title: How to make an Alert Dialog Box in android?
body: <p>I once read a tutorial but since then my phone had been wiped out by XBOX, and so I lost it. I want there to be a button on the MainActivity to open up an AlertDialog Box stating app info such as version number, about current version, what android version this one is for, etc.</p>
