apktojava's Issues

Does not work with multidex applications, it picks the first one dex file and shows the java code

Does not work on files with multiple periods.

For example, "android.example.apk" will ALWAYS fail unless it is renamed, regardless of if it actually has a .dex file in it.

Hardcoded dex2jar version

Hi @ajitsing , thanks for this Gem

Issue

I've tried to run it on MacOs and found and received the following error

user@MacBook-Pro-di-User ~ % apkToJava /Users/myuser/Desktop/base.apk
Initializing setup!!
checking for curl... yes
Installing dex2jar..
Warning: dex2jar 2.1 is already installed and up-to-date.
To reinstall 2.1, run:
  brew reinstall dex2jar
Done!
Setup done :)

Cause

Looking at the source code for mac_setup.rb, the DEX_TO_JARconstant is hardcoded to the 2.0 version.

Since the latest version available is 2.1, the error above is thrown.

Possible solutions

At the moment, I've managed to fix the issue by changing the mac_setup.rb file by updating the hardcoded reference from 2.0 to 2.1.

It would be nicer to have the apkToJava to automatically use the latest version of dex2jar

Setup completes without installing the required softwares, when wget is not installed

when you don't have wget installed on your machine and run apkToJava setup it gives following output:

Initializing setup!!
Installing jadx..
sh: wget: command not found
Done!
Setup done :)

Here it did not install jadx because the wget command was not present, but still it shows setup is complete.
