我在Java中为Android编写了这个简单的代码，以通过以太网（WiFi）连接到KNX总线。不幸的是没有工作Android上的Calimero knx api停止工作
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;
}
}
此代码无法在我的android手机上运行。如果我运行它，该程序失败，并在我的android手机上显示消息“应用程序停止工作....”。但在PC上，类似的代码（doInBackground（）的内容）工作良好。正常工作意味着我能够在另一台计算机上接收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。
任何人都可以经历检查我的代码，并给我一个建议，问题在哪里？ calimero API使用正确的代码的一部分？这对我有所帮助。 Calimero API可以在Android操作系统中工作吗？有没有人有过这方面的经验（我认为是这样，根据论坛上的帖子）。

我尝试了一些调试尝试，错误发生在“新的TunnellingConnectionType（）“。 – vsm
