Get other user locations
<p>we are developing an android application for our thesis</p>

<p>my questions:</p>

<p>1) how could we make the application detect other users that are using the app?
2) how could we display the location of the users on the map?</p>

<p>Can anyone give us necessary codes?</p>

<p>we would be very thankful 
thanks :D </p>
