JNI在Android系统下串口控制的应用

Android是基于Linux的操作系统,应用程序是由Java语言编写并运行在虚拟机里的,这就造成了Android应用程序很难操作订制的硬件问题.利用Java的JNI机制,使用Android NDK编译环境,使应用程序可以透过Android系统的应用框架层,直接在Linux的文件系统对设备进行操作,解决了上述问题.

Application of serial port control under Android with JNI

Android is based on Linux operation system. Android applications are written in Java and run in Android virtual machines. As a result, it is difficult to access those hardwares that there＇ s no method to access in Java libraries. This article describes the method to resolve the problem above, which is based on the JNI mechanism in Java and associated with the Android NDK compiling environment. The method can make Android applications access devices on the Linux file system directly without being concerned with the Android application framework.
