环境：

runtime for android100.7

效果图：

代码：

需要去天地图官网申请token，类型为android，其中SHA1通过链接（https://blog.youkuaiyun.com/qq_29269233/article/details/53725865）中的方法进行获取，包名是android程序的包名，例如：com.example.myapplication

如果报java.lang.Exception: 密钥库文件不存在: debug.keystore的错误，则通过链接（https://blog.youkuaiyun.com/zhangxing52077/article/details/53997893）的方法来解决。
