title: Android gestures not working
body: <p>This is my main Java file, I'll also include my XML file, the problem is simply that the app does nothing, I need to get it to swipe to change page <code>newPage()</code> but nothing works. I've got a button in it that is invisible but this method isn't smooth enough for what I'm trying to do with the app.     </p>
