How to get speed using google maps in android?

I am developing an android application which is very similar to Uber, OLA etc.

I have google maps to help the driver to navigate. Total distance is calculated from point A to B and a amount is given based on the distance travelled. The trial worked fine with just a minor 0.2 km error, which is fine!

The problem I am facing is drifting GPS and getting the speed. Drifting GPS adds unnecessary values to the distance and hence it keeps increasing. I had an idea of using :

 location.getSpeed();

from google maps API to the get the speed so that I can limit distance calculation to only when the speed is greater than 0. But the speed is always zero even if I am travelling on a vehicle, which is weird cause in reality there is actually a speed but the google maps gives me a zero speed.

Can anyone help me out in getting the speed?

It is strange tht getSpeed() function is not working, you could maybe register your location and current time on every onLocationChange call. :

LocationListener locationListener = new LocationListener() {
    public void onLocationChanged(Location location) {
         //register location and current time
    }
}

And then calculate distance between 2 location and divide it by the time between those 2 records.
