title: Android IO operations on main thread
body: <p>My question is two fold:</p>
  
  <ol>
  <li><p>Is doing IO operations on main thread in Android advisable or does it have a potential to crash my app.</p></li>
  <li><p>If doing IO operation on main thread not ideal, what other frameworks I can use so that when my app loads it can do some basic IO file reads and can store the values in variables.</p></li>
  </ol>
