FusedLocationApi的问题，它已经被废弃了。

Posted 2021-03-19

我做了一个google地图的应用，但是当我接受权限的时候，它就关闭了。所有的代码都没问题，但onConnected方法。

这里是。

@Override
    public void onConnected(@Nullable Bundle bundle) { //La aplicacion busca la ubicación dentro de este metodo

        myLocationRequest = new LocationRequest();
        myLocationRequest.setInterval(1000); //La información de ubicación se recoge en itnervalos de 1000 milisegundos para no agotar demasiado rapido la bateria
        myLocationRequest.setFastestInterval(1000);

        myLocationRequest.setPriority(LocationRequest.PRIORITY_BALANCED_POWER_ACCURACY); //setPriority se utiliza para controlar el uso de la bateria
        if (ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED) {
            LocationServices.FusedLocationApi.requestLocationUpdates(myGoogleApiClient, myLocationRequest, this); //Busca la ubicación de locationrEquest
        }
    }

我猜是FusedLocationApi.requestLocationUpdates出了问题 因为它说那里有一个错误 而且文字是删除线。更准确的说，它说'FusedLocationapi'已经被废弃了，我不知道这是什么意思。它建议将第3个参数改为'com.google.android.gms.location.LocationListener'，但如果我这样做，应用程序就不能正常工作。如果我接受这个权限，它就会突然关闭。

我把整个代码留在这里，以防你需要检查什么。

public class MapsActivity extends FragmentActivity implements OnMapReadyCallback, GoogleApiClient.ConnectionCallbacks, GoogleApiClient.OnConnectionFailedListener, LocationListener {

    private GoogleMap mMap;
    Location myLastLocation; 
    LocationRequest myLocationRequest;
    GoogleApiClient myGoogleApiClient; 
    Marker myCurrLocationMarker; 

    @Override
    protected void onCreate(Bundle savedInstanceState) { 
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_maps);

        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
            checkLocationPermission();
        }
        SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map); 
        mapFragment.getMapAsync(this);
    }

    @Override
    public void onMapReady(GoogleMap googleMap) { 
        mMap = googleMap; 
        mMap.setMapType(GoogleMap.MAP_TYPE_NORMAL); 

        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) { 
            if (ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED) { 
                buildGoogleApiClient();
                mMap.setMyLocationEnabled(true); 
            }
        }
        else {
            buildGoogleApiClient();
            mMap.setMyLocationEnabled(true); 
        }
    }

    protected synchronized void buildGoogleApiClient(){
        myGoogleApiClient = new GoogleApiClient.Builder(this)
                .addConnectionCallbacks(this)
                .addOnConnectionFailedListener(this)
                .addApi(LocationServices.API)
                .build();
        myGoogleApiClient.connect();
    }

    @Override

        myLastLocation = location;

            myCurrLocationMarker.remove();
        }

        LatLng latLng = new LatLng(location.getLatitude(), location.getLongitude());

        MarkerOptions markerOptions = new MarkerOptions();
        markerOptions.position(latLng); 
        markerOptions.title("My Position"); 

        markerOptions.icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_MAGENTA)); 
        myCurrLocationMarker = mMap.addMarker(markerOptions); 

        mMap.moveCamera(CameraUpdateFactory.newLatLng(latLng)); 
        mMap.animateCamera(CameraUpdateFactory.zoomTo(11)); 

        if (myGoogleApiClient != null) {
            LocationServices.FusedLocationApi.removeLocationUpdates(myGoogleApiClient, this); 
        }
    }

谢谢你，如果你有什么想法，请告诉我。

答案

我认为是与导入的东西，尝试添加com.google.android.gms.location.LocationListener，像这样的MapsActivity。

public class MapsActivity extends FragmentActivity implements OnMapReadyCallback, GoogleApiClient.ConnectionCallbacks, GoogleApiClient.OnConnectionFailedListener, com.google.android.gms.location.LocationListener {
//
}
