title: Decompile XAPK file
body: <p>I have worked pretty a lot analyzing Android projects with different reverse engineering tools, generally for secure purposes, to see what can be seen by a hacker when he/she gets my app. I've met a problem that I couldn't find any of decompilers capable to decompile files of "XAPK" format (not simple APK).
  I know, asking for a way to find a tool is not kind of questions good for stack overflow, but I am pretty sure there are many people with the same problem and I find it highly relevant.
  I tried <a href="http://ibotpeaches.github.io/Apktool/" rel="noreferrer">apk-tool</a>, decompilers provided with <a href="https://code.google.com/archive/p/androguard/" rel="noreferrer">androguard</a> tool, online-decompilers, none of them are capable of working with XAPKs.</p>
