title: managedQuery() vs context.getContentResolver.query() vs android.provider.something.query()
body: <p>Pretty simple.
  What is the difference among those three?</p>
  
  <p>I want to list every Image in a device.
  Should I use <code>managedQuery()</code>, <code>android.provider.MediaStore.Images.Media.query()</code> or <code>context.getContentResolver.query()</code></p>
