Check signing system apk.

Optionally:

You need to create a keystore file by using keytool-importkeypair which you can find here.

Go into the: build/target/product/security/ directory in your platform source tree (source codes related to your Android version and vendor).

You will find platform.pk8 and platform.x509.pem files.

Create keystore file by using this example command:

keytool-importkeypair -k ~/.android/debug.keystore -p android -pk8 platform.pk8 -cert platform.x509.pem -alias platform

You can use this keystore file to sign your apk which will have system permissions afterwards.
