I read all the post concering this issue and yet I wasnt able to solve it on my mechine. I allways get:

06-23 20:04:30.011: E/Google Maps Android API(6623): Failed to load map. Error contacting Google servers. This is probably an authentication issue (but could be due to network errors).

获取到地图中活动时。

when getting to the map activity.

我从蚀preferences我SHA1指纹，这是一样的，因为我一直在使用的关键工具。事情是，我有两个.android文件夹（一个在C：\用户\ user_name.android和我的Andr​​oid SDK文件夹）我删除一个用户的尝试使用它（没有成功启动我的应用程序后，现在是不是重建），所以我就只剩下我的Andr​​oid SDK文件夹中的其中之一是没有帮助多。 我需要帮助，我试过几乎所有的东西。

I got my SHA1 fingerprint from eclipse preferences and it is the same as I had using key tool. the thing is that I had two .android folders(one on C:\Users\user_name.android and on my android sdk folder) I delete the one on the user's after trying to activate my app using it (without success and now it is not recreated) so I got left only with the one under my android sdk folder which is not helping much. I need help I tried almost anything.

推荐答案

转到 https：//开头code .google.com /原料药/控制台 登录后，进入服务>谷歌地图Android的API V2和打开这个切换按钮。

Go to https://code.google.com/apis/console Once logged in, go to Services > Google Maps Android API v2 and switch on this toggle button.

小心：这是谷歌地图Android的API V2，而不是谷歌地图API第2版

Careful: it's "Google Maps Android API v2" and not "Google Maps API v2".
