第二代USB免驱动IC读写器IC-02支持Windows、安卓(Android)、Linux系统,为方便IC-02读写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OURMIFARE_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.ourmifare;,就可以调用我们在AAR包里的函数了。
