Include prebuild apk with libs?

VIM2 Android

Hi,

I try to include presbuild app witch contain lib in apk.

After building, the apk is copied fine in system/priv-app/myApp but the libs are not extracted from apk.

First, I try to manually copy lib in Kvim2.mk.

PRODUCT_COPY_FILES +=
vendor/myApp/lib/arm/myLib.so:system/priv-app/myApp/lib/arm/myLib.so

The lib is copied into /system/priv-app/myApp/lib/arm/myLib.so. Now I need to have executable permission on myLib.so but system is read-only. I can manually mount system as writable and set permission but how to automatically do that ?

I try to edit init.rc but it can’t set permission.

There is another method to install lib ? Or how i can automatically set permission ?
