我的问题是由系统重置修复，但根据评论和文件，请遵循以下指南的位置权限。
感谢您的评分
参考：https://stackoverflow.com/a/66321942/9909365
后台位置权限不像其他权限那样工作。它是一个将位置权限从仅前台提升到前台和后台的请求。
用户必须有意识地选择"允许所有时间"，以便这样做，并授予后台位置权限。否则，该权限被视为拒绝。
您甚至不能请求后台位置，除非前台位置已被授予-当系统权限活动显示时，它应该已经选择了选项2或3。
See https://developer.android.com/training/location/permissions#request-background-location

• • 注：**

当您的应用使用此后台位置时，请准备一段简短的视频，演示您的应用中需要在后台访问位置的基于位置的功能（当应用未使用时）。
