I'm working on an independent app and am following some basic tutorials. From what I can tell, the code is virtually the same as the guides I'm following, but when I try to run the application on the emulator, I'm getting the "unfortunately has stopped working" message. I'm having some difficulty interpreting the errors in the logcat because a lot of the directed lines of code are the default code created when I started the new files. Any help would be appreciiated, thanks
