In order to have a multiplatform application, i have a question a little special:

It's how to convert the file "APK" to "JAR".

Thanks for all

Answer 1

dex2jar converts .apk to .jar, but you still have .class files in there. Those that do not link to the Android framework (which are probably only a few utility classes) should be reusable for another platform.

Using jd-gui you can even look at the java code (most of the time at least)

And if you want to extract the resources (you probably need to images too if you want to "convert" it to a different platform) apktool

But there is absolutely no way to take an .apk and run it through a converter and have a Windows program.
