我正在使用GoogleFusedLocationAPI，我的应用中有2 service。我的服务是出于以下原因，名称为
A- BackGroundService（这将每2分钟跟踪一次位置）
B- TripStartedService（这将每隔10秒跟踪一次位置）
我可以启动服务和位置获得veri罚款。但是当我关闭 TripStartedService 并启动 BackGroundService 以再次检测新行程时，我会收到此异常。

我知道SOF上有很多问题，但我仍然无助所以请让我知道我在哪里做错了。我的服务类是下面的。我从stopLocationUpdates(); onDestroy()收到例外情况。任何帮助都是值得赞赏的..

这是我停止服务并重新开始服务的地方
停止和启动服务的方法
