更改OSMDROID地图片段后，缓慢接收GPS位置

Question

我正在尝试创建一个应用程序，该应用程序允许我在使用OSMDROID生成的地图上查看各种事件，第一次访问该地图时，我会很快收到GPS位置，但是在切换到另一侧的选项后我实施的导航抽屉，返回到地图，我注意到我从GPS那里获得的位置非常缓慢，花费了超过15秒的时间

我尝试使用以下命令重置A-GPS数据： locationManager.sendExtraCommand ("gps," delete_aiding_data ", new Bundle ()) 但是我还没有看到任何改进，我也曾尝试对onPause，onResume函数进行各种修改，我认为这是真正的问题，但没有成功。我拥有GPS和应用程序中存档的所有权限
