使用adk模式通过usb进行Android arduino通信

Question

我正在开发使用adk模式通信的android和arduino应用程序我已经在我的主要活动中实现了runnable，并且在运行方法中我正在读取值并且当读取完成时我正在向arduino板写入值并且通信运行无限我正在使用处理程序来更新GUI，但是应用程序在某段时间后停止了它的通信，我无法弄清楚是什么问题？处理程序中的GUI更新是否需要更多时间才能发生或其他任何事情？

以下代码用于接收和发送数据：

 while (true) { // read data
    try {
    int ret_read = 0;
    byte[] buffer_read = new byte[128];
    ret_read = mInputStream.read(buffer_read);

    for (int p = 0; p < 2 * (noOfFSensors); p = p + 2) {
    intListValues.add((int) composeInt(buffer_read[p],
                buffer_read[p + 1]));

    Log.d("Jankari", "Pu Value : "+String.valueOf((int) composeInt(buffer_read[p],
                buffer_read[p + 1])));

    }


      Message mPu = Message.obtain(mHandlerPuSensors);
      mPu.obj = new ValueMsgPuSensors("f", ret_read,intListFValues);
        mHandlerPuSensors.sendMessage(mPu);

    for (int a = 0; a < 2 * (noOfAnSensors); a = a + 2) {
    intListAnValues.add((int) (composeInt(buffer_read[2* (noOfFSensors) + a], 
                buffer_read[2* (noOfFSensors) + a + 1])));
    Log.d("Jankari", "An Value : "+String.valueOf(
         (int) (composeInt(buffer_read[2* (noOfFSensors) + a], 
    buffer_read[2* (noOfFSensors) + a + 1]))));

    }
    Message mAn = Message.obtain(mHandlerAnSensors);
    mAn.obj = new ValueMsgAnSensors("f", ret_read,
    intListAnValues);
    mHandlerAnSensors.sendMessage(mAn);

    for (int l = 0; l < noOfSw; l++) {
    intListSwValues.add((int) buffer_read[2* (noOfFSensors) +
        2 * (noOfAnSensors) + l]);
    Log.d("Jankari", "Sw : "+String.valueOf((int)
          buffer_read[2* (noOfFSensors) + 2 * (noOfAnSensors) + l]) );
    }
    Message mSw = Message.obtain(mHandlerSwSensors);
    mSw.obj = new ValueMsgSwSensors("f", ret_read,intListSwValues);
    mHandlerSwSensors.sendMessage(mSw);

        i += 1;


    mInputStream.close();

    // Send Output to arduino
    sendoutput();
       } catch (IOException e) {
      break;
    }

}

我正在使用的处理程序是

Handler mHandlerPuSensors = new Handler() {    
    @Override
    public void handleMessage(Message msg) {
        ValueMsgPuSensors msgPu = (ValueMsgPuSensors) msg.obj;
        txtReceivedBytes.setText("Received Bytes: " + msgPu.getRet());
        for (int i = 0; i < txtListFSensors.size(); i++) {
            txtListFSensors.get(i).setText(String.valueOf(msgPu.getFReadings().get(i)));
        }
        intListFValues.clear();         
    }
};
