Code sample to Send SMS from a J2ME application.

By: Leon in J2ME Tutorials on 2010年07月30日 [フレーム]

A java application, where on making a Push to talk call, and the call does not get matured due the the callers phone being busy in another call, busy in packet data, switched off or not in coverage, the java appplication installed in the callers phone should send out a sms, automatically to the called number. The number to send the SMS is taken from the phone book for the called number.

Here at at first we created a form called send sms and added commands to exit and send.

On clicking the send the control goes to public void sendit(String paramString1, String paramString2). where it first creates a connection with defined addree and and then creates an empty msg of type text. We then added the text that has to be sent and the pass that in the url of the address

 public void startApp()
 {
 this.display = Display.getDisplay(this);
 this.form = new Form("send sms");
 this.text = new TextField("number", "", 256, 0);
 this.send = new Command("send", 4, 1);
 this.exit = new Command("exit", 3, 2);
 this.form.append(this.text);
 this.form.addCommand(this.send);
 this.form.addCommand(this.exit);
 this.form.setCommandListener(this);
 this.display.setCurrent(this.form);
 }
 public void pauseApp()
 {
 }
 public void destroyApp(boolean paramBoolean)
 {
 }
 public void commandAction(Command paramCommand, Displayable
paramDisplayable) {
 if (paramCommand == this.exit) {
 notifyDestroyed();
 }
 if (paramCommand == this.send) {
 this.number = this.text.getString();
 System.out.println("in loop" + this.number);
 this.message1 = "please call me back";
 sendit(this.message1, this.number);
 }
 }
 public void sendit(String paramString1, String paramString2)
 {
 this.phoneNumber = paramString2;
 this.message = paramString1;
 StringBuffer localStringBuffer = new StringBuffer(20);
 String str = "sms://" + paramString2 ";
 this.form2 = new Form("");
 MessageConnection localMessageConnection = null;
 try
 {
 localMessageConnection = (MessageConnection)Connector.open(str);
 TextMessage localTextMessage =
(TextMessage)localMessageConnection.newMessage("text");
 localTextMessage.setAddress(str);
 localTextMessage.setPayloadText(paramString1);
 localMessageConnection.send(localTextMessage);
 this.form2.append("message sent");
 this.display.setCurrent(this.form2);
 }
 catch (Exception localException) {
 this.form2.append("phone number" + str + localException.getMessage());
 this.display.setCurrent(this.form2);
 }
 }
