GPIO with Android

Hi All!
Is there a possibility to control GPIO on Rock PI 4 with an Android java application? I’ve seen there are some old versions with GPIO drivers, but is there Android 7 or above image with tested GPIO capability?

Anyone knows something on the subj?

You can control gpio by reading and writing ‘/sys/class/gpio’ files

Great!, can you give a detailed example of how to control each of the 40 pins? and how to set up the i2c, Spi, and serial outputs?

Kind regards

We have plans to port libmraa to android, just wait for the good news

I found some GPIO libraries while browsing the Armbian forums, maybe they can help:
