There are some error log about fastjson about dex2jar HOT 2 CLOSED

Thanks for reporting! I found the issue and fixed it accordingly.
I will reply here again as soon as the changes are online :)

The issue is in these lines:

String elementTypeA = a.substring(as);
String elementTypeB = a.substring(bs);

As one can see, elementTypeB uses the String a, which is of course not what we want.
So, I've just changed it to b and your APK is decompiling perfectly fine for me now :)

from dex2jar.

The new build is being deployed right now. v25 should be available via releases
