Add prebuilt APKs to Android AOSP system.img

Question

I'm building AOSP from source. What I would like to do is to include a few prebuilt files in the generated system.img as part of the make process. I'm trying to find the actual file that creates the system.img and add a few lines there. Any idea?

Thank you in advance.

Answer 1

A good way of adding custom files to the system.img is to add them under vendor/your_name/product_you_want_to_add_them/proprietary/your_files_go_here and add a custom make file called device-product_name.mk.

After that's done, just define which files are to be copied from the proprietary folder and inside (e.g. vendor/samsung/crespo/device-vendor.mk add to call your device make file).
