Getting Cell ID in Java ME

When the MIDlet is run in either a Series 40 or S60 device, a cell ID should be shown on the Form (one will have a numeric value and another will have 'null').


import javax.microedition.midlet.*;
import javax.microedition.lcdui.*;

public class CellIDMIDlet extends MIDlet implements CommandListener {
private Form form;
private Command exitCommand;
private String S40_cell_id; // Series 40 cell id property
private String S60_cell_id; // S60 cell id property
public void startApp() {
form = new Form("Getting Cell ID");
S40_cell_id = System.getProperty("Cell-ID");
S60_cell_id = System.getProperty("com.nokia.mid.cellid");
form.append("Series 40 devices: " + S40_cell_id + "\n");
form.append("S60 devices: " + S60_cell_id);
exitCommand = new Command("Exit", Command.EXIT, 1);
form.setCommandListener(this);
form.addCommand(exitCommand);
Display.getDisplay(this).setCurrent(form);
}
public void pauseApp() {
}
public void destroyApp(boolean unconditional) {
}
public void commandAction(Command c, Displayable d) {
if (c == exitCommand) this.notifyDestroyed();
}
}
