Get Blocks and Everything else Here :

Best Android Book :

In this part of my App Inventor tutorial I will answer a bunch of questions. I’ll cover how to plan an application so that you can cut down on errors and have no problem with the blocks.

I will also show how to make a Android contacts app that store lists of people. You’ll also store that information in a TinyWebDB. We will then be able to update lists of lists on other screens.
