title: Google Maps Android API v2 creating a new LocationSource
body: <p>A <code>LocationSource</code> is defined in <a href="https://developers.google.com/maps/documentation/android/reference/com/google/android/gms/maps/LocationSource" rel="noreferrer">Google Maps Android API v2</a>.</p>
  
  <p>It is used for googlemap as the location provider. By default, the location source is provided by the gps module on the phone.</p>
  
  <p>But now I want to use a another <code>Location source</code>, the location data will be sent to android device periodically. </p>
  
  <p>I have no idea how to implement this interface. Are there any example out there? Can anyone help me with it? The document did not say anything about it. </p>
