I added the following messages for registering a new account. It pulls
the messages using the register PHP.

Error message 1 - None (Success)
Error messsage 2 - Already an account
Error messsage 3 - Not an email address
Error messsage 4 - Password too short (4) or too long(24)

Error messsage 5 - First and/or Last name are blank

Fixed hitting back on the login screen. Fixed the logout button.

I put a broadcastrceiver in every activity. The logout button and the
back button on the Login screen broadcast a 'CLOSE_ALL' message to all
off the activities forcing them to finish().
