Android 7.1.2. libmraa gpio

Hello,

We have installed Android 7.1.2 on Rockpi 4. We have the requirement for using official 7" raspberry pi screen with DSI.

For this Android version, is any option to use libmraa? We have been testing it but native .so is not found. I supose is not included with Android 7.1.2. Is there any Android imagen can work with GPIO through libmraa and DSI touchscreen port?

Thanks very much
