I need a small Android app with mqtt library. It will connect to a mqtt server and transfer messages. This will be a demo app in java. Once you are successful in delivering this we will expand the project to a full featured iot app.
For this project the app needs to connect to a mqtt server, subscribe and exchange messages. I will share the mqtt server details. The app will have one screen which will show messages received and a text box for sending messages. Please include if you have worked with mqtt before
