This is a tool to repackage apk file, then the apk can load any xposed modules installed in the device. It is another way to hook an app without root device.

Android App破解工具Xpatch的使用方法

Xpatch概述

Xpatch用来重新签名打包Apk文件,使重打包后的Apk能加载安装在系统里的Xposed插件,从而实现免Root Hook任意App。

Xpatch基本原理

Xpatch的原理是对Apk文件进行二次打包,重新签名,并生成一个新的apk文件。 在Apk二次打包过程中,插入加载Xposed插件的逻辑,这样,新的Apk文件就可以加载任意Xposed插件,从而实现免Root Hook任意App的Java代码。

1.0~1.4版本,Hook框架使用的是Lody的whale
2.0版本开始,Hook框架底层使用的是ganyao114的SandHook
3.0版本开始,默认使用SandHook,同时,兼容切换为whale

Xpatch工具包下载

下载最新的Xpatch Jar包
或者进入Releases页面下载指定版本:releases

Xpatch使用方法

Xpatch项目最终生成物是一个Jar包,此Jar使用起来非常简单,只需要一行命令,一个接入xposed hook功能的apk就生成:

$ java -jar XpatchJar包路径 apk文件路径

For example:
$ java -jar ../xpatch.jar ../Test.apk

这条命令之后,在原apk文件(Test.apk)相同的文件夹中,会生成一个名称为Test-xposed-signed.apk的新apk,这就是重新签名之后的支持xposed插件的apk。

Note: 由于签名与原签名不一致,因此需要先卸载掉系统上已经安装的原apk,才能安装这个Xpatch后的apk

当然,也可以增加-o参数,指定新apk生成的路径:

$ java -jar ../xpatch.jar ../Test.apk -o ../new-Test.apk

更多参数类型可以使用--help查看,或者不输入任何参数运行jar包:

$ java -jar ../xpatch.jar --h(可省略)

这行命令之后得到结果(v1.0-v2.0):

Please choose one apk file you want to process. 
options:
 -f,--force                   force overwrite
 -h,--help                    Print this help message
 -k,--keep                    not delete the jar file that is changed by dex2jar
                               and the apk zip files
 -l,--log                     show all the debug logs
 -o,--output <out-apk-file>   output .apk file, default is $source_apk_dir/[file
                              -name]-xposed-signed.apk

Xposed模块开关控制的两种方法

1. 手动修改sdcard文件控制模块开关

当新apk安装到系统之后,应用启动时,默认会加载所有已安装的Xposed插件(Xposed Module)。

一般情况下,Xposed插件中都会对包名过滤,有些Xposed插件有界面,并且在界面上可以设置开关,所以默认启用所有的Xposed插件的方式,大多数情形下都可行。

但在少数情况可能会出现问题,比如,同一个应用安装有多个Xposed插件(wechat插件就非常多),并且都没有独立的开关界面,同时启用这些插件可能会产生冲突。

为了解决此问题,当应用启动时,会查找系统中所有已安装的Xposed插件,并在文件目录下生成一个文件 mnt/sdcard/xposed_config/modules.list,记录这些Xposed插件App。 比如:

com.blanke.mdwechat#MDWechat
com.example.wx_plug_in3#畅玩微信
liubaoyua.customtext#文本自定义

记录的方式是:插件app包名#插件app名称

需要禁用某个插件,只需要修改此文件,在该插件包名前面增加一个#号即可。

比如,需要禁用畅玩微信文本自定义两个插件,只需要修改该文本文件,增加一个#号即可:

com.blanke.mdwechat#MDWechat
#com.example.wx_plug_in3#畅玩微信
#liubaoyua.customtext#文本自定义

如果需要禁用所有插件,只需在所有的包名前面增加#

注意: 有些App没有获取到sd卡文件读写权限,这会导致无法读取modules.list配置文件,此时会默认启用所有插件。这种情况下,需要手动打开app的文件读写权限。

2. 通过Xposed Tool App控制模块开关

下载并安装Xpatch App(Xposed Tool) 点我下载XposedTool Apk 通过Xposed模块管理页面来控制模块开关。(原理跟方法1一致)

assets目录下的classes.dex是来加载设备上已安装的Xposed插件,其源代码也已经开源:

欢迎star and fork.

局限性

Xpatch是基于apk二次打包实现的,而且使用到了dex2Jar工具,因此,也存在不少的局限性。大概有以下几点:

  1. Hook框架默认使用的是SandHook,此框架存在一些不稳定性,在少数机型上hook可能会崩溃。
  2. 对于校验了文件完整性的app,重打包后可能无法启动;
  3. Xposed Hook框架暂时不支持Dalvik虚拟机。
  4. 暂时不支持Xposed插件中的资源Hook。

功能更新


1. 2019/4/15 updated

增加自动破解签名检验的功能,此功能默认开启,如果需要关闭可以增加-c即可,比如:

$ java -jar ../xpatch.jar ../Test.apk -c

通过help(-h)可以查看到:

options:
-c,--crach disable craching the apk's signature.

2. 2019/4/25 updated

增加将Xposed modules打包到apk中的功能 通过help(-h)可以查看到:

-xm,--xposed-modules the xposed mpdule files to be packaged into the ap k, multi files should be seperated by :(mac) or ;( win)

使用方式为在命令后面增加-xm path即可,比如:

$ java -jar ../xpatch.jar ../source.apk -xm ../module1.apk

假如需要将多个Xposed插件打包进去,在Mac中使用":",在Windows下使用";",隔开多个文件路径即可,比如:

mac
$  java -jar ../xpatch.jar ../source.apk -xm ../module1.apk:../module2.apk  

windows
$  java -jar ../xpatch.jar ../source.apk -xm ../module1.apk;../module2.apk

注意:

  1. 多个Xposed modules使用:(mac)/;(win)分割;
  2. 假如此module既被打包到apk中,又安装在设备上,则只会加载打包到apk中的module,不会加载安装的。 这里是通过包名区分是不是同一个module。

3. 2020/02/09 updated (Version 3.0)

3.0版本增加了不少新功能,同时修复了一些用户反馈的Bug。

新增功能:

  1. 支持android 10;
  2. 支持更改植入的hook框架,默认使用Sandhook(支持android10),可更改为whale(暂不支持android10)(-w);
  3. 默认使用修改Maniest文件方式,植入初始化代码,同时,支持更改为老版本中的修改dex文件的方式植入代码(-dex);
  4. 支持修改apk包名(一般不建议使用,很多应用会校验包名,会导致无法使用)
  5. 支持修改apk的version code;
  6. 支持修改apk的version name;
  7. 支持修改apk的debuggable为true或者false;

Bug修复:

  1. 修复Manifest文件中未定义ApplicationName类,导致无法实现Hook的问题;
  2. 修复破解无so文件的apk时,出现无法找到so的问题;
  3. 修复签名可能会失败的问题;
  4. 修复dex文件数超过65536的问题;

新功能用法

在命令行中输入-h,可以看到3.0版本完整的帮助文档: $ java -jar ../xpatch-3.0.jar -h

options:
 -c,--crach                   disable craching the apk's signature.
 -d,--debuggable <0 or 1>     set 1 to make the app debuggable = true, set 0 to 
                              make the app debuggable = false
 -dex,--dex                   insert code into the dex file, not modify manifest
                               application name attribute
 -f,--force                   force overwrite
 -h,--help                    Print this help message
 -k,--keep                    not delete the jar file that is changed by dex2jar
                               and the apk zip files
 -l,--log                     show all the debug logs
 -o,--output <out-apk-file>   output .apk file, default is $source_apk_dir/[file
                              -name]-xposed-signed.apk
 -pkg,--packageName <new package name>modify the apk package name
 -vc,--versionCode <new-version-code>set the app version code
 -vn,--versionName <new-version-name>set the app version name
 -w,--whale                   Change hook framework to Lody's whale
 -xm,--xposed-modules <xposed module file path>
                              the xposed module files to be packaged into the ap
                              k, multi files should be seperated by :(mac) or ;(
                              win) 
version: 3.0

具体用法:

  1. 修改Apk的debuggable = true:
    $ java -jar ../xpatch-3.0.jar ../Test.apk -d 1 (false改为0)
  2. 使用老版本的破解dex方法破解apk:
    $ java -jar ../xpatch-3.0.jar ../Test.apk -dex
  3. 修改包名,版本号:
    $ java -jar ../xpatch-3.0.jar ../Test.apk -pkg com.test.test -vc 1000 -vn 1.1.1
  4. 更改Hook框架为whale:
    $ java -jar ../xpatch-3.0.jar ../Test.apk -w

4. 2021/01/13 updated (Version 4.0)

Update SandHook to the newest version and SandHook support the Android 11.

Thanks
