A sample app demonstrating a quick workaround to using PahoMQTT in Android Oreo+ using foreground notification
PahoMQTTClass is controlled by the singleton
ConnectionHolder, which manages the mqttCallback.
- Due to a restriction on the background services in Android Oreo onwards, the MQTT service is wrapped in the
NotificationServicewhich is a foreground service with a persistent notification.
- The notification can be modified, and the sample start button listener can be used to determine how to start the service.
