android studio 2: Capture latitude and longitude : i know this question is repeated question, but i didn't find a clear overview. I am using Studio 2.1 and I need below information.

I am developing a app, which capture the latitude and logitude from one mobile and send those details to Master/Server Mobile, So that server mobile will show the tracking maps on server mobile.

Here i need an over all process.
 1. I developed a background code in client mobile


After 1st step, i am confused how to move further. Do i need to create any website and capture the latitude and longitude.
OR
Do i need to follow any other steps.

Please guide me only on higher level steps.
