一个星期以来，我一直在解决这个问题，并且无法继续进行。我只得到一张空白地图的活动。

首先，我按照谷歌地图开发者网站上的说明进行操作，但没有成功。然后我尝试从google play服务mapdemo复制一些代码，仍然失败。为了制作 SupportMapFragment，我尝试了在这里和其他网站上找到的所有内容，但没有任何帮助。

google mapdemo 本身在我的调试设备（三星 s6500）上运行良好。

谢谢

发现了问题。现在我觉得很笨。

我的包是 .mapapp，但是在 SHA-1 指纹之后，我输入它并以 .mappapp 结尾。

哦......我很高兴能克服它，但因为进入它而成为一个混蛋。

感谢任何尝试过的人。
