使用FusedLocationProviderClient重新启动后，位置更新需要很长时间

编程问答 2022-08-13

问题描述

我正在使用FusedLocationProviderClient访问用户的lastLocation。如果为空，我正在等待requestLocationUpdates返回。

我已经通过重新启动设备在Pixel 3a上对其进行了测试，该操作会清除上一个位置，但是返回位置需要2分钟以上的时间。

这是我的代码。我在做什么错了？

    private fun onLocationPermissionGranted() {
        val fusedLocationProviderClient = LocationServices.getFusedLocationProviderClient(
            requireContext()
        )

        fusedLocationProviderClient.flushLocations()

        Log.i("Jamie","Attempting to access last location")

        val locationRequest = LocationRequest.create()
        locationRequest.priority = LocationRequest.PRIORITY_BALANCED_POWER_ACCURACY
        locationRequest.interval = 5000
        locationRequest.numUpdates = 1

        val callback = object : LocationCallback() {
            override fun onLocationResult(locationResult: LocationResult?) {
                Log.i("Jamie","Calling location permission granted again")
                onLocationPermissionGranted()
            }
        }

        fusedLocationProviderClient.lastLocation
            .addOnSuccessListener { location: Location? ->
                Log.i("Jamie","FusedLocation onsuccess called")
                if (location == null) {
                    Log.i("Jamie","location null")
                }

                location?.let {
                    fusedLocationProviderClient.removeLocationUpdates(callback)
                    Log.i("Jamie","Location received")
                    this.map.isMyLocationEnabled = true
                    viewmodel.currentLocation = location
                    updateCamera(location.latitude,location.longitude)
                }
            }

        fusedLocationProviderClient.requestLocationUpdates(locationRequest,callback,Looper.getMainLooper())
    }
