这是一个在android下进行gpio驱动开发的例子，在这个例子中分别从底层驱动代码到测试程序再到android上的JNI层，然后通过java代码调用APP Framework层的接口实现对开发板上led的控制-This is carried out under a gpio android-driven development example, in this case were driven from the bottom to the android code to the test pr

Real210开发板附带的的Android 的实例代码，程序的功能是，驱动电路板的LED。-Real210 development board comes with the Android code examples, the functionality of the program, the drive circuit board LED.

以LED为例说明android应用程序是如何通话JNI调用驱动程序的-LED as an example to illustrate how the android app is calling JNI calls the driver' s
