All new tutorial: Using TinyDB in App Inventor
I have completely rewritten and re-done my original tutorial on using TinyDB in App Inventor.
You can see the all new rewrite at Using TinyDB in App Inventor
TinyDB is a database used to store and retrieve values to semi-permanent storage on your phone or tablet. Unlike variables, which vanish when your app closes or your phone is turned off, values stored in the TinyDB are retained and can be accessed again, much later.
The original post was a popular post here on the blog, but it was brief and left out some details. I started over from scratch and wrote an all new, complete tutorial, with screen shots and blocks code, and downloadable App Inventor source code. Hope this helps!
