Dictionary blocks in MIT App Inventor | Customer Record App | Storing records in MIT App Inventor
61Hello friends,
In this tutorial, I am teaching you about the dictionary block in MIT App Inventor. I am constructing a customer record app using dictionaries. I will show how to add a dictionary, load it from the database and show its contents to the user. The next class will cover searching records by customer's name and updating and deleting a single customer record.
