I have learned how to put bootanimation.zip into /system/media/ on the installed system or e.g. into out/target/product/evk_8mm/system/media/ in the android_build directory.
But how can I put it into the android sources, so it is placed into .../system/media during the build process?
Is there e.g. some binaries directory from where bootanimation.zip is copied to .../system/media
like described in the last paragraph of this instructions to the Digi Embedded for Android for the ConnectCore 6 ?
