Todo List Android App -- Clean up code -- Espresso and Unit Tests Trying to improve this code and separate the business logic as much as possible. I am feeling kind of lost lol. Any advice on how to test this app and clean up the code would be very appreciated. I don't want to post all of the code on here so I will link my repository on GitHub. Really need this explained simply. Thank you for your time!! link -> https://github.com/sammorton11/NotesApp class AddEditNoteActivity :...
