Should the AppDatabase be a singleton?

@lgleason Can you please help with this when you get a chance? Thank you - much appreciated! :]

Apologies Its actually a mistake of mine. I see it is a singleton through ListMasterApplication. Thanks anyway!

That is correct, it should be a singleton. The reason for that is because spinning up the elements behind Room are expensive. While you could choose not to, you would expend a lot of CPU and memory resources un necessarily doing so which is why Google recommends following a singleton pattern.
