+# AndroidApexTools
+
+一个帮助解包android的apex包，并支持重新打包成apex的工具
+
+> 项目地址：https://github.com/wcedla/AndroidApexTools
+
+## 功能说明
+
+> <font style="color:red">当前仅支持linux和wsl子系统，测试环境为win10的wsl2的ubuntu 22.04</font>
+
+### 1. 解包
+
+```shell
+cd 当前脚本存放位置
+sudo python3 ./deapexer.py extract ./foo.apex
+```
+
+解包后会在当前脚本路径生成manifest和payload两个文件夹，manifest文件夹里面的内容一般不需要修改，payload就是原apex里面img解包后的文件，可以修改
+
+### 2. 打包
+
+```shell
+cd 当前脚本存放位置
+sudo python3 ./apexer.py --api 33 ./bar.apex
+```
+
+确保当前路径存在manifest和payload文件夹，api参数表示这个apex的android api版本，是必填项
+
+
+> 注意：重新打包后的apex签名和系统签名不一致，需要核心破解

+- # AndroidApexTools
+
+  A tool to help unpack and repack Android apex packages
+
+  > Project address: https://github.com/wcedla/AndroidApexTools
+
+  ## **Features**
+
+  > Currently only supports Linux and WSL subsystem, tested on Ubuntu 22.04 in WSL2 on Win10
+
+  ### **1. Unpack**
+
+  ```shell
+  cd path/to/script
+  sudo python3 ./deapexer.py extract ./foo.apex
+  ```
+
+  After unpacking, manifest and payload folders will be generated under the script path. The manifest folder contains metadata that usually doesn't need modification. The payload folder contains the extracted img files from the original apex, which can be modified.
+
+  ### **2. Repack**
+
+  ```shell
+  cd path/to/script
+  sudo python3 ./apexer.py --api 33 ./bar.apex
+  ```
+
+  Make sure there are manifest and payload folders under the current path. The api parameter specifies the Android api version for this apex and is required.
+
+  > Note: The repacked apex will have a different signature from the system signature and needs core patch to work.
