    Exclamation Fragments

    I am trying to develop an app that uses a stand-alone activity as an entry point(log in screen). Fragments only come in when the user has logged in. Problem is when I hit the log in button, the emulator says the app has stopped working. I've declared all my activities in the android manifest file so I cant seem to understand what the problem is and I am stuck.
