¿Cómo puedo mostrar la ubicación actual en un mapa de Google en Android Marshmallow?

Quiero que los mapas de google muestren la ubicación del usuario. Intenté este código, pero no funcionó en Android 6.

private GoogleMap map; LocationManager lm; LocationListener ll; Location l; LatLng pos; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.start_layout); lm = (LocationManager) this.getSystemService(Context.LOCATION_SERVICE); ll = new LocationListener() { @Override public void onLocationChanged(Location location) { l = (Location) location; } @Override public void onStatusChanged(String provider, int status, Bundle extras) {} @Override public void onProviderEnabled(String provider) {} @Override public void onProviderDisabled(String provider) {} }; SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager() .findFragmentById(R.id.nMap); mapFragment.getMapAsync(this); } @Override public void onMapReady(GoogleMap googleMap) { map = googleMap; if(ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED) { lm.requestLocationUpdates(lm.NETWORK_PROVIDER, 0, 0, ll); } pos = new LatLng(l.getLatitude(), l.getLongitude()); // Add a marker in Sydney and move the camera map.setMyLocationEnabled(true); map.addMarker(new MarkerOptions().position(pos).title("Marker in Sydney")); map.moveCamera(CameraUpdateFactory.newLatLng(pos)); } 

Aquí están los permisos que he establecido:

   

Para usar FusedLocationProviderClient con Google Play Services 11 y superior:

ver aquí: Cómo obtener la ubicación actual en GoogleMap usando FusedLocationProviderClient

Para usar (ahora obsoleto) FusedLocationProviderApi:

Si su proyecto usa los Servicios 10 de Google Play o menos, usar FusedLocationProviderApi es la mejor opción.

FusedLocationProviderApi ofrece menos consumo de batería que la antigua API de LocationManager de código abierto. Además, si ya está usando Google Play Services para Google Maps, no hay razón para no usarlo.

Aquí hay una clase de actividad completa que coloca un marcador en la ubicación actual y también mueve la cámara a la posición actual.

También comprueba el permiso de Ubicación en tiempo de ejecución para Android 6 y versiones posteriores (Marshmallow, Nougat, Oreo). Para gestionar correctamente la comprobación del tiempo de ejecución de permiso de ubicación que es necesaria en Android M / Android 6 y posterior, debe asegurarse de que el usuario haya otorgado a su aplicación el permiso Ubicación antes de llamar a mGoogleMap.setMyLocationEnabled(true) y también antes de solicitar actualizaciones de ubicación .

 public class MapLocationActivity extends AppCompatActivity implements OnMapReadyCallback, GoogleApiClient.ConnectionCallbacks, GoogleApiClient.OnConnectionFailedListener, LocationListener { GoogleMap mGoogleMap; SupportMapFragment mapFrag; LocationRequest mLocationRequest; GoogleApiClient mGoogleApiClient; Location mLastLocation; Marker mCurrLocationMarker; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); getSupportActionBar().setTitle("Map Location Activity"); mapFrag = (SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map); mapFrag.getMapAsync(this); } @Override public void onPause() { super.onPause(); //stop location updates when Activity is no longer active if (mGoogleApiClient != null) { LocationServices.FusedLocationApi.removeLocationUpdates(mGoogleApiClient, this); } } @Override public void onMapReady(GoogleMap googleMap) { mGoogleMap=googleMap; mGoogleMap.setMapType(GoogleMap.MAP_TYPE_HYBRID); //Initialize Google Play Services if (android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) { if (ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED) { //Location Permission already granted buildGoogleApiClient(); mGoogleMap.setMyLocationEnabled(true); } else { //Request Location Permission checkLocationPermission(); } } else { buildGoogleApiClient(); mGoogleMap.setMyLocationEnabled(true); } } protected synchronized void buildGoogleApiClient() { mGoogleApiClient = new GoogleApiClient.Builder(this) .addConnectionCallbacks(this) .addOnConnectionFailedListener(this) .addApi(LocationServices.API) .build(); mGoogleApiClient.connect(); } @Override public void onConnected(Bundle bundle) { mLocationRequest = new LocationRequest(); mLocationRequest.setInterval(1000); mLocationRequest.setFastestInterval(1000); mLocationRequest.setPriority(LocationRequest.PRIORITY_BALANCED_POWER_ACCURACY); if (ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED) { LocationServices.FusedLocationApi.requestLocationUpdates(mGoogleApiClient, mLocationRequest, this); } } @Override public void onConnectionSuspended(int i) {} @Override public void onConnectionFailed(ConnectionResult connectionResult) {} @Override public void onLocationChanged(Location location) { mLastLocation = location; if (mCurrLocationMarker != null) { mCurrLocationMarker.remove(); } //Place current location marker LatLng latLng = new LatLng(location.getLatitude(), location.getLongitude()); MarkerOptions markerOptions = new MarkerOptions(); markerOptions.position(latLng); markerOptions.title("Current Position"); markerOptions.icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_MAGENTA)); mCurrLocationMarker = mGoogleMap.addMarker(markerOptions); //move map camera mGoogleMap.moveCamera(CameraUpdateFactory.newLatLngZoom(latLng,11)); } public static final int MY_PERMISSIONS_REQUEST_LOCATION = 99; private void checkLocationPermission() { if (ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED) { // Should we show an explanation? if (ActivityCompat.shouldShowRequestPermissionRationale(this, Manifest.permission.ACCESS_FINE_LOCATION)) { // Show an explanation to the user *asynchronously* -- don't block // this thread waiting for the user's response! After the user // sees the explanation, try again to request the permission. new AlertDialog.Builder(this) .setTitle("Location Permission Needed") .setMessage("This app needs the Location permission, please accept to use location functionality") .setPositiveButton("OK", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialogInterface, int i) { //Prompt the user once explanation has been shown ActivityCompat.requestPermissions(MapLocationActivity.this, new String[]{Manifest.permission.ACCESS_FINE_LOCATION}, MY_PERMISSIONS_REQUEST_LOCATION ); } }) .create() .show(); } else { // No explanation needed, we can request the permission. ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.ACCESS_FINE_LOCATION}, MY_PERMISSIONS_REQUEST_LOCATION ); } } } @Override public void onRequestPermissionsResult(int requestCode, String permissions[], int[] grantResults) { switch (requestCode) { case MY_PERMISSIONS_REQUEST_LOCATION: { // If request is cancelled, the result arrays are empty. if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) { // permission was granted, yay! Do the // location-related task you need to do. if (ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED) { if (mGoogleApiClient == null) { buildGoogleApiClient(); } mGoogleMap.setMyLocationEnabled(true); } } else { // permission denied, boo! Disable the // functionality that depends on this permission. Toast.makeText(this, "permission denied", Toast.LENGTH_LONG).show(); } return; } // other 'case' lines to check for other // permissions this app might request } } } 

activity_main.xml:

     

Resultado:

De ser necesario, muestre la explicación del permiso usando un AlertDialog (esto sucede si el usuario niega una solicitud de permiso, o concede el permiso y luego lo revoca en la configuración):

enter image description here

Solicite al usuario permiso de Ubicación llamando a ActivityCompat.requestPermissions() :

Mueva la cámara a la ubicación actual y coloque Marker cuando se conceda el permiso de Ubicación:

Primero asegúrate de que tu clave API sea válida y agrégala a tu manifiesto

Aquí está la actividad de mis mapas … podría haber algo de información redundante, ya que proviene de un proyecto más grande que creé.

Hay muchos métodos aquí que son difíciles de entender, pero básicamente todos actualizan el mapa cuando está en pausa, etc. También hay tiempos de espera de conexión, etc. Lo siento por publicar esto, intenté arreglar el código, pero no pude entender qué era incorrecto.

Lo siento, pero eso es demasiada sobrecarga (arriba), corta y rápida , si tienes MapFragment, también tienes que mapear, solo haz lo siguiente:

 if (ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED) { googleMap.setMyLocationEnabled(true) } else { // Show rationale and request permission. } 

El código está en Kotlin , espero que no te importe.

que te diviertas

Por cierto, creo que este es un duplicado de: Mostrar la ubicación actual dentro de Google Map Fragment
