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?

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

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

Is there any update on this topic?
I am running Rock Pi 4B in Android 10 and want to access the GPIO, I2C, SPI etc…

Any update on this? I am considering changing from Odroid to this board due to the official Android 12 support, but I don’t know why this hasn’t been handled out of the box from the beginning.
On the Odroid, google.android.things are available for use, enabled by some make files before building aosp.
