title: Android: How to query a list of bucket name
body: <p>I want to retrieve only the name of the bucket (Albums). E.g. Camera, Download etc but not a list of Camera, Download etc from all the the photos so how do I retrieve one row each for each bucket name?</p>
  
  <p>What I mean like in Gallery Application, you have albums first e.g. Camera. When you clicked on it, it show all the photos of the camera.</p>
  
  <p>I can query the photos in a Camera Roll with the Where clause of the query. But what if I wanted only the name of each of the albums' name and not the photos, is it possible to query that? If I query all the photos and take only one row per set of photos, then it will be time consuming.</p>
  
  <p>Please Help</p>
