Read JSON in MIT App Inventor | How to Decode JSON File | MIT App Inventor File #json #appinventor
48Hello friends,
In this tutorial, I am teaching you about JSON (Javascript Object Notation) and how a JSON file is decoded in MIT App Inventor using the Dictionary Block. First, I am teaching how to read a JSON text file into the system. After reading the JSON file, it is decoded and stored in a global variable and I am also teaching how we can search through this data to find some particular information.
