title: Android how to clustering markers on map v2
body: <p>I am writing an apps about google map v2
  i have around 6000 makers to add into the map,
  and to hide and show them with the camera change,
  and also on info window click event include.</p>
  
  <p>I have done the above functions, but i have no idea on how to clustering the markers,
  as i search in GOOGLE, i found that there is a library call CLUSTERKARF, it works,but i got some problem on it,<br>
  I dont know how to change the markers' icon, infowindow function disabled....</p>
  
  <p>Do anyone of you had working on that library? or maybe another library or method that i can use?</p>
