The MQTT Android Service is an MQTT client library written in Kotlin. It has been created to provide reliable open-source implementations of open and standard messaging protocols aimed at new, existing, and emerging applications for Machine-to-Machine (M2M) and Internet of Things (IoT). MQTT reflects the inherent physical and cost constraints of device connectivity. Its objectives include effective levels of decoupling between devices and applications, designed to keep markets open and encourage the rapid growth of scalable Web and Enterprise middleware and applications.

The main advantages
- it doesn't use
android.permission.SCHEDULE_EXACT_ALARMwhich drain the battery - it uses
androidx.work:work-runtime-ktxto receive messages during device sleep
When you use a version 3.x on Android >= O you should use it as foreground service
val client = MqttAndroidClient(context, uri, clientId).apply {
setForegroundService(foregroundNotification, 3)
}
