Risposta originale

Ciò sta accadendo perché FusedLocationProviderApideprecato in una versione recente di Google Play Services. Puoi verificarlo qui . La guida ufficiale ora suggerisce di utilizzare FusedLocationProviderClient . Puoi trovare la guida dettagliata qui .

per esempio all'interno onCreate()o onViewCreated()creare FusedLocationProviderClientun'istanza

Kotlin

val fusedLocationClient = LocationServices.getFusedLocationProviderClient(requireContext())

e per richiedere l'ultima posizione nota tutto ciò che devi fare è chiamare

fusedLocationClient.lastLocation.addOnSuccessListener { location: Location? ->
            location?.let { it: Location ->
                // Logic to handle location object
            } ?: kotlin.run {
                // Handle Null case or Request periodic location update https://developer.android.com/training/location/receive-location-updates
            }
        }

Giava

FusedLocationProviderClient fusedLocationClient = LocationServices.getFusedLocationProviderClient(requireContext());

e

fusedLocationClient.getLastLocation().addOnSuccessListener(requireActivity(), location -> {
        if (location != null) {
            // Logic to handle location object
        } else {
            // Handle null case or Request periodic location update https://developer.android.com/training/location/receive-location-updates
        }
    });

Semplice, non è vero?

Aggiornamento importante (24 ottobre 2017):

Ieri Google ha aggiornato la sua pagina ufficiale degli sviluppatori con un avviso che dice

Continua a utilizzare la classe FusedLocationProviderApi e non migrare alla classe FusedLocationProviderClient finché non sarà disponibile la versione 12.0.0 di Google Play Services, prevista per l'inizio del 2018. L'utilizzo di FusedLocationProviderClient prima della versione 12.0.0 causa l'arresto anomalo dell'app client quando I servizi di Google Play vengono aggiornati sul dispositivo. Ci scusiamo per gli eventuali disagi causati.

Quindi penso che dovremmo continuare a utilizzare il deprecato LocationServices.FusedLocationApifino a quando Google non risolverà il problema.

Ultimo aggiornamento (21 novembre 2017):

L'avvertimento ora è sparito. Google Play Services 11.6 6 novembre 2017, nota di rilascio dice: Penso che Play Services non si arresti in modo anomalo quando si aggiorna in background. Quindi possiamo usare nuovo FusedLocationProviderClientora.

Usa questo metodo

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

In dettaglio, fare riferimento a questa risposta

Sì, è deprecato!
Ecco alcuni punti di cui avrai bisogno durante l'utilizzo del nuovo FusedLocationProviderClient .

1. importalo come import com.google.android.gms.location.FusedLocationProviderClient; 😅
2. Ho notato che stai implementando l' interfaccia LocationListener . Nel metodo mFusedLocationClient.requestLocationUpdates (), ora non accetta un LocationListener come parametro. Puoi fornire LocationCallback . Poiché si tratta di una classe astratta, non è possibile implementarla come LocationListener. Crea un metodo di callback e passalo invece di "questo" come indicato nella guida di Google . importalo comeimport com.google.android.gms.location.LocationCallback;
3. Con LocationCallback, avrai onLocationResult () invece di onLocationChanged () . Restituisce l' oggetto LocationResult invece dell'oggetto Location. Utilizzare LocationResult.getLastLocation () per ottenere la posizione più recente disponibile in questo oggetto risultato. Importa comeimport com.google.android.gms.location.LocationResult;

Sì, è stato deprecato. FusedLocationProviderClientè più facile di FusedLocationProviderApi, perché di FusedLocationProviderApisolito richiede GoogleApiClientanche, a cui dobbiamo connetterci Google Play Servicemanualmente. Se hai utilizzato in precedenza GoogleApiClient, ora GoogleApiClientnon è più necessario ( maggiori informazioni qui ).

Per ottenere l'ultima posizione, puoi utilizzare questa funzione:

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());
                    }
                }
            });

}

il problema è con la tua dichiarazione di importazione

rimuovilo

import android.location.LocationListener;

Inserisci

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

Fai in modo che la tua attività implementi LocationListener dai servizi Google, non dal sistema operativo Android, questo ha funzionato per me.

utilizzare getFusedLocationProviderClient invece LocationServices.FusedLocationApi.

Kotlin

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

Giava

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) {
                // ...
            }
        });
