Google Maps tracking


Hello Everyone, I am using a native google maps for my final year project. i am creating a GPS Tracking APP. I was hoping if anyone could help me with a sample to teach me how to let my arduino and GSM module communicate with the app. i want the app to directly communinate with the GSM module through GPS to give the exact location. it is a Vehicle Tracking app so as soon as you click track vehicle. The app should be able to pin point the location of the car.
Thank you
