看了幾天，發現ArduinoFrimata 這個project 使用的 AndroidSerialDriver 是2年前的版本

爬過最新版的AndroidSerialDriver 之後，把ArduinoFrimata 修改如下：

    private UsbSerialDriver usb_driver; // 改宣告以下變數
    private UsbManager usb_manager;
    private UsbSerialPort usb_port;
    public ArduinoFirmata(android.app.Activity context){
        //this.context = context;

        //this.usb = UsbSerialProber.acquire(manager); //原本是這樣寫
        this.usb_manager = (UsbManager) context.getSystemService(Context.USB_SERVICE); // 以下是這次修改的
        List<UsbSerialDriver> availableDrivers = UsbSerialProber.getDefaultProber().findAllDrivers(this.usb_manager);
        if (availableDrivers.isEmpty()) {
          return;
        }
        // Open a connection to the first available driver.
        this.usb_driver = availableDrivers.get(0);
    }

    public void connect() throws IOException, InterruptedException{
        if(this.usb_driver == null) throw new IOException("device not found"); // 從這邊開始修改
        
     // Find all available drivers from attached devices.
        
        UsbDeviceConnection connection = this.usb_manager.openDevice(this.usb_driver.getDevice());
        if (connection == null) {
          // You probably need to call UsbManager.requestPermission(driver.getDevice(), ..)
          return;
        }
		// Read some data! Most have just one port (port 0).
		this.usb_port = this.usb_driver.getPorts().get(0); //其他this.usb 也都更正為 usb_port 格式
        
        try{
            this.usb_port.open(connection);
            this.usb_port.setBaudRate(9600);
            Thread.sleep(3000);
        }
        catch(InterruptedException e){
            throw e;
        }
        catch(IOException e){
            throw e;
        }
        if(this.th_receive == null){
            this.th_receive = new Thread(new Runnable(){
                    public void run(){
                        while(isOpen()){
                            try{
                                byte buf[] = new byte[4096];
                                int size = usb_port.read(buf, 100);
                                SetLog("Read:"+HexDump.dumpHexString(buf));
                                if(size > 0){
                                    for(int i = 0; i < size; i++){
                                        processInput(buf[i]);
                                    }
                                }
                                Thread.sleep(10);
                            }
                            catch(IOException e){
                                close();
                                if(handler!=null) handler.onClose();
                            }
                            catch(InterruptedException e){
                                if(handler!=null) handler.onError(e.toString());
                            }
                        }
                    }
                });
            this.th_receive.start();
        }

        
        for (byte i = 0; i < 6; i++) {
        	byte[] writeData = {(byte)(REPORT_ANALOG | i), 1};
            write(writeData);
        }
        for (byte i = 0; i < 2; i++) {
        	byte[] writeData = {(byte)(REPORT_DIGITAL | i), 1};
            write(writeData);
        }
    }

總之，還有原本的版本是引用 google code 作為 submodule 我試著換成目前 github 的版本

應該會持續丟在這邊更新：https://github.com/jyyan/ArduinoFirmata-Android

我們明天見
