Send SMS in Blackberry using J2ME

Hello,

When i had to implement this feature then i surfed a lot.I was new to Blackberry and J2ME.
I saw several posts but non was able to help me truely.

I gathered up the code and made it to work.
I had to send the message to the person whose call i missed up or to person whose incomming call is explicitly disconnected by me when i was busy.

The moment i disconnect the call, immediately a message is send to thta number.
That too should be done in a separate thread to avoid hang ups.

Hope it help someone. :)


Send SMS from Blackberry Application:

import java.io.IOException;
import javax.microedition.io.Connector;
import javax.microedition.io.Datagram;
import javax.microedition.io.DatagramConnection;
import javax.wireless.messaging.MessageConnection;
import javax.wireless.messaging.TextMessage;
import net.rim.device.api.system.RadioInfo;
public class SendSMS extends Thread {
    private String to;
    private String msg;
    public SendSMS(String to, String msg) {
        this.to = to;
        this.msg = msg;
    }
    public void run() {
        if (RadioInfo.getNetworkType() == RadioInfo.NETWORK_CDMA) {
            DatagramConnection dc = null;
            try {
                dc = (DatagramConnection) Connector.open("sms://" + to);
                byte[] data = msg.getBytes();
                Datagram dg = dc.newDatagram(dc.getMaximumLength());
                dg.setData(data, 0, data.length);
                dc.send(dg);
            } catch (IOException e) {
                e.printStackTrace();
            } finally {
                try {
                    dc.close();
                } catch (IOException e) {
                    System.out.println(e.getMessage());
                }
            }
        } else {
            MessageConnection mc = null;
            try {
                mc = (MessageConnection) Connector
                        .open("sms://" + to);
                TextMessage m = (TextMessage) mc
                        .newMessage(MessageConnection.TEXT_MESSAGE);
                m.setPayloadText(msg);
                mc.send(m);
            } catch (IOException e1) {
                e1.printStackTrace();
            } finally {
                try {
                    mc.close();
                } catch (IOException e) {
                    System.out.println(e.getMessage());
                }
            }
        }
    }
}

Send msg when call gets disconnected:
public void callDisconnected(int callId)
{
        final PhoneCall call = Phone.getCall(callId);
        final String number = call.getDisplayPhoneNumber();
        SendSMS sendSMS = new SendSMS(number, "message");
        sendSMS.start();
        super.callDisconnected(callId);
    }
You can try other methods also depending upon the requirements.

Custom Popups in Blackberry

Procedure:

1) Create a class that extends Popup .
2) In this class use your own manager
a) take one vertical field manager
b) add some text using label field and also a button inside this vertica field manager
c) And add vertical field manager in your screen


PopupScreen popup = new PopupScreen(new VerticalFieldManager());
popup.add(new LabelField("Hello!"));
popup.add(new ButtonField("OK"));


Create Border less Popup screen
PopupScreen popup = new PopupScreen(new VerticalFieldManager());
popup.add(new LabelField("Hello!"));
Border border = BorderFactory.createSimpleBorder(new XYEdges(), Border.STYLE_TRANSPARENT);
popup.setBorder(border);


Push popup screen:
UiApplication.getUiApplication().pushScreen(new MyPopup());

Closing a popup scren when uer clicks on Escape Key:
Need to implement Keychar method

popupscreen1=new PopupScreen(myverticalfieldmanager)
   {
        protected boolean keyChar(char c, int status, int time)
          {
               if (c == Characters.ESCAPE)
              close();
              return super.keyChar(c, status, time);
         }
   };
