Custom devices in mobile app for Android

How I can add sensors from Custom device (added from Cayenne MQTT API (C library)) to my android app Cayenne?
Section “Devices” just empty.
When I’d added “raspberry pi” it was there, but I’m really need my Custom device here, not arduino and not RPi

Hi
For Cyenne MQTT API is not yet support the Android App.
But it is in the plan.
