title: Android app which works in online and offline mode?
body: <p>I'm new to Android and and made an application which fetched and post data to server and works fine in online mode. But I want to make it works in offline mode also, when there is no internet connection or network failure. It should also make changes (updates) to the server database when net is available. I have done lots of R &amp; D but didn't get the useful info.</p>
  
  <p>Please someone guide me with some useful steps, sample code (if possible) or any link to make app in offline mode.</p>
