get_fields() does not work

[GoogleCodeExporter]

Thanks for taking care of my previous issue so quickly. Unfortunately the next 
two steps I tried also produce unexpected errors:

What steps will reproduce the problem?
Run
a = androguard.AndroguardS("attached jar file")

for i in a.get_fields() :
    print i.get_access(), i.get_name(), i.get_descriptor()

What is the expected output? What do you see instead?

raceback (most recent call last):
  File "./bla.py", line 19, in <module>
    for i in a.get_fields() :
  File "/home/spjsschl/androguard/androguard.py", line 474, in __getattr__
    return getattr(self.__a, value)
AttributeError: 'NoneType' object has no attribute 'get_fields'

What version of the product are you using? On what operating system?
Current mercury androguard on ubuntu oneiric

The second issue is probably related. Same applet, same code, except I am 
calling a.get_methods()

Sorry, seems my email from last week got lost. Thanks for working  on this.

I have tried the new version and both problems persist, there is no visible 
effect for the changes on my system.

Your program works even though it has shorter output compared yo your example 
run:

ACC_PRIVATE json/XML j Ljava/util/HashSet;
ACC_PRIVATE ACC_STATIC json/XML i [S
ACC_PUBLIC ACC_STATIC json/XML e Ljava/lang/String;
ACC_FINAL json/XML database Ljson/Parser;

The program that I sent to you initially (and that I used for my testing) still 
does not work:
#!/usr/bin/env python

import sys

PATH_INSTALL = "/home/spjsschl/androguard/"
sys.path.append(PATH_INSTALL)
sys.path.append(PATH_INSTALL + "/core")
sys.path.append(PATH_INSTALL + "/core/bytecodes")
sys.path.append(PATH_INSTALL + "/core/analysis")

import androguard

a = androguard.AndroguardS(sys.argv[1])

# SHOW CLASS (verbose)
#a.show()

# SHOW FIELDS
for i in a.get_fields() :
    print i.get_access(), i.get_name(), i.get_descriptor()

## SHOW METHODS
#for i in a.get_methods() :
#   print i.get_access(), i.get_name(), i.get_descriptor()

output:
Traceback (most recent call last):
  File "./bla.py", line 19, in <module>
    for i in a.get_fields() :
  File "/home/spjsschl/androguard/androguard.py", line 474, in __getattr__
    return getattr(self.__a, value)
AttributeError: 'NoneType' object has no attribute 'get_fields'

Yes I know, could you try with mine ?

I ran your code, see the output in my previous mail.

It is somehow shorter than your example output.

Could you try by changing AndroguardS with JAR + JavaVMFormat ?
