how PRODUCT_COPY_FILES works

[nguyenvuthiennga]

Hi all,

I try to push a file into Android image. I have a look at some make
files (.mk) (e.g. frameworks/base/data/sounds/OriginalAudio.mk, vendor/
htc/common-open/akmd/Android.mk) and I see they use PRODUCT_COPY_FILES
variable specify which file they want to push in Android image. I try
to imitate and put in vendor/aosp/products/aosp_core.mk. However it
doesn't work.

Did anyone try this before?

I saw my file in out/target/product/sapphire-open/installed-files.txt
but when I boot Android, I didn't see the file. The folder is empty.

Can anyone help me out?

It turns out that I can copy file to /system/... but can not copy to /
data/...
If I put my file to /system/... then I can not write on the file
later.

When the device has booted, /system is mounted read-only. You cannot
expect to ever be able to write to anything on that partition during
runtime.

Thanks for your reply.

Then, how can I copy files to /data/...?
To be more clear, I don't want to copy to application's area since my
file will be used by the system services. I wonder if I can copy files
to /data/system?

Another way is to create directory /data/my_directory/ and copy my
file to it. I can create the directory by modifying init.rc. However,
I can not use PRODUCT_COPY_FILES to there.

Generally you don't want to put your built output on the data partition, because if the user does a factory reset of their device whatever you put there will be lost forever.
