title: Android App more Efficient to Go to DB or Keep Collection in Memory
body: <p>I build my first android app. I have a collection of lists that I display. I'm wondering with a phones small memory size, is it a better design approach to go the database for my list every time or keep it in memory?</p>
  
  <p>I do need to frequently re-order lists, so by just grabbing them out of the database in a sorted order it is pretty fast.</p>
