My problem is: When I'm trying to move around in the map or zoom in & out it immediately return to my current location. Also when I search for location, new marker added at the searched location but immediately goes back to my current location. I searched for solution but found nothing.. I hope somebody can figure it out

CodePudding user response：

Its because you have move camera when your location update. You just need to put condition whether its user call or not to see current location.

Here is the line, this will alway move camera and display your current location

mMap.moveCamera(CameraUpdateFactory.newLatLngZoom(currentLocation,10));

You can do like this, whenever user required to see current location then change fromUser = true and then make to false back. Just like happen in Google Map when you click on location button.

var fromUser = false;

if(fromUser){
     mMap.moveCamera(CameraUpdateFactory.newLatLngZoom(currentLocation,10));
     fromUser = false;
}

Use this code for get current location.this method only get one time of user location.inside OnLocationResult callback handle your location logic

    private void getCurrentLocation(){

 LocationRequest locationRequest = new LocationRequest();

 FusedLocationProviderClient fusedLocationProviderClient = LocationServices.getFusedLocationProviderClient(this);

        locationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
        locationRequest.setMaxWaitTime(1000);
        locationRequest.setFastestInterval(500);
        locationRequest.setInterval(500);

        fusedLocationProviderClient.requestLocationUpdates(locationRequest, new LocationCallback() {
            @Override
            public void onLocationResult( LocationResult locationResult) {
                if(locationResult.getLocations().size() != 0){
                    Location location = locationResult.getLocations().get(0);
                    LatLng latLng = new LatLng(location.getLatitude(),location.getLongitude());
                
                    //handle current user location logic

                    FusedLocationProviderClient.removeLocationUpdates(this);

                }
            }
        }, Looper.getMainLooper());
