需求：测试android 设备以太网口的黄灯和绿灯是否正常
ThreadUtils.runOnSubThread(new Runnable() {
@Override
public void run() {
Log.d("coco","test network 1000m start.");
LinuxCommandRunner.exec("su");
LinuxCommandRunner.exec("ethtool -s eth0 speed 1000 duplex full");
Log.d("coco","test network 1000m end.");
}
});
ThreadUtils 就是个线程池工具，直接new Thread也可以。
LinuxCommandRunner就是执行linux指令的工具类。

if (exitCode == 0) {
Log.d(TAG,"Linux命令执行成功");
} else {
Log.d(TAG,"Linux命令执行失败");
}
return output.toString();
} catch (IOException | InterruptedException e) {
e.printStackTrace();
}
return null;
}
public static void exec(String command){
try {
Runtime.getRuntime().exec(new String[]{"sh","-c",command});
} catch (IOException e) {
