参考入门指南：https://lbs.amap.com/api/android-location-sdk/gettingstarted
1、获取高德key
参考：https://lbs.amap.com/api/android-location-sdk/guide/create-project/get-key/
(1)、高德SDK控制台，点击我的应用
image.png
(2)、右上角点击创建应用
随便填写一个应用名称，以及选择一个应用类型，然后创建

(3)、点击添加

(4)、创建新KEY
点击如何获取，得到对应的SHA1填入即可，高德自己教程已经很详细出此处不再赘述。

2、集成高德定位功能
(1)、集成SDK
参考：https://lbs.amap.com/api/android-location-sdk/guide/create-project/android-studio-create-project
（2）、使用
自己创建了一个工具类，把定位代码放入其中
后台定位参考（实践之后发现没用，不知道是什么问题，暂时没实现后台定位的功能）：https://lbs.amap.com/api/android-location-sdk/guide/utilities/permision_8
