title: App crashes when switching from wifi to mobile network
body: <p>I have an android app that tried to connect to a website in an AsyncTask and perform some tasks. My application always seems to crash when there is a change in the network connection i.e The app is connected to a wifi network initially, but loses connection and switches to mobile network. When this happens my Android Application crashes. My code is surrounded within a try catch block, so I'm not sure why the application would crash ? How do I fix my problem ?</p>
  
  <p>Thanks!</p>
