Cómo solicitar permiso de ubicación en tiempo de ejecución
En el archivo de manifiesto agregué permisos gruesos y finos, y cuando ejecuto el dispositivo con Android 6, ¡no pasa nada! Intento todo pero no hay forma de obtener actualizaciones de ubicación ...
¿Qué estoy haciendo mal?
public class MainActivity extends AppCompatActivity implements LocationListener {
LocationManager locationManager;
String provider;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
provider = locationManager.getBestProvider(new Criteria(), false);
if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
// TODO: Consider calling
// ActivityCompat#requestPermissions
// here to request the missing permissions, and then overriding
// public void onRequestPermissionsResult(int requestCode, String[] permissions,
// int[] grantResults)
// to handle the case where the user grants the permission. See the documentation
// for ActivityCompat#requestPermissions for more details.
return;
}
Location location = locationManager.getLastKnownLocation(provider);
if (location != null) {
Log.i("Location Info", "Location achieved!");
} else {
Log.i("Location Info", "No location :(");
}
