Simple Android (Kotlin) TCP/IP messaging example

This is a simple Android phone/tablet Kotlin messaging example. The communication is done via 2 Android devices(will do a Kotlin desktop app later on) that support wifi and are in the same network. It uses TCP sockets to send/receive the messages from one to another. This is just a simple pet project to exercise my skills with various technologies.

This is work in progress for now! :)

I would like to try out the following Android APIs:

• Kotlin Coroutines (replace the current AsyncTask)
• Kotlin Flow (listen to messages using Flow instead of the traditional callback)
• Jetpack's Architecture Components ViewModel + LiveData (moving away from the ugly "do it all" activity)
• Unit testing the thing (see how all the above can be tested to cover our a*s)
