Does anyone know if it’s possible to obfuscate Android AOSP or LineageOS Android 13 system app java code or resources for apps like SystemUI, Settings, TvSettings, framework-res.apk if building from source code?

Proguard seems mostly for Gradle apps, not sure if it can be added correctly for apps with Android.bp files. If so how to add it for the above system apps? And will the built firmware still be bootable?

AndResGuard seems to be only for Gradle or 3rd party apps.

There seems to be no way to obfuscate resources in the system apps’ res folder.
