 ### What is Xposed
 
-> Xposed Framework (Xposed Framework) is a set of open source framework services that run in Android high-privilege mode. It can affect program operation (modify the system) without modifying the APK file. Based on it, many Powerful modules that operate simultaneously without conflicting functions.

As mobile devices in today's era are more and more difficult to obtain Root permissions or even flash, and when they are not just needed, some Root-free frameworks are also produced, such as **LSPatch**、**TaiChi**.
 
 These Hook Frameworks at the ART level can also complete the Hook process with the same principle as Xposed without using the Xposed API. The operating principle of Root-free is to modify the APK and inject the Hook process into the **Host**, and control it through external modules.
 
 Another product is to use the existing functions of the Android operating environment to virtualize an environment that is completely the same as the current device system, and run App in it. This is the virtual App technology **VirtualApp**, which was later derived as **VirtualXposed** .

 ### Xposed 是什么
 
-> Xposed 框架(Xposed Framework)是一套开源的、在 Android 高权限模式下运行的框架服务，可以在不修改 APK 文件的情况下影响程序运行（修改系统）的框架服务，基于它可以制作出许多功能强大的模块，且在功能不冲突的情况下同时运作。

+通过 Xposed 的运行原理，从而衍生了很多同类型框架，随着当今时代的移动设备获取 Root 权限甚至刷机越来越困难且不是刚需的时候，一些免 Root 框架也随之产生，例如 **LSPatch**、**太极**。
 
 这些在 ART 层面上的 Hook Framework 同样也可不借助 Xposed API 完成其和 Xposed 原理一样的 Hook 流程，免 Root 的运行原理为修改 APK 并将 Hook 进程注入宿主，通过外部模块对其进行控制。
 
 另外一种产品就是利用 Android 运行环境现有的功能虚拟出一个完全与当前设备系统一样的环境，并在其中运行 APP，这个就是虚拟 APP 技术 **VirtualApp**，后来衍生为 **VirtualXposed**。
