Android: Use FusedLocationProviderClient to get location once?

Question

With FusedLocationProviderApi being deprecated, I'm having a hard time using FusedLocationProviderClient to get location of a user just once after a button click.

Answer 1

I'm having a hard time using FusedLocationProviderClient to get location of the user just once...

FusedLocationProviderClient has the following methods

• getLastLocation() that returns a location "just once"
• requestLocationUpdates (LocationRequest request, LocationCallback callback, Looper looper)
• requestLocationUpdates (LocationRequest request, PendingIntent callbackIntent)

where LocationRequest, in its turn, has the setNumUpdates (int numUpdates) method. By passing numUpdates = 1 you'll "get location of the user just once".

Answer 2

New version of play-services-location added the method getCurrentLocation()

This is how I am getting location

AndroidManifest.xml

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />

In my Fragment

private lateinit var fusedLocationClient: FusedLocationProviderClient

Then After getting location permission code this is how I am getting location

  fusedLocationClient.getCurrentLocation(LocationRequest.PRIORITY_HIGH_ACCURACY, null)
  fusedLocationClient.lastLocation
                .addOnSuccessListener { location: Location? ->
                    // Got last known location. In some rare situations this can be null.
                    if (location != null) {
                        textView.setText(getLocationNameFromLatLon(location.latitude, location.longitude))
                    }
                }
