title: Local storage of REST/JSON web service results in Android SQLite DB
body: <p>I'm developing my first android application which is basically a task manager in a professional context.
  My data comes from a central server and the user can only modify the progression rate and the number of hours he worked on a particular task.
  He can also search by task name/date/project/client...
  I'm wondering if i need to store the tasks that i get from the server in a local database ? 
  Would the application be too slow if i get the tasks at each session,put them all in a list then preform my operations on that list ? </p>
  
  <p>Thanks in advance.</p>
