我遵循这个指南在这里完美，已经穿过了这一次，但是当我在我的谷歌运行程序AVD在页面加载，但只有灰瓦出现，并没有显示出地图，它应该。

I followed this guide here perfectly and have gone through it again but when I run the program on my google avd the page loads but only grey tiles appear and it doesn't show a map which it should.

有没有人有什么想法？

感谢

我是前两天面临着同样的问题，并想出了一些相关的APK签名是怪怪的。解决的办法是设置自定义调试密钥库设置（默认为空），以相同的值在Eclipse preferences默认调试密钥库。

I was facing the same issue a couple of days ago and figured out that something related to APK signing was acting weird. The solution was to set the "Custom debug keystore" setting (empty by default) to the same value as the "Default debug keystore" in the Eclipse preferences.
