Android 混淆与反编译的简单记录

-dontusemixedcaseclassnames          #混淆时不使用大小写混合类名
-dontskipnonpubliclibraryclasses     #不跳过library中的非public的类
-verbose                                #打印混淆的详细信息
-dontoptimize                         #不进行优化，建议使用此选项，
-dontpreverify                        #不进行预校验,Android不需要,可加快混淆速度。
-ignorewarnings                      #忽略警告
-optimizationpasses 5               #指定代码的压缩级别
# 保护代码中的Annotation不被混淆
# 这在JSON实体映射时非常重要，比如fastJson
-keepattributes *Annotation*
#把混淆类中的方法名也混淆了
-useuniqueclassmembernames
#将文件来源重命名为“SourceFile”字符串
-renamesourcefileattribute SourceFile
# 避免混淆泛型
# 这在JSON实体映射时非常重要，比如fastJson
-keepattributes Signature
#-repackageclasses'a'
-flattenpackagehierarchy
# keep住源文件以及行号
-keepattributes SourceFile,LineNumberTable
#------------------  android基本项  ----------------

# 保留了继承自Activity、Application这些类的子类

混淆简单记录，虽然没用到 哈哈哈

反编译

1.下载dex2jar和gui。

dex2jar 这个工具用于将dex文件转换成jar文件

jd-gui 这个工具用于将jar文件转换成java代码

2.将apk解压，将classes.dex复制进dex2jar。

3.cmd进入dex2jar目录下，使用d2j-dex2jar classes.dex，生成jar包。

4.jar包在jd-gui中可以查看目录。
