Libusb在Android下的应用eclipse工程
Libusb是一个开源库，主要用来实现通用的USB设备通信接口，它允许用户空间程序直接与USB设备进行交互，而无需依赖操作系统内核模块。在Windows、Linux、macOS等多种操作系统上都有广泛的应用。而在Android环境下，由于其原生不支持libusb，我们需要通过一些额外的手段来使用这个库。
`Libusb在Android下的应用eclipse工程`意味着我们要在一个Eclipse环境中搭建一个Android项目，该项目的目标是实现libusb的功能。Eclipse是早期常用的Android开发环境，虽然现在Google已经推荐使用Android Studio，但在某些情况下，开发者可能仍然选择Eclipse。
要将Libusb集成到Android项目中，我们需要使用NDK（Native Development Kit），这是Android系统提供的用于开发C/C++原生代码的工具集。通过编写JNI（Java Native Interface）代码，我们可以创建一个桥梁，使得Java层能够调用C/C++编写的libusb函数。
具体步骤如下：
1. **设置环境**：确保你已经安装了Eclipse、Android SDK、NDK，并且配置了对应的环境变量，使得Eclipse可以识别和使用它们。
2. **创建Android工程**：在Eclipse中新建一个Android项目，选择合适的API级别，因为libusb可能需要特定版本的支持。
3. **添加libusb源码**：将libusb的源码文件下载到项目中，或者将其链接为外部库。你需要根据Android的架构（armeabi、armeabi-v7a、x86等）编译适合的libusb版本。
4. **编写JNI代码**：在项目的jni目录下创建头文件（.h）和源文件（.c或.cpp）。在头文件中声明Java层调用的C函数，这些函数会调用libusb的API。源文件则实现这些函数。
5. **构建JNI库**：使用NDK的ndk-build工具编译JNI代码，生成.so动态链接库文件。这些库文件将被包含在APK中，供Android设备使用。
6. **Java层调用**：在Android应用的Java代码中，通过`System.loadLibrary("libname")`加载库，然后使用`native`关键字声明的方法来调用JNI接口。
7. **权限申请**：由于涉及到USB设备访问，需要在AndroidManifest.xml中添加USB相关的权限，例如`
