Android Development for Beginners 17

App Inventor TinyWebDB ExampleIn this part of my App Inventor tutorial, I will provide an App Inventor TinyWebDB Example. This one should be fun. We’ll be making a chat application that I call IncognitoEx. It will allow you to chat with anyone who also has the app. Here is the APK if you want to try it out.

It allows you to send and receive messages. You can find the messages here You can even make your own TinyWebDB web service by following the directions here Creating a Custom TinyWebDB Service. All of the blocks can be found after the video below.

      Hi Dileepa,

      Sorry, but I’m confused by the error. I ran my app and it worked. Did you make your own TinyWebDB service?
