Notes
Figuring out how to see content in the File Explorer in Android Device Monitor required some research. Apparently when using a virtual device with API 25 it doesn't show anything. I had to change the device to use API 23 for it to work properly. I had a lot of trouble modifying table columns after I started using FlowDB and decided to update my TodoItem model. I tried using migrations but couldn't get it to work. Eventually decided it was faster to simply uninstall the app and start with fresh database every time I had to change the model, though I realize this would not work for an app that's live in production.
