I need a small custom Android app developed which will connect to my business's Paypal account via the Paypal API, fetch all my sales data, sort it, and display it neatly as both a table and a graph.
This app requires a basic user interface with neat-looking buttons, a couple of tabs, and a couple of drop-down fields, but nothing fancy. This app will only be used by me and nobody else, so we don't need to worry about compatibility issues, etc. My device is a Samsung Galaxy S3 running Android 4. I can provide graphics for the UI if necessary, or you can use a basic UI theme of your own.

Here are the key features I need:
1) The app should store my credentials so it can easily fetch sales data via the Paypal API without bugging me for a password every time.
2) I need drop-down fields for several different ways the sales data can be filtered:...
