Android Question MQTT function exactly like FCM

[Global Robot Empire]

Fascinated by MQTT.

Thank you @Erel for your Chat example.

Wanna make MQTT function exactly like FCM.

Trying a way – gimme two weeks.

I do slowly.

Posting Source Code – only if it works.

Push notifications feature is an OS feature.

For MQTT to work in a similar way, you will need to keep your app running all the time. It doesn't really work, at least not on all devices.
Background location tracking

Just gonna tinker 'n try various methods.

If need any help, you're there @Erel
