How to build Android 9 for the Rock64
#1
Follow the steps on the repository here:

https://github.com/a9rock64/manifests

Code:
repo init --depth=1 -u https://github.com/a9rock64/manifests.git -m a9rock64_us.xml -b default

Code:
repo sync  -f -c --no-clone-bundle --no-tags -j$(nproc --all)

Code:
. build/envsetup.sh
./build_box.sh

I made a docker image with the required build environment dependencies:

When I build using the method outlined above, I get the following error:

Fixed by installing pycrypto:

Good to have the instructions here. Thanks.
Are there any special tricks to include opengapps into the build?

Haven't gotten that far <3

Sorry my friend. The binary image of android9 for rock64 does not have Gapps at all. I thought i should do something special to add them to the repo. But they seem to be cloned along with other staff.
What is expected download size?

Of the repo entire 9 repo? Probably around 100 GB.

Not sure how much just the gapps repo is.

Ohoh. Got bus error after 8 hours of compile

The build_box.sh seems to start from the beginning every time despite the compilation status. Is it possible to continue process somehow?

Thank you, dazza
Flashed it without problems, but i see some issues with screen on this build. It continuously blinks changing resolution randomly while surfing through the home screen and launching apps. The box is connected to quite old Philips fullhd TV. I do not remember this behavior on stock binary. And there is not possible to change display resolution from Auto. Not good but i can live with that.
Another annoying feature is randomly changing MAC address of eth0 with every new image - it costs 5euro every time to register SIPTV app to new MAC addr ))
I seem to find how to fix that with uboot environment CONFIG_ETHADDR written directly to u-boot/configs/rk3328_defconfig and uboot recompilation. Will check this weekend if it works. Not sure if there is any other method.
Finally i rooted the image with Magisk using the method described in RKDocs/android/Rockchip_Magisk_installation_guidelines.pdf of the repository.
