Android LocationServices.FusedLocationApi obsoleto

Não consegui descobrir por que LocationServices.FusedLocationApi.requestLocationUpdates(mGoogleApiClient,mLocationRequest, this);"FusedLocationApi" foi riscado e apontei para ele dizendo que estava obsoleto. Clique aqui para ver a imagem

Resposta Original

Isso está acontecendo porque o FusedLocationProviderApiuso foi suspenso em uma versão recente dos serviços do Google Play. Você pode conferir aqui . O guia oficial agora sugere o uso de FusedLocationProviderClient . Você pode encontrar o guia detalhado aqui .

por exemplo, dentro onCreate()ou onViewCreated()crie uma FusedLocationProviderClientinstância

Kotlin

val fusedLocationClient = LocationServices.getFusedLocationProviderClient(requireContext())

e para solicitar a última localização conhecida, tudo que você precisa fazer é ligar

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());

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
        }
    });

Simples, não é?

Atualização importante (24 de outubro de 2017):

Ontem o Google atualizou sua página oficial do desenvolvedor com um aviso que diz

Continue usando a classe FusedLocationProviderApi e não migre para a classe FusedLocationProviderClient até que o Google Play Services versão 12.0.0 esteja disponível, que deve ser lançado no início de 2018. Usar o FusedLocationProviderClient antes da versão 12.0.0 faz com que o aplicativo cliente trave quando O Google Play Services é atualizado no dispositivo. Pedimos desculpas por qualquer inconveniente que isso possa ter causado.

Portanto, acho que devemos continuar usando o uso suspenso LocationServices.FusedLocationApiaté que o Google resolva o problema.

Última atualização (21 de novembro de 2017):

O aviso acabou agora. Serviços do Google Play 11.6 6 de novembro de 2017, nota de lançamento : Acho que o Play Services não travará quando for atualizado em segundo plano. Portanto, podemos usar o novo FusedLocationProviderClientagora.

Use este método

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

Em detalhes, consulte esta resposta

Sim, está obsoleto!
Aqui estão alguns pontos de que você precisará ao usar o novo FusedLocationProviderClient .

1. importá-lo como importar com.google.android.gms.location.FusedLocationProviderClient;😅
2. Percebi que você está implementando a interface LocationListener . No método mFusedLocationClient.requestLocationUpdates (), agora ele não leva um LocationListener como parâmetro. Você pode fornecer LocationCallback . Como esta é uma classe abstrata, você não pode implementá-la como LocationListener. Faça um método de retorno de chamada e passe-o em vez de 'this', conforme mencionado no guia do Google . importá-lo comoimport com.google.android.gms.location.LocationCallback;
3. Com LocationCallback, você terá onLocationResult () em vez de onLocationChanged () . Ele retorna o objeto LocationResult em vez do objeto Location. Use LocationResult.getLastLocation () para obter o local mais recente disponível neste objeto de resultado. Importar comoimport com.google.android.gms.location.LocationResult;

Sim, foi descontinuado. FusedLocationProviderClienté mais fácil do que FusedLocationProviderApi, porque FusedLocationProviderApigeralmente requer GoogleApiClienttambém, ao qual precisamos conectar Google Play Servicemanualmente. Se você usou anteriormente GoogleApiClient, agora GoogleApiClientnão é mais necessário ( mais aqui ).

Para obter a última localização, pode usar esta função:

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());
                    }
                }
            });

}

problema é com sua declaração de importação

Tire isto

import android.location.LocationListener;

adicionar

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

Faça sua atividade implementar LocationListener dos serviços do Google, não do sistema operacional Android, isso funcionou para mim.

use getFusedLocationProviderClient em vez 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) {
                // ...
            }
        });
