This is a very simple method @nityabaskar
Use an ActivityStarter and intents to open Google’s Navigator app. This link provides basic information https://groups.google.com/forum/#!msg/mitappinventortest/3d7bFyGM508/pNsqAb9hBQAJ
The link also provides more advanced options to provide route information too. This advice HOW TO use the new Map Control to plot a route on a map and post driving distance and time for that path. is useful too.
Again a different way is OpenStreetMap without the Map Component
And if you are experienced with JSON and willing to get a Google Map API, you can use the Google Directions API.
Is this what you want to do?
