Android Example Chat Mqtt Over Internet Free Source Code B4A/B4J

Hi to all
Based on this link https://www.b4x.com/android/forum/threads/b4x-cross-platform-chat-layout-example.112649/#content
I have added MQTT.
It's a simple example that I want to share with you
Have fun improving it, perhaps adding a base64 security on the string etc.
Note: if you change the topic name, remember to split the string

GetIDFromTopic = Topic.SubString(10)'get UserId

otherwise the way of writing on the chat is wrong.
The attached examples are client.
You can install it on multiple devices.Each app has a different id.

I have a Raspberry Pi Zero running as an MQTT broker and going to try this.
Thanks for sharing.

The attached example B4J also works great on raspberry pi 3 with UI interface.
