How to Implement draggable map like uber android, Update with change location

Question

How to implement draggable map like uber? I am using Google maps v2. Actually i got the solution referring this post and sharing my complete solution here

Answer 1

As LocationClient is deprected, I have used GoogleApiClient, Here is code for anyone who want to implement it. Just Replacing LocationClient with GoogleApiClient else is same as @Sishin's code.
