Hi everyone! I'm researching about build custom ROM with AOSP. Now I get problem about how to include Superuser in the ROM. I want after flash ROM user can be already using. I tried copy su binary and superuser apk from zip file and put into system/xbin/su and system/app folder. After flash ROM superuser appear but it notify Su binary need update... Second way I tried work with the guide from Cyanogenmod but same problem. How can I add superuser into custom ROM by other solution?
