在3G

Question

我正在使用Google的FusedLocationProvider API来接收用户设备上的位置更新。当设备GPS打开/关闭时，我在PRIORITY_HIGH_ACCURACY和PRIORITY_BALANCED_POWER_ACCURACY之间切换。

//location manager for GPS events
locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
//request to FusedLocationProvider API
if(locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER))
    sendLocationRequest(createLocationRequest(LocationRequest.PRIORITY_HIGH_ACCURACY, interval2, fastestInterval2));
else if(locationManager.isProviderEnabled(LocationManager.NETWORK_PROVIDER))
    sendLocationRequest(createLocationRequest(LocationRequest.PRIORITY_BALANCED_POWER_ACCURACY, interval, fastestInterval));

问题是当我注册接收3G网络上的位置更新和Wifi＆amp;关闭GPS，然后将优先级设置为PRIORITY_BALANCED_POWER_ACCURACY，FusedLocationProvider请求RESOLUTION_REQUIRED，并启用Wifi。我想在没有wifi或GPS的3G网络上接收位置更新，即API文档中规定的100米块级精度。

我正在使用这些间隔：

private long /*BALANCED_POWER_ACCURACY*/interval=3600000, fastestInterval=300000, /*HIGH_ACCURACY*/interval2=10000, fastestInterval2=5000;

这些是相应的方法：

//creating location newRequest
private LocationRequest createLocationRequest(int priority, long interval, long fastestInterval)
{
    LocationRequest locationRequest = new LocationRequest();
    locationRequest.setInterval(interval);
    locationRequest.setFastestInterval(fastestInterval);
    locationRequest.setPriority(priority);
    return locationRequest;
}

//sending location newRequest with needed quality of service
private void sendLocationRequest(final LocationRequest locationRequest)
{
    LocationSettingsRequest.Builder builder = new LocationSettingsRequest.Builder().addLocationRequest(locationRequest);
    PendingResult<LocationSettingsResult> result = LocationServices.SettingsApi.checkLocationSettings(googleApiClient, builder.build());
    result.setResultCallback(new ResultCallback<LocationSettingsResult>() {
        @Override
        public void onResult(@NonNull LocationSettingsResult locationSettingsResult) {
            Status status = locationSettingsResult.getStatus();
            switch (status.getStatusCode()) {
                case LocationSettingsStatusCodes.SUCCESS: {
                    //requesting location updatesPendingResult<Status> statusPendingResult =
                            LocationServices.FusedLocationApi.requestLocationUpdates(googleApiClient, locationRequest, CurrLocationService.this);
                    break;
                }
                case LocationSettingsStatusCodes.RESOLUTION_REQUIRED:
                {
                    Toast.makeText(CurrLocationService.this,
                            getString(R.string.app_name)+" Error: Try using GPS/Wifi" + status.getStatusMessage() + " " + status.getStatus(), Toast.LENGTH_LONG).show();
                    stopSelf();
                    break;
                }
                case LocationSettingsStatusCodes.SETTINGS_CHANGE_UNAVAILABLE:
                {
                    Toast.makeText(CurrLocationService.this,
                            getString(R.string.app_name)+" Error: Unable to get your location updates", Toast.LENGTH_SHORT).show();
                    stopSelf();
                    break;
                }
            }
        }
    });
}
