Answer 1

Your code seem perfect, I assume you are getting Null because there is no previous GPS value in your device. Do this,

Load the application in your device, move to open sky, run the application, wait for 2 minutes. Come back to office inside, and then execute above code

OR

Run the application in open sky..

You're specifically requesting GPS data, are you sure that it is enabled on the device you are testing on?

Have you looked into the fused location provider bundled with Google Play Services? With this provider you can immediately retrieve the last known location and request updates in a battery efficient way as multiple apps communicate with Google Play Services instead of directly with the device's sensors.
