I've tried the following libraries :
react-native-native-mqtt
react-native-mqtt
react_native_mqtt
sp-react-native-mqtt
Most of them gave me the same Error :
null is not an object (evaluating 'Mqtt.createClient')

.... its pretty long and probably says nothing of value.
The ones that didn't give me this error; gave me errors about sockets and buffers, almost as if it was trying to run it over web sockets.
What am I doing wrong here?
Is it even possible to get MQTT messages on android react-native?
Is Expo the problem?
I had the same problem. An expo Project and fear of ejecting from Expo.
My actual solution starts from here!
After a lot of research, I found this module. Eclipse Paho MQTT Client for JS
npm i paho-mqtt
