另外，我在 HTTPS创建一个API项目/ 在那里我已经启用了谷歌地图Android的API V2 服务。然后，我用我获得的SHA1调试证书指纹

Also I created an API Project on https://code.google.com/apis/console/ where I have enabled the Google Maps Android API v2 service. Then I obtained my SHA1 debug certificate fingerprint using

keytool -list -v -keystore "C:\Users\my_user_name\.android\debug.keystore" -alias androiddebugkey -storepass android -keypass android

和输入的，并在API控制台的包名，拿到了API密钥，并把它放在清单（其中 my_api_key 是）。此过程我重复许多次，再生键，但具有相同的结果。

and entered that and the package name in the API console, got the API key and put it in the manifest (where my_api_key is). This procedure I repeated a number of times, regenerating the key but with the same result.

谁能帮助这个或暗示什么我可以尝试？任何帮助将大大AP preciated！

Could anyone help with this or suggest anything else I could try? Any help will be greatly appreciated!

推荐答案

发现它毕竟，关闭无线网络，我使用的设备后。看来，在调试的时候通过WiFi，还需要

Found it after all, after turning off WiFi on the device I was using. It seems that when debugging over WiFi you also need the

<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />

在清单中。还是不知道这只是我的情况下，它是一个普通的事情，但我想它应该是某个地方的文件中（它不是）。

in the manifest. Don't know if it was just my case or it's a general thing, but I guess it should be in the documentation somewhere (it's not).

所以，如果你正在读这篇文章，有类似的问题可以试着禁用WiFi或添加上述旁边的其他权限。

So if you are reading this and having similar problems try either disabling WiFi or adding the above permission alongside the others.
