In that case you need to copy over the libraries, see https://github.com/koreader/android-...ment-520148127

If you place the app in /system/app libraries go in /system/lib or /vendor/lib
if you place the app in /system/priv-app/koreader libraries go in system/priv-app/koreader/lib/{arm,x86}

(I have no idea why Android doesn't just do that, but whatever…)
