Help with Amlogic AOSP Android 9 customization.

I have Android 9 Amlogic sources for S905X (ampere) TV-BOX. I am working to adapt to our needs. I would need to answer a lot of questions like "how to do", "where best to do" (into which .mk). Alternatively, which tool to use. So far, I only edit .mk manually and then compile, I do not use any IDE. So I want to pay for advice and instructions for me, for explanations.

So I'm looking for someone who knows the structure of the AOSP project, preferably the structure of the AOSP from Amlogic and is experienced in making changes.

I've already made a lot of changes and they work on the physical box.

Beceriler: Android, Linux, XML, Java
