通过Android studio逆向apk时输出字符串

使用Android studio 逆向代码时，市场遇到变量是一个数组，其实数组中内容包含字符串，但是Android studio无法识别，可能因为android studio string是默认unicode格式吧，学艺不精，不知道怎么操作才能把字符显示出来。期望有知道的留言告诉我呀。。

就写了个脚本，把数组复制出来然后提取处之后，自己转换一下吧。

复制出来的数组是这样的：

0 = -91 (0xA5)

需要先提取出0x**的数字部分，然后再转换一下：

# -*- coding: utf-8 -*-

"""
import re
pattern = '0x[A-Za-z0-9_]*'
f = open('probuff.txt')
fw = open('writebuff.txt','w')
fc = open('ascii.txt','w')
contents = f.readlines()
for line in contents:
    s1 = re.search(pattern,line)    
    #print(s1.group())
    char = int(s1.group(),16)
    if char>32 and char < 127:
        #fc.write(chr(char))
        pass
        print(chr(char))
        fc.write(chr(char))
    fw.write(s1.group()+',')
    #print(char)
    #print(type(s1.group))

f.close()
fw.close()
fc.close()

上面代码可以取出里面的0x**，如果是可见字符的话还会转换。
