Want to create google map navigation in my application - custom way

Question

I have created an application in which I am trying to show user\'s movement by animating marker position.

1. Using Google map V2.
2. Location updates using

Answer 1

For continuity, I think you need to fetch regular location updates from location client by giving location request like this.

LocationRequest request = LocationRequest.create()
                .setInterval(0).setFastestInterval(0)
                .setSmallestDisplacement(0)
                .setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);

Then for smooth animation you can follow the approach Steve Benett mentioned. here

The last case you mentioned in the comment about the path. I also had the same issue in one of my app. I tried with gps route simulator app to mock a route. then comparing my app and google map, googlemap followed the correct road path while my app's marker was moving slightly shifted from road. Then I tried some tweaks with marker. Like this

mPositionMarker = mMap.addMarker(new MarkerOptions()
                .flat(true)
                .icon(BitmapDescriptorFactory
                        .fromResource(R.drawable.positionIndicator))
                .anchor(0.5f, 0.5f)
                .position(
                        new LatLng(location.getLatitude(), location
                                .getLongitude())));

This worked for me. This positioned my marker on same location as of google map. (Depends on the accuracy of location though).

Thanks for the answer here
