title: Android: Distinct and GroupBy in ContentResolver
body: <p>What would be the correct way to add <code>DISTINCT</code> and/or <code>GROUPBY</code> to <code>ContentResolver</code>-based queries?</p>
  
  <p>Right now I have to create custom URI for each special case.</p>
  
  <p>Is there a better way?</p>
  
  <p>(I still program for 1.5 as lowest common denominator)</p>
