Android connection error catch

[ViorelOnica]

I'm trying to establish a KNX connection using calimero library.

While using a public static void main, it's working just fine (code example below), but I'm having troubles trying to connect in an Android application.

Connection using public static void main (it works): `public class Main { private static final String remoteHost = "my_remote_ip_here";

  private static final String localHost = "my_local_ip_here";

  private static final String group = "0/0/1";
  private static final int knxServerPort = KNXnetIPConnection.DEFAULT_PORT;

/**
 * @param args
 */
public static void main(final String[] args) {
    KNXNetworkLink knxLink = null;
    ProcessCommunicator pc = null;
    System.out.println("This example shows how to establish a KNX connection "
        + "to a KNXnet/IP server.");

    try {
        final InetSocketAddress localEP = new InetSocketAddress(
            InetAddress.getByName(localHost), 0);
        final InetSocketAddress remoteEP = new InetSocketAddress(remoteHost, knxServerPort);

        System.out.println("Try connecting to " + remoteHost + " on port " + knxServerPort + "...");
        knxLink = new KNXNetworkLinkIP(KNXNetworkLinkIP.TUNNELING, localEP, remoteEP, true,
            TPSettings.TP1);

        System.out.println("Connection to " + remoteHost + " successfully established");

        knxLink.close();

        System.out.println("Connection got closed");
    }
    catch (final KNXException e) {

        System.out.println("Error connecting to " + remoteHost + ": " + e.getMessage());
    }

    catch (final InterruptedException e) {
        System.out.println("Connecting to " + remoteHost + " was interrupted, quit");
    }
    catch (final UnknownHostException e) {
        System.out.println("Host resolution for local endpoint " + localHost + " failed");
    }

}

}`

Connection in onCreate() (error catch):

`public class MainActivity extends AppCompatActivity { private static final String remoteHost = "my_remote_ip_here"; private static final String localHost = "my_local_ip_here";

private static final String group = "0/0/1";
private static final int knxServerPort = KNXnetIPConnection.DEFAULT_PORT;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    KNXNetworkLink knxLink = null;
    ProcessCommunicator pc = null;
    Log.d("asdf", "This example shows how to establish a KNX connection to a KNXnet/IP server.");

    try {
        final InetSocketAddress localEP = new InetSocketAddress(
                InetAddress.getByName(localHost), 0);
        final InetSocketAddress remoteEP = new InetSocketAddress(remoteHost, knxServerPort);

        Log.d("asdf", "Try connecting to " + remoteHost + " on port " + knxServerPort + "...");
        knxLink = new KNXNetworkLinkIP(KNXNetworkLinkIP.TUNNELING, localEP, remoteEP, true, TPSettings.TP1);

        Log.d("asdf", "Connection to " + remoteHost + " successfully established");
        knxLink.close();

        Log.d("asdf", "Connection got closed");
    }
    catch (final KNXException e) {

        Log.d("asdf", "Error connecting to " + remoteHost + ": " + e.getMessage());
    }
    catch (final InterruptedException e) {
        Log.d("asdf", "Connecting to " + remoteHost + " was interrupted, quit");
    }
    catch (final UnknownHostException e) {
        Log.d("asdf", "Host resolution for local endpoint " + localHost + " failed");
    }

}

}`

knxLink = new KNXNetworkLinkIP(KNXNetworkLinkIP.TUNNELING, localEP, remoteEP, true,TPSettings.TP1); After executing this line, error is catched, by the following catch block: catch (final KNXException e) { Log.d("asdf","Error connecting to " + remoteHost + ": " + e.getMessage()); }

I removed the real IPs in these examples, but everytime I'm trying to connect, I use legit IPs. I'd appreciate some help. Thank you!

Does your app have network permission in its manifest?

<uses-permission android:name="android.permission.INTERNET"/>
