Dave Moss: Persist
For this app I decided to make an app for keeping track of bank accounts. The app allows you to add/delete accounts that you have and add transactions to those accounts or delete them. The app updates the balance of each account based on the type of transactions they add to each account, and the user can also update the balance manually if they forget to add some transactions. I learned a lot about passing data in between activities from this app as I had multiple activities that needed access to the database. I also learned that a list item that has a button added to it apparently will not respond to onListItemSelected events anymore.
