User Stories

The following required functionality is completed:

• [x] User can tap a todo item in the list and bring up an edit screen for the todo item and then have any changes to the text reflected in the todo list.

• [ ] Add support for selecting the priority of each todo item (and display in listview item)

Notes

Challenges encountered while building the app:

• Had some issues running the 'app' with other APIs besides API 23

  Update: The issue was generated due to the readItems() statement in onCreate method when the app initially tried to read the list of items in a text file that didn't exist. The issue is now fixed after the implementation of SQLite.

• Figuring out how to use Intent and Extras took quite some time

• Picking the right color combinations that can go well with the background image was hard
