The Android Version is 8.1.0 The MIUI Version is MIUI 10 9.8.29

Questions:

• The location dose not work when the app runing in background after one minutes

• If only use the android.location.LocationManager,it may be add LocationManager.NETWORK_PROVIDER to help get the location data

      here is my code in `AndroidLocationProviderClient.kt`

        ......
       private var _lastLocation: Location? = null
       ......
        @SuppressLint("MissingPermission")
        override fun requestLocationUpdates(request: LocationRequestOptions) {
            client?.requestLocationUpdates(LocationManager.GPS_PROVIDER,
                    request.interval,
                    request.distanceFilter,
                    this)
            client?.requestLocationUpdates(LocationManager.NETWORK_PROVIDER,
                    request.interval,
                    request.distanceFilter,
                    this)
            if (_lastLocation == null) {
                _lastLocation = client?.getLastKnownLocation(LocationManager.GPS_PROVIDER)
                if (_lastLocation != null) {
                    onLocationChanged(_lastLocation!!)
                }
            }
        }
      ......
      override fun onLocationChanged(location: Location) {
          listener?.onLocationUpdated(LocationParserUtil.getLocationMapFromLocation(location))
          _lastLocation = location
      }
       ......

Hi @quewen08 Thank you for opening an issue;

First, I have to say that the Chinese Rom are famous for their strict battery monitoring, so before any investigation please disable the battering monitoring service or add your app to their exceptions;

by the way, Can you still see the notification after one minute?

Hi @mehdok Thank you for your reply!

I really know this ROM is very hate. So I tried to add the app to the battery whitelist, then it worked!

I forked your code and added a little functionality
