Fused Location Provider - location updates by displacement not working

Question

I have an android application which will track location from background.i am using fused location api with following configuration

    mLocationRequest = new LocationRequest();
    mLocationRequest.setSmallestDisplacement(100);
    mLocationRequest.setInterval(60*1000);
    mLocationRequest.setFastestInterval(60*1000);
    mLocationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);

I need location updates only if device moves.Sometimes everything works perfectly.But sometimes i receive location updates even if device in stationary.

Why this issue happens? If i set displacement,do i need to set interval and fastest interval? Is this issue related to google play service version?

Can you show how you call the method `requestLocationUpdates` ? — Noureddine Ouertani, Jun 26 '16 at 16:36

It will update your location every 60 seconds if your mobile moves or not beaus of your give interval duration.

do you know how to get location only if device moves? – HellAmADeveloper Sep 25 '15 at 06:41
You have to use this method '@Override public void onLocationChanged(Location location) {} ' – Bhavin Sorathiya Sep 25 '15 at 06:48
But it will very sensitive. It will update location on small movement – Bhavin Sorathiya Sep 25 '15 at 06:51
i think i should get rid of time settings by set interval to max time. So if i moved i get location. I just build with this configuration. lets see what happens – HellAmADeveloper Sep 25 '15 at 07:08
i think increasing the time will cause location update to particular time. it wont help – HellAmADeveloper Sep 29 '15 at 06:19

Request your location updates using a GoogleApiClient e.g. like this and use Toasts to verify your implementation:

 if (ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED) {
    float LOCATION_REFRESH_DISTANCE = 5000;
    long LOCATION_REFRESH_TIME = 0;
    locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, LOCATION_REFRESH_TIME, LOCATION_REFRESH_DISTANCE, mlocationListener);
    mLastLocation = LocationServices.FusedLocationApi.getLastLocation(mGoogleApiClient);
    if(mLastLocation!=null){
        Toast.makeText(getApplicationContext(), "YES! mLastLocation!=null", Toast.LENGTH_SHORT).show();
        double latitude = mLastLocation.getLatitude();
        double longitude = mLastLocation.getLongitude();           
        Toast.makeText(getApplicationContext(), "Latitude = " + latitude + "\nLongitude = " + longitude, Toast.LENGTH_SHORT).show();
    }
}

Here you would be able to parametrize your Location requests with the variables LOCATION_REFRESH_DISTANCE and LOCATION_REFRESH_TIME (in milliseconds)

You would need of course the LocationListener object mLocationListener that your GoogleApiClient mGoogleApiClient needs to get the last known / current location and a Location object (I called it mLastLocation) where to store it. eg.:

private Location mLastLocation;
LocationListener mlocationListener = new LocationListener() {
@Override
public void onLocationChanged(Location location) {
    mLastLocation=location;

}

@Override
public void onStatusChanged(String s, int i, Bundle bundle) {

}

@Override
public void onProviderEnabled(String s) {

}

@Override
public void onProviderDisabled(String s) {

}
};

What you likely need is the PendingIntent version of FusedLocationProviderApi. This method is suited for the background use cases, more specifically for receiving location updates, even when the app has been killed by the system.
