Overview

This snippet demonstrates how to make a phone call by using a platform request. The MIDlet constructs a menu item through which the user can call the specified number. After the platform request has been made, the user is prompted whether he or she wants to make a voice call, a video call, or an Internet call.

Source

import javax.microedition.io.ConnectionNotFoundException;
import javax.microedition.lcdui.Command;
import javax.microedition.lcdui.CommandListener;
import javax.microedition.lcdui.Display;
import javax.microedition.lcdui.Displayable;
import javax.microedition.lcdui.Form;
import javax.microedition.midlet.MIDlet;
public class ExampleMIDlet extends MIDlet implements CommandListener {
private Command callCommand;
private Command exitCommand;
private Form mainForm;
 
// The phone number to call
private final String PHONE_NUMBER = "123456789";
 
/**
* Constructor. Constructs the object and initializes displayables.
*/

public ExampleMIDlet() {
mainForm = new Form("ExampleMIDlet");
 
callCommand = new Command("Call", Command.SCREEN, 0);
mainForm.addCommand(callCommand);
 
exitCommand = new Command("Exit", Command.EXIT, 0);
mainForm.addCommand(exitCommand);
 
mainForm.setCommandListener(this);
}
 
/**
* Calls the specified number.
*/

private void call(String number) {
try {
platformRequest("tel:" + number);
} catch (ConnectionNotFoundException ex) {
System.out.println(ex.getMessage());
}
}
 
/**
* Called when the MIDlet is started.
*/

public void startApp() {
Display.getDisplay(this).setCurrent(mainForm);
}
 
/**
* Called when MIDlet is paused.
*/

public void pauseApp() {
}
 
/**
* Called to signal the MIDlet to terminate.
*
* @param unconditional if true, then the MIDlet has to be unconditionally
* terminated and all resources has to be released.
*/

public void destroyApp(boolean unconditional) {
}
 
/**
* From CommandListener.
* Called by the system to indicate that a command has been invoked on a
* particular displayable.
* @param command the command that was invoked
* @param displayable the displayable where the command was invoked
*/

public void commandAction(Command command, Displayable displayable) {
if (command == callCommand) {
call(PHONE_NUMBER);
} else if (command == exitCommand) {
// Exit the MIDlet
destroyApp(true);
notifyDestroyed();
}
}
}

Postconditions

The user can select Call to call the specified number. He or she may also select whether the call should be a voice call, a video call, or an Internet call.
