Troubles installing programmatically an app with INSTALL_PACKAGES permission from /system/app

Answer 1

Refer to signatureOrSystem permissions on custom ROM

Basically,

1. add the required
2. push apk to /system/priv-app

Done (well, at least works for me).

You do not need to add android:protectionLevel="signatureOrSystem" or android:sharedUserId="android.uid.system". You could sign with any certification.
