Hi

I tried to use dexlib2 to open a dex file (classes.dex) that I unzipped and extracted from framework.jar but I encountered an error

I checked with the file command and confirm that classes.dex is a dex file.

file classes.dex
classes.dex: Android dex file, version 039

I am running the application on Android emulator OS version 14.

The code snippet is taken from https://stackoverflow.com/questions/11343388/is-there-a-way-to-get-a-list-of-all-classes-from-a-dex-file

val dexFile = DexFileFactory.loadDexFile(File("/storage/emulated/0/Android/data/<package.name.redacted>/files/classes.dex"), 29 /*api level*/)
