[Q] Building Android 4.4.x custom upgrade
I'm new to building Android ROM. So please correct me if anything doesn't make sense
I have a device that's currently running Android 4.2.2 (Amlogic 8726-mx). I have all necessary source code including uboot, kernel, 4.2.2 source.
I have two questions
- Can I use the existing kernel, uboot source code and merge with the Android 4.4.x source code from google?
- If yes, is it just simply replacing the "system" folder and then run make command to build? If not, can anyone point me to the right direction?
Thank you all in advanced
