此外，它说：

and this exception constantly repeats. Also it says:

但AdMob广告请求，开始通常的方法（即没有.setTesting（真））为什么我要adRequest.addTestDevice？
再一次 - 它工作正常，在模拟器，但不符合我的设备。我想三星Galaxy角宿一与升级Froyo 2.2和HTC HD2用不同的Andr​​oid版本（2.2，2.3等，至少有5种不同的测试版本）。它只是溺水设备与虚假请求，而不会显示广告
这是为什么呢？

but admob request started in usual way (meaning there is no .setTesting(true)) Why have I to adRequest.addTestDevice?
Once again - it works fine on emulator but not with my device. I tried Samsung Galaxy Spica with froyo 2.2 and HTC HD2 with different android versions (2.2, 2.3 etc, at least 5 different versions tested). It just drowning the device with those fake requests and displays no ads
Why is that?
