如何正确停止FusedLocationProviderClient？

Question

我在 Service.
中使用 FusedLocationProviderClient 我想以正确的方式 "stop" 它。

使用下面的代码好吗？

 @Override
    public void onDestroy() {
        super.onDestroy();
        // Stop Looper of FusedLocationProviderClient  
        if (locationClient != null) {
            locationClient = null;
        }
    }

其余代码

FusedLocationProviderClient locationClient;


protected void startLocationUpdates() {


        // Create the location request to start receiving updates
        mLocationRequest = new LocationRequest();
        mLocationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
        mLocationRequest.setInterval(UPDATE_INTERVAL);
        mLocationRequest.setFastestInterval(FASTEST_INTERVAL);

        // Create LocationSettingsRequest object using location request
        LocationSettingsRequest.Builder builder = new LocationSettingsRequest.Builder();
        builder.addLocationRequest(mLocationRequest);
        LocationSettingsRequest locationSettingsRequest = builder.build();

        // Check whether location settings are satisfied
        // https://developers.google.com/android/reference/com/google/android/gms/location/SettingsClient
        SettingsClient settingsClient = LocationServices.getSettingsClient(this);
        settingsClient.checkLocationSettings(locationSettingsRequest);

        // new Google API SDK v11 uses getFusedLocationProviderClient(this)
        if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {

            return;
        }

        locationClient = getFusedLocationProviderClient(this);getFusedLocationProviderClient(this).requestLocationUpdates(mLocationRequest, new LocationCallback() {
                    @Override
                    public void onLocationResult(LocationResult locationResult) {
                        // do work here
                        onLocationChanged(locationResult.getLastLocation());
                    }
                }, Looper.myLooper());
    }

Answer 1

只需在 onDestroy

中调用 removeLocationUpdates

对于 requestLocationUpdates，它说：

This call will keep the Google Play services connection active, so make sure to call removeLocationUpdates(LocationCallback) when you no longer need it, otherwise you lose the benefits of the automatic connection management.

Answer 2

只需将 onDestroy(); 更改为：

@Override
    protected void onDestroy() {
        super.onDestroy();
        if(locationclient!=null)
            locationclient.disconnect();
    }
