title: Get location of other people in Google Maps
body: <p>I'm developing an Android app that tracks a <strong>number</strong> of people through GPS with their legal consents.</p>
  
  <p>For some reason, I can't seem to find any related topics in Google or maybe I just can't construct the right words.</p>
  
  <p>Google Maps and others are already setup. I only need the approximated <code>LatLng</code>s and some basic infos from those people in-track.</p>
  
  <p>Where do I start? or any recommended links?</p>
