 #  **ManifestEditor**
+
+Fork from [WindySha/ManifestEditor](https://github.com/WindySha/ManifestEditor) with additional feature to remove previously defined permissions in android Manifest file.
+
+---
+
 This is a tool used to modify Android Manifest binary file.  
 此工具用于修改AndroidManifest二进制文件。比如，更改Manifest文件中的app包名，版本号，更改或新增app入口Application的类名，更改或新增debuggable的属性，增加usesPermission标签，增加meta-data标签等。
 同时，为了更方便使用，提供了直接修改Apk包中的Manifest文件，并对修改后的Apk进行签名的功能。
