parse WhatsApp get "AssertionError: reserved must be zero"

[deafwolf]

Hi,

When I tried to parse WhatApp.apk, it threw “AssertionError: reserved must be zero.”
I downloaded apk from https://www.whatsapp.com/android

In [1]: from pyaxmlparser import APK

In [2]: apk = APK('WhatsApp.apk')

In [3]: apk.icon_data
---------------------------------------------------------------------------
KeyError                                  Traceback (most recent call last)

   1477 try:

   1479 except KeyError:

KeyError: 'resources.arsc'

During handling of the above exception, another exception occurred:
