Android上的Calimero knx api停止工作

Question

我用Java for Android编写了这段简单的代码来连接到KNX bus over Ethernet (WiFi)。不幸的是不能工作

public class MainActivity extends Activity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
 }

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.activity_main, menu);
    return true;
}

@Override
protected void onStart() {

    super.onStart();
    /*Pokus pro spojeni*/
    setContentView(R.layout.activity_main); 
    Button actButton = (Button) findViewById(R.id.button1); 
    int a=1;
    actButton.setText("1234" + Integer.toString(a));
    new NewComm().execute("Sending.....");
    Log.i ("MyTag","Starting.....");
  }
}

final  class NewComm extends AsyncTask<String, Void, Void>{

@Override
protected Void doInBackground(String... text) {

            String Enable = "Enalbe";
    String Disable = "Disable";
    String Address = "1/5/217";
    final CEMI_Connection tunnel;
    try {
        /* Create a new connection using CEMI_Connection
         *  to KNXnet/IP interface (in this case the ip
         *  192.168.1.3), with the default port
        */

        System.out.println("vsm> Connecting.....");
        tunnel = new CEMI_Connection(
                new InetSocketAddress("192.168.0.110",
                        EIBNETIP_Constants.EIBNETIP_PORT_NUMBER),
                        new TunnellingConnectionType());

        /* Just saying that it connected. In case of an error,
         *              
         *              
         * this is not executed, so you know it was unable to connect
         */
        System.out.println("Connected.");
        /* Create the knx device (a port from a relay for example)             
         *   and declare it as a boolean device, and it's a Enable/Disable             
         *   device. In the API docs there are all kinds avaliable 
        */

        PointPDUXlator object = PDUXlatorList.getPointPDUXlator(
                PDUXlatorList.TYPE_BOOLEAN[0],
                PointPDUXlator_Boolean.DPT_ENABLE[0]);

        /* Declare that we are going to write some info in the "Address"
         *              *  and this info is writed in the string Enable. To disable just
         *                            *  change the variable             
         */  

        object.setServiceType(PointPDUXlator.A_GROUPVALUE_WRITE);            
        object.setASDUfromString(Enable);

        /* Create the message to be sent to device
         * The device KNX address was declared in the begining
        */ 

        CEMI_L_DATA message = new CEMI_L_DATA(
                CEMI_L_DATA.MC_L_DATAREQ,
                new EIB_Address(),
                new EIB_Address(Address),
                object.getAPDUByteArray());
        /* Send the message using the connection "tunnel"
        */            
        tunnel.sendFrame(message, CEMI_Connection.WAIT_FOR_CONFIRM);

        /* Print that the message was sent
         */
        System.out.println("Message Sent to " + Address + ": " + Enable);

        /* Disconnect from the device and print it to the screen             
         * If your device can handle more than 1 Tunneling connection you             
         * can let it connected, but in my case I use different devices             
         * to control it, so I always have to disconnect after doing
         * anything             
         */ 

        tunnel.disconnect(null);
        System.out.println("Disconnected.");
        }        catch (EICLException ex) {
                ex.printStackTrace();
                System.out.println("vsm> Connection exception! "+ex.getMessage());
                    }  // connection error
    return null;

}


}

这段代码不能在我的android手机上运行。如果我运行它，程序会失败，并显示消息"application stop working....“在我的android手机上。但在PC上，类似的代码( doInBackground()的内容)运行良好。工作良好意味着我可以在另一台计算机上接收到KNX连接UDP数据包。

在Android设备上，我可以通过wifi发送简单的UDP数据包-这意味着wifi连接和Android Java中的基本代码正在工作。

有经验的人能检查我的代码并给我建议吗?问题出在哪里？使用calimero API的部分代码是否正确？这对我很有帮助。Calimero api能在android操作系统中工作吗？有没有人有这方面的经验(根据论坛上的帖子，我想是的)。

同样的问题也发生在我身上。您需要检查导入到项目中的jar文件，可以从以下位置执行此操作:YourProjectName(右键单击) -> Properties -> Java BuildPath -> Order -> export
