Can't extract vdex

[4lMaghraby]

I want to extract vdex of the settings app (odex+vdex) in order to completely decompile it here is the link with boot.vdex and the settings app folder https://drive.google.com/open?id=1ycfsnYk9KsuNGyEYXQzKdYzFqSERQXBz thanks in advance

This vdex file has no dex data, open settings.apk and you will find original dex file there.

As @Furniel mentioned the Vdex container does not contain any Dex data (used as a simple reference file from ART).

In this case you can extract the Dex file from the APK (simply unzip it). Be aware that the one you provide in the link is corrupted (most likely an error happened when you downloaded from the device). Redownload it from the device and you should be ok.
