Clean up simple Android application

Simple Bookshelf App The app is already created I just need some additional functionality added to get it working right and dont have time for it. I just need some simple code for add/search/delete and update done (I think I have done this in the MyDBHandler file, but need to get the buttons working). I may also need to get the main_activity screen with the lists working properly. I am also having problems coding the HOME button to go back to the main activity and the settings option to not display on the main activity screen. The attached file includes the following: -Main Activity screen and associated graphics -Add/Edit Activity Screen with buttons and associated graphics -Database table is attached - Queries are in the MyDBHandler class) Java classes: [login to view URL] -Book Adapter -Books -MainActivity -MyDBHandler
