MQTT Broker for Android Mobile

MQTT Broker      MQTT is a machine-to-machine (M2M)/"Internet of Things" connectivity protocol. It was designed as an extremely lightweight publish/subscribe messaging transport. It is useful for connections with remote locations where a small code footprint is required and/or network bandwidth is at a premium. MQTT Broker for Android Mobile     After the long search I could not find any working android application for running MQTT broker in my mobile, so I decided to make it myself. In this post I am going to show you how the MQTT broker can be written for Android. Moquette for Android     Finally I found the Moquette based  GitHub  fork for the android application. I decided to create simple (very simple... Even there is no UI  ðŸ˜¼ ) application on top of Moquette using the above GitHub project. Thanks to  andsel  (Contributor of this GitHub) Steps  Download the Project from GitHub Create the new A...
