Android Studio Emulator Returning Null Location Data

Question

I'm learning Kotlin, and I'm trying to make a simple app that displays the users long/lat. Everything seems like it should be working, but the location data keeps throwing the 'null else{}' case. Below is what my code looks like.

class MainActivity : AppCompatActivity() {

val RequestPermissionCode = 1
var mLocation: Location? = null
private lateinit var fusedLocationClient: FusedLocationProviderClient

override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    setContentView(R.layout.activity_main)

    fusedLocationClient = LocationServices.getFusedLocationProviderClient(this)
    getLastLocation()
}

fun getLastLocation(){
    if(ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
        requestPermission()
    }
    else{
        fusedLocationClient.lastLocation
                .addOnSuccessListener {location: Location? ->
                    mLocation = location
                    if(location != null){
                        latitude.text = location.latitude.toString()
                        longitude.text = location.longitude.toString()
                    }
                    else{
                        latitude.text = "LOCATION_DENIED"
                        longitude.text = "LOCATION_DENIED"
                    }
                }
    }
}

private fun requestPermission(){
    ActivityCompat.requestPermissions(this, arrayOf(Manifest.permission.ACCESS_FINE_LOCATION), RequestPermissionCode)
    this.recreate()
}

}

Any help would be greatly appreciated! I'm about to start pulling my hair out, and can't find the answers on Google ):

Answer 1

Emulators I have noticed have issues with Location data, plus lastLocation is not making a location request, so there is good chance there is no location data. What you need is requestLocationUpdate method, so that it can retrieve active location of the user. Also you will have better luck on a physical device for last Location.
