You don’t need root to pull the apk files from /data/app
. Sure, you might not have permissions to list the contents of that directory, but you can find the file locations of APKs with:
adb shell pm list packages -f
Then you can use adb pull
:
adb pull <APK path from previous command>
and then aapt
to get the information you want:
aapt dump badging <pulledfile.apk>
