我目前正在使用Google Maps API v2的应用程序。但是MapView只显示灰色背景，Google徽标和缩放按钮。Google地图只显示灰色背景，而不显示地图
下面是错误信息：
10-27 10:50:25.309: D/REQUEST(18335): Connection opened to:https://clients4.google.com/glm/mmap/api
10-27 10:50:25.309: D/REQUEST(18335): Open Connection
10-27 10:50:26.239: D/REQUEST(18335): DRD(24): 62|147
10-27 10:50:26.239: D/REQUEST(18335): Close
10-27 10:50:26.239: D/REQUEST(18335): Error processing: [email protected] not retrying
10-27 10:50:26.239: D/REQUEST(18335): Retrying: [email protected]
而另：
10-27 10:49:49.309: E/REQUEST(18335): In Error Mode
10-27 10:49:49.319: E/Google Maps Android API(18335): Failed to load map. Error contacting Google servers. This is probably an authentication issue (but could be due to network errors).
我的清单确实包含我的API密钥和不同的权限：

</manifest>
我希望有人能找到我的错。
谢谢。
请勿发布API密钥！你可以并且应该把它扔掉并生成一个新的......这就像在这里发布你的密码！ – WarrenFaith 2014-10-27 10:03:46
顺便说一下，你应该总是针对清单中的最新API级别，而不是与你的min sdk相同。 – WarrenFaith 2014-10-27 10:05:01
