title: Checking internet connection in every activity?
body: <p>I'm doing this a little late in the process. I have a quite a few screens/activites which all require a connection to the internet, doesn't matter if its wifi or network to work. I can detect the connection fine but do I need to perform this check on every single activity or is there a global way to do this for my application? </p>
  
  <p>Just thought I'd ask before adding a lot of code. </p>
