荣士ID-01H低频USB免驱动RFID读卡器支持Windows、安卓(Android)、Linux系统，为方便ID-01H读卡器能快速的接入安卓(Android)系统，我们提供了各种安卓版本的So库及示例源码，安卓工程师可直接拷贝以下代码使用到项目中。
按以下4部操作，可快速将So库加载到您的Android工程项目内：
1、将我们提供的开发包里的文件夹libs及OURIDR_V1.aar，一起复制你的项目APP-->libs目录下;
2、修改APP-->src下的build.gradle文件，在buildTypes{}的后面，加入
sourceSets {
main {
jniLibs.srcDirs = ['libs']
}
}
同时在dependencies {}中加入
implementation fileTree(include: ['*.jar','*.aar'], dir: 'libs')
3、加入NDK工具包。
4、java的源文件中加入import com.reader.ouridr;,就可以调用我们在AAR包里的函数了。
