Android 地图未加载

我有一个简单的应用程序，可以在地图上显示设备的位置。该应用程序似乎在地图未加载的情况下工作，而是在灰色网格中工作。我做了一些记录并查看了stacktrace。它提到MapActivity无法获取连接工厂客户端。 我已经看了好几条关于这个的线索，但我找不到答案

一旦应用程序运行，它只是在onDraw和onLocationChanged之间循环，无休止。我已经创建了一个MapView apiKey，并且正确的权限也在清单中。你知道我能做什么吗？谢谢

[编辑]我也在外面走来走去，因为大楼里没有gps:）

[edit2]我还尝试重新生成不同的md5指纹以生成另一个apikey，但keytool生成相同的md5指纹。它已经存在了

[edit3]我还通过在keytool中使用不同的别名生成了不同的MD5指纹。这产生了一个不同的API密钥，不幸的是它仍然不能工作

您是否获得了调试证书的api密钥？如果不是，那就是你的问题

试着读一读这篇文章，看看你们是如何做到这一点的

keytool -list -alias androiddebugkey -keystore "c:\Users\matt\debug.keystore" -storepass android -keypass android
