title: Content Provider filtering query, filtering Cursor
body: <p>I got following problem, I need to use a Content Provider to read a
  Database of an other App.
  first I want all rows, and after analyzing the data only e.g. the rows
  from _id = 1, 3 and 5.</p>
  
  <p>how can I call a Content provider and select only these rows?</p>
  
  <p>or is it possible to create a subset Cursor form an given Cursor?</p>
  
  <p>Thanks in advance.</p>
