从Android代码发送ACK到Hapi

Question

我正在创建一个Android应用程序，它作为一个监听器，等待监视器通过Wi-Fi通过HL7协议发送信息的代码。

我正在使用Hapi应用程序测试我的应用程序并收到消息，但我无法将ACK发送回Hapi测试面板。任何人都可以帮助我吗？

public void onCreate()
{
  super.onCreate();    
  serverThread = new Thread(new Runnable() {
    public void run()
    {
      try
      {
        PrintWriter mOut;
        Looper.prepare();
        socket = new ServerSocket(8080);
        socket.setReuseAddress(true);
        socket.setPerformancePreferences(100, 100, 1);

        while (!stop)
        {
          Socket accept = socket.accept();
          accept.setPerformancePreferences(10, 100, 1);
          accept.setKeepAlive(true);

          try
          {                                              
            in = new BufferedReader(new InputStreamReader(accept.getInputStream())); 

            //Each message has 15 segments
            int cont=0;
            for (cont=0;cont<15;cont++){
              if (cont==0){
                aux = in.readLine();
                aux=aux.substring(1);
                if (aux.contains(inicio)){
                  hl7Message=aux+separator2;
                }
                else{
                  Log.v("Fail", "Error, the received data does not " +
                      "follow the HL7 protocol");
                  break;    
                }
              }

              hl7Message+=in.readLine()+separator2;

              Log.v("hl7",hl7Message);
              ACK= hl7Parser(hl7Message);
              mOut.print(ACK);
              //Wait 5 minutes for the next message comming from the monitor 
              //while the conexion is available
              //Thread.sleep(INTERVAL);
            }
          }
          catch (IOException e2)
          {
            e2.printStackTrace();
          }

          displayNotification(hl7Message);
        }
      }
      catch (Throwable e)
      {
        e.printStackTrace();
        Log.e(getClass().getSimpleName(), "Error in Listener",e);
      }

      try
      {
        socket.close();
      }
      catch (IOException e)
      {
        Log.e(getClass().getSimpleName(), "keep it simple");
      }
    }
  },"Server thread");
  serverThread.start();
}

这就是我通过mOut发送ACK的方式：

public String hl7Parser(String hl7Message){

    String[]  fieldsOfMessage= null;
    fieldsOfMessage=hl7Message.split(separator2);
    //Message Header
    MSH=fieldsOfMessage[0];

    int[] indice;

    //MSH SEGMENT
    indice=get_indice(MSH);

    String sending_application, sending_facility, receiving_application, 
    receiving_facility, date, message_type, 
    message_control_id, processing_ID, version, sequence_number, 
    accept_ack_type, app_ack_type, country_code, principle_language, message_profile_id;


    sending_application=MSH.substring(indice[1]+1,indice[2]);
    Log.v("Sending_application",sending_application);

    sending_facility=MSH.substring(indice[2]+1,indice[3]);
    Log.v("Sending_facility",sending_facility);

    receiving_application=MSH.substring(indice[3]+1,indice[4]);
    Log.v("Receiving_application",receiving_application);

    receiving_facility=MSH.substring(indice[4]+1,indice[5]);
    Log.v("Receiving_facility",receiving_facility);

    date=MSH.substring(indice[5]+1,indice[6]);
    Log.v("Date",date);

    message_type=MSH.substring(indice[7]+1,indice[8]);
    Log.v("Message_type",message_type);
    int tr=message_type.indexOf("^");
    String type=message_type.substring(tr+1);

    message_control_id=MSH.substring(indice[8]+1,indice[9]);
    Log.v("Message_control_id",message_control_id);

    processing_ID=MSH.substring(indice[9]+1,indice[10]);
    Log.v("Processing_ID",processing_ID);

    version=MSH.substring(indice[10]+1);
    Log.v("Version",version);   

         ACK=inicio+"|"+receiving_application+"|"+receiving_facility+"|"+sending_application+"|"+sending_facility+"|"+standard_date+"||"+"ACK^"+type+"|"+message_control_id+"|"+processing_ID+"|"+version+"\n"+"MSA"+"|"+"AA"+"|"+message_control_id;

    return ACK;

 }


private int [] get_indice(String line){

        int l=line.length();
        char d='|';
        char[] letras = line.toCharArray();
        int[] indices = new int[1000];
        int s = 0;

        for (int i = 0; i < l; ++i)
        {
            if (d == letras[i])
            {
             indices[s]=i;
             s++;

            }
        }

        return indices;
     }

我已经尝试了但是我遇到了一些与java和android冲突相关的错误，这就是我试图这样做的原因，但是我把这个错误带到了测试面板中：
