基于DragonBord410C的智能遥控

前段时间公司有一个基于高通４１０c开发板的智能遥控项目，该项目的功能点如下：编码解析，编码学习，远程控制。下面我将为大家一一讲解这些功能的实现和ＡＰＰ的整体架构。

APP的架构：

发送Ｃｏｄｅ：

    public static void WriteData(String path, String content) {
        FileOutputStream fos = null;
        File file = new File(path);
        if (file.exists()) {
            try {
                fos = new FileOutputStream(file);
                Log.e("File", "FileWriter");
            } catch (FileNotFoundException e) {
                e.printStackTrace();
            }
            byte[] array = content.getBytes();
            try {
                fos.write(array);
            } catch (IOException e) {
                e.printStackTrace();
            }
            try {
                fos.flush();
                fos.close();
            } catch (IOException e) {
                e.printStackTrace();
            }

        }

    }

解析编码：

  public void onClick(View view) {
        switch (view.getId()) {
            case R.id.learn_mode:
                im.setVisibility(View.VISIBLE);
                message = new Message();
                cancle_learn.setVisibility(View.VISIBLE);
                cancle_learn.setEnabled(true);
                Config.WriteData(Config.LEARN_PATH, "1");
                timer.schedule(new TimerTask() {
                    @Override
                    public void run() {
                        String a = Config.Redata(Config.STATUS);
                        if (a.startsWith("0")) {
                           /* Config.Redata(Config.LEARN_PATH);*/
                            irCode = new ET4007IRDevice().readlearncode();
                            if (irCode.isValid()) {
                                irString = irCode.toString();
                            } else {
                                irString = "ERROR";
                            }
                            Bundle bundle = new Bundle();
                            bundle.putString("key", irString);
                            message.setData(bundle);
                            handler.sendMessage(message);
                            timer.cancel();

                        }

                    }
                }, 0, 1000);


                break;
            case R.id.mode_send:
                Config.WriteData(Config.SEND_PATH, irString);
                break;
            case R.id.cancle_learn:
                im.setVisibility(View.INVISIBLE);
                cancle_learn.setVisibility(View.INVISIBLE);
                setEnabled(false);
                timer.cancel();
                break;
            case R.id.save_value:
                 DialogUtil.launchdialog(this);
                break;

        }

主要用到的SO:

public class RemoteCore {
    private static final String libSoName = "IRCore";
    static {
        try {
            System.loadLibrary(libSoName);
            Log.e("JNI",libSoName+" load finished");
        }catch (Exception e){
            Log.e("JNI"," exception "+e.getMessage());
        }

    }





    public native static IRCode ET4007Learn(byte[] codes);

    public native static byte[] readLearnIRCode();

    public native static int IRinit();
}

OK，大功告成，简单的智能遥控就实现啦！
