I am trying to get to the current location of the user. On running the app crashes. The map is working, it points to the default lat long i.e Sydney, But on trying to access current location app crashes. I have created the enableUserLocation method to check for permissions.
class MapsActivity : AppCompatActivity(), OnMapReadyCallback {
private lateinit var mMap: GoogleMap
private lateinit var geofencingClient: GeofencingClient
private var FINE_LOCATION_ACCESS_REQUEST_CODE = 10001
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_maps)
// Obtain the SupportMapFragment and get notified when the map is ready to be used.
val mapFragment = supportFragmentManager
.findFragmentById(R.id.map) as SupportMapFragment
mapFragment.getMapAsync(this)
geofencingClient = LocationServices.getGeofencingClient(this)
}
/**
* Manipulates the map once available.
* This callback is triggered when the map is ready to be used.
* This is where we can add markers or lines, add listeners or move the camera. In this case,
* we just add a marker near Sydney, Australia.
* If Google Play services is not installed on the device, the user will be prompted to install
* it inside the SupportMapFragment. This method will only be triggered once the user has
* installed Google Play services and returned to the app.
*/
override fun onMapReady(googleMap: GoogleMap) {
mMap = googleMap
// Add a marker in Sydney and move the camera
val sydney = LatLng(-34.0, 151.0)
mMap.addMarker(MarkerOptions().position(sydney).title("Marker in Sydney"))
mMap.moveCamera(CameraUpdateFactory.newLatLng(sydney))
enableUserLocation()
}
private fun enableUserLocation() {
if (ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION)
== PackageManager.PERMISSION_GRANTED
) {
mMap.isMyLocationEnabled = true
} else {
//Ask for permission
if (ActivityCompat.shouldShowRequestPermissionRationale(
this,
Manifest.permission.ACCESS_FINE_LOCATION
)
) {
//we need to show a user dialog that why the permission is needed and then ask for the permission
ActivityCompat.requestPermissions(
this,
arrayOf(Manifest.permission.ACCESS_FINE_LOCATION),
FINE_LOCATION_ACCESS_REQUEST_CODE
)
} else {
ActivityCompat.requestPermissions(
this,
arrayOf(Manifest.permission.ACCESS_FINE_LOCATION),
FINE_LOCATION_ACCESS_REQUEST_CODE
)
}
}
}
override fun onRequestPermissionsResult(
requestCode: Int,
permissions: Array<out String>,
grantResults: IntArray
) {
if (requestCode == FINE_LOCATION_ACCESS_REQUEST_CODE) {
if (grantResults.size > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
//We have the permission
mMap.isMyLocationEnabled = true
} else {
//we do not have the permission
}
}
}
}
Here is the logcat error which says it's a runtime exception.
