Android LocationServices.FusedLocationApi obsolète

Je ne pouvais pas comprendre pourquoi LocationServices.FusedLocationApi.requestLocationUpdates(mGoogleApiClient,mLocationRequest, this);"FusedLocationApi" est barré et le pointer en disant qu'il est obsolète. Cliquez ici pour voir l'image

Réponse originale

Cela se produit car FusedLocationProviderApiobsolète dans une version récente des services Google Play. Vous pouvez le vérifier ici . Le guide officiel suggère maintenant d'utiliser FusedLocationProviderClient . Vous pouvez trouver le guide détaillé ici .

par exemple à l'intérieur onCreate()ou onViewCreated()créer une FusedLocationProviderClientinstance

Kotlin

val fusedLocationClient = LocationServices.getFusedLocationProviderClient(requireContext())

et pour demander le dernier emplacement connu, tout ce que vous avez à faire est d'appeler

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
            }
        }

Java

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

et

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
        }
    });

Simple, n'est-ce pas?

Mise à jour importante (24 octobre 2017):

Hier, Google a mis à jour sa page officielle de développeur avec un avertissement indiquant

Veuillez continuer à utiliser la classe FusedLocationProviderApi et ne pas migrer vers la classe FusedLocationProviderClient tant que la version 12.0.0 des services Google Play n'est pas disponible, qui devrait être livrée début 2018. L'utilisation de FusedLocationProviderClient avant la version 12.0.0 entraîne le blocage de l'application cliente lorsque Les services Google Play sont mis à jour sur l'appareil. Nous vous prions de nous excuser pour tout inconvénient que cela pourrait avoir causé.

Je pense donc que nous devrions continuer à utiliser la version obsolète LocationServices.FusedLocationApijusqu'à ce que Google résolve le problème.

Dernière mise à jour (21 novembre 2017):

L'avertissement est parti maintenant. Services Google Play 11.6 Le 6 novembre 2017, la note de publication indique: Je pense que les services Play ne planteront pas lorsqu'ils se mettront à jour en arrière-plan. Nous pouvons donc utiliser de nouvelles dès FusedLocationProviderClientmaintenant.

Utilisez cette méthode

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

En détail, référez-moi à cette réponse

Oui, c'est obsolète!
Voici quelques points dont vous aurez besoin lors de l'utilisation du nouveau FusedLocationProviderClient .

1. importez-le comme import com.google.android.gms.location.FusedLocationProviderClient;😅
2. Je remarque que vous implémentez l' interface LocationListener . Dans la méthode mFusedLocationClient.requestLocationUpdates (), elle ne prend désormais plus de LocationListener comme paramètre. Vous pouvez fournir LocationCallback . Comme il s'agit d'une classe abstraite, vous ne pouvez pas l'implémenter comme LocationListener. Faites une méthode de rappel et transmettez-la au lieu de «ceci» comme mentionné dans le guide de Google . importez-le commeimport com.google.android.gms.location.LocationCallback;
3. Avec LocationCallback, vous aurez onLocationResult () au lieu de onLocationChanged () . Il renvoie l' objet LocationResult au lieu de l'objet Location. Utilisez LocationResult.getLastLocation () pour obtenir l'emplacement le plus récent disponible dans cet objet de résultat. Importez-le commeimport com.google.android.gms.location.LocationResult;

Oui, il est obsolète. FusedLocationProviderClientest plus facile que FusedLocationProviderApi, car il en FusedLocationProviderApifaut généralement GoogleApiClienttrop, auquel nous devons nous connecter Google Play Servicemanuellement. Si vous avez déjà utilisé GoogleApiClient, maintenant GoogleApiClientn'est plus nécessaire ( plus ici ).

Pour obtenir le dernier emplacement, vous pouvez utiliser cette fonction:

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());
                    }
                }
            });

}

le problème vient de votre déclaration d'importation

enlève ça

import android.location.LocationListener;

ajouter

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

Veuillez faire en sorte que votre activité implémente LocationListener à partir des services Google et non du système d'exploitation Android, cela a fonctionné pour moi.

utilisez plutôt getFusedLocationProviderClient 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) {
                // ...
            }
        });
