GrapheneOS Oops, I saw 16-qpr2 and didn't realize that was a fork, sorry for misleading you. By the way, are you still interested in implementing the QR code MDM provisioning feature, and what you mean by "major changes"? We can adapt the code to 16-qpr2 (I believe no or minor changes required) and squash the commits as per the review of @de0u, but adding the source code of ZXing and updating versions of other libraries needs discussion with your dev team as these changes are related to shared code and may potentially affect other parts of GrapheneOS. If a member of your dev team will contact us to clarify your requirements, we could proceed further.
