Java – how to change the tag location when the location in Android changes

I have a mark on the map and need to change the position of the mark

This is my code:

public void onLocationChanged(Location location) {

    map.clear();
    LatLng latLng = new LatLng(location.getLatitude(), location.getLongitude());
    if (Home_Activity.this.markerob != null) {
        Home_Activity.this.markerob.remove();
        markerob.setPosition(latLng);
    }
    latitude=location.getLatitude();
    longitude=location.getLongitude();
    CameraUpdate cameraUpdate =CameraUpdateFactory.newCameraPosition(new CameraPosition.Builder().target(new LatLng(location.getLatitude(), location.getLongitude())).zoom(18.0f).build());

    MarkerOptions options = new MarkerOptions().position(latLng);
    //options.title( getAddressFromLatLng( latLng ) );

    options.icon(BitmapDescriptorFactory.fromBitmap(Bitmap.createScaledBitmap(
            BitmapFactory.decodeResource(getResources(),
                    spmain.getavatarimage()), 90, 90, false)));

    //map.addMarker(new MarkerOptions().position(latLng));
    Toast.makeText(getApplicationContext(), "lat="+latLng,Toast.LENGTH_SHORT).show();

    options.position(latLng);
    map.getUiSettings().setRotateGesturesEnabled(true);
    map.animateCamera(cameraUpdate);
    map.moveCamera(cameraUpdate);
    map.addMarker(options);


    //locationManager.removeUpdates(this);
}

I added the onlocationchanged method to get the location details, but do not move the tag to the new location

resolvent:

Check that your map is not marked (for the first time). If not, add a mark and keep the reference to the mark. For subsequent onlocationchanged calls, just update the latitude and longitude with the same reference

    Marker myMarker;
    if(myMarker == null){
       marker = map.addMarker(options);
    } 
    else {
       marker.setPosition(new LatLng(location.getLatitude(),location.getLongitude()));
    }

Hope this helps. Let me know it doesn't work. More relevant code will be released
