title: Xamarin no longer debugging my app
body: <p>I've been working on a Xamarin project for a few days and have been testing it fine, but today it has suddenly stopped allowing me to debug the app, either via Live Player, or by connecting my smart phone via USB. </p>
  
  <p>The only error I am getting, as far as I can see, is </p>
  
  <blockquote>
    <p>Failed to debug your app</p>
  </blockquote>
  
  <p>I've not got a way of testing it on iOS devices, but the built-in Windows Phone emulator runs the app fine, albeit with an error in my code popping up now and then.</p>
  
  <p>What could be causing the Android version to stop debugging, or how do I at least fix it?</p>
