30 | * 关于高德定位SDK的使用可以参考高德开放平台官网：https://lbs.amap.com/api/android-location-sdk/locationsummary/ 31 | *
32 | *33 | * 示例中主要展示通过自己实现ForcegroundService的方式实现. 34 | * 高德定位SDK从3.8.0开始已经开支支持直接将APSService变成前台service， 35 | * 对应的接口名称分别是： 36 | * 开启后台定位：{@link AMapLocationClient#enableBackgroundLocation(int, Notification)} 37 | * 关闭后台定位能力：{@link AMapLocationClient#disableBackgroundLocation(boolean)} 38 | * 在代码示例里已经有实现了，这个功能与使用自己实现ForcegroundService的方式使用其中一种就可以了，感兴趣的可以试试这个功能。 39 | *
