Question

一个星期以来，我一直坚持这个问题，而没有继续前进。我只用空白地图来获取活动。

首先，我按照google maps developers site上的说明操作，但没有成功。然后我尝试从谷歌播放服务mapdemo复制一些代码，但仍然失败。我尝试了我在这里找到的所有内容和其他网站，以便制作一个SupportMapFragment，但没有任何帮助。

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

感谢

Answer 1

发现问题。现在我感到愚蠢。

我的包是.mapapp，但是在SHA-1指纹之后我输入了.mappapp。

哦......我很高兴能够克服它，但因为接触它而成为一个混蛋。

感谢无论谁尝试过。
