Answer 1

Respuesta original

Esto sucede porque FusedLocationProviderApi quedado en desuso en una versión reciente de los servicios de Google Play. Puedes consultarlo here . La guía oficial ahora sugiere usar FusedLocationProviderClient . Puede encontrar la guía detallada here .

por ejemplo, dentro de onCreate() crea una instancia de FusedLocationProviderClient

 mFusedLocationClient = LocationServices.getFusedLocationProviderClient(this);

y para solicitar la última ubicación conocida, todo lo que tiene que hacer es llamar

mFusedLocationClient.getLastLocation()
.addOnSuccessListener(this, new OnSuccessListener<Location>() {
@Override
public void onSuccess(Location location) {
// Got last known location. In some rare situations, this can be null.
if (location != null) {
// Logic to handle location object
}
}
});

¿Simple no es?

Actualización importante (24 de octubre de 2017):

Ayer Google actualizó su página oficial de desarrollador con una advertencia que dice

Continúe usando la clase FusedLocationProviderApi y no migre a la clase FusedLocationProviderClient hasta que esté disponible la versión 12.0.0 de los servicios de Google Play, que se espera que se envíe a principios de 2018. El uso de FusedLocationProviderClient antes de la versión 12.0.0 hace que la aplicación del cliente se bloquee cuando Los servicios de Google Play se actualizan en el dispositivo. Nos disculpamos por cualquier inconveniente que esto pueda haber causado.

Así que creo que deberíamos seguir usando los LocationServices.FusedLocationApi desuso hasta que Google resuelva el problema.

Última actualización (21 de noviembre de 2017):

La advertencia se ha ido ahora. Servicios de Google Play 11.6 6 de noviembre de 2017, la nota de lanzamiento dice: Creo que Play Services no se bloqueará cuando se actualice en segundo plano. Entonces podemos usar el nuevo FusedLocationProviderClient ahora.

Answer 2

Haga que su actividad implemente LocationListener desde los servicios de Google, no desde el sistema operativo Android, esto funcionó para mí.

Answer 3

Por cordura me estoy apegando a 11.2.0. No entiendo la desaprobación. A partir del 3 de noviembre de 2017, la documentación de Google hasta ahora todavía hace referencia a: LocationServices.FusedLocationApi.requestLocationUpdates(mGoogleApiClient, mLocationRequest, mListener);

Answer 4

Sí, está en desuso!
Aquí hay algunos puntos que necesitará al usar el nuevo FusedLocationProviderClient .

1. importarlo como import com.google.android.gms.location.FusedLocationProviderClient; 😅
2. Noté que está implementando la interfaz LocationListener . En el método mFusedLocationClient.requestLocationUpdates (), ahora no toma un LocationListener como parámetro. Puede proporcionar LocationCallback . Como se trata de una clase abstracta, no puede implementarla como LocationListener. Haga un método de devolución de llamada y páselo en lugar de ''esto'' como se menciona en la guide de Google. importarlo como import com.google.android.gms.location.LocationCallback;
3. Con LocationCallback, tendrás onLocationResult() lugar de onLocationChanged() . Devuelve el objeto LocationResult lugar del objeto Location. Use LocationResult.getLastLocation () para obtener la ubicación más reciente disponible en este objeto de resultado. Importarlo como import com.google.android.gms.location.LocationResult;

Answer 5

Sí, ha quedado en desuso. FusedLocationProviderClient es más fácil que FusedLocationProviderApi , porque FusedLocationProviderApi generalmente también requiere GoogleApiClient , que debemos conectar al Google Play Service manualmente. Si anteriormente usó GoogleApiClient , ahora GoogleApiClient ya no es necesario ( más aquí ).

Para obtener la última ubicación, puede usar esta función:

import com.google.android.gms.location.FusedLocationProviderClient;
import com.google.android.gms.tasks.OnCompleteListener;
public class MainActivity extends AppCompatActivity{
//before public class MainActivity extends AppCompatActivity implements LocationListener,...,...
private static final String TAG = "MainActivity";
public static final int MY_PERMISSIONS_REQUEST_FINE_LOCATION = 101;
private FusedLocationProviderClient mFusedLocationClient;
private Location mGetedLocation;
private double currentLat, currentLng;
private void getLastLocation() {
if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
requestPermissions(new String[] {Manifest.permission.ACCESS_FINE_LOCATION}, MY_PERMISSIONS_REQUEST_FINE_LOCATION);
}
return;
}
mFusedLocationClient.getLastLocation()
.addOnCompleteListener(this, new OnCompleteListener<Location>() {
@Override
public void onComplete(@NonNull Task<Location> task) {
if (task.isSuccessful() && task.getResult() != null) {
mGetedLocation = task.getResult();
currentLat = mGetedLocation.getLatitude();
currentLng = mGetedLocation.getLongitude();
//updateUI();
}else{
Log.e(TAG, "no location detected");
Log.w(TAG, "getLastLocation:exception", task.getException());
}
}
});
}

Answer 6

Usa este método

mFusedLocationClient.requestLocationUpdates(mLocationRequest, mLocationCallback, Looper.myLooper());

Answer 7

el problema es con su declaración de importación

quita esto

import android.location.LocationListener;

añadir

import com.google.android.gms.location.LocationListener;

Answer 8

use getFusedLocationProviderClient en lugar de LocationServices.FusedLocationApi.

Kotlin

activity?.let { activity ->
val client = LocationServices.getFusedLocationProviderClient(activity)
client.lastLocation.addOnCompleteListener(activity, OnCompleteListener<Location> {
// it.result.latitude
// it.result.longitude
})
}

Java

FusedLocationProviderClient client =
LocationServices.getFusedLocationProviderClient(this);
// Get the last known location
client.getLastLocation()
.addOnCompleteListener(this, new OnCompleteListener<Location>() {
@Override
public void onComplete(@NonNull Task<Location> task) {
// ...
}
});
