J2ME

Zivjo

Kodo lahko pises v kateremkoli urejevalniku besedil (UltraEdit,Notepad,Vim,...), datoteko nato shranis kot datoteka.java
Upam da obvladas Javo, ker je le-ta temelj za delo z J2ME.

No pa vseeno en quick-tutorial:
Recimo da je datoteka datoteka.java ena delujoca aplikacija, sedaj pa postopek kako naredis jad in jar paket.

V Wireless Toolkit naredis nov projekt recimo mobile, v direktorij mobile/src pa skopiras datoteko datoteka.java,

Sedaj moras le se pritisniti (vse to v programcku Wireless Toolkit) gumb build, na koncu pa se run in se ti pozene emulator, kjer potem pritisnes launch v meniju.

Tako sedaj si zagnal aplikacijo.
Super to deluje.
Naresti moras le se jar(jad datoteko lahko najdes pod direktorijem (mislim da je bin))
to naredis tako, da zgoraj v meniju poisces build packet(nekaj takega) in jar paketek shrani tudi zraven datoteke jad se pravi v direktorij bin.

To je to. Sedaj le se jar in jad spravi na mobitel in more delovati. :)

bolj natancne informacije ti lahko dam, ko pridem domov

aja Javo, ki si jo downloadav more biti SDK in ne JRE (SDK pomeni standard development kit, JRE pa java runtime environment, poglej ce imas pod javaDIR/bin datoteko javac.exe, ce jo imas imas SDK)

Tukjle imas en primercek kako napises en applet
http://computer.howstuffworks.com/program.htm

Tukajle imas en tutorial kako napisati nekaj podobnega temu
http://developers.sun.com/techtopics/mobility/midp/articles/wtoolkit/

Tukajle pa se ena koda katero shrani v datoteka FirstMIDlet.java (ime datoteke mora biti enako imenu razreda (to je tisto ime zraven class))

//////////////DATOTEKA JE OD TU PA DO.....


import javax.microedition.midlet.*;
import javax.microedition.lcdui.*;
// A first MIDlet with simple text and a few commands.
public class FirstMIDlet extends MIDlet
implements CommandListener {

//The exit, info, and buy commands
private Command exitCommand;
private Command infoCommand;
private Command buyCommand;

//The display for this MIDlet
private Display display;

public FirstMIDlet() {
display = Display.getDisplay(this);
exitCommand = new Command("Exit", Command.SCREEN, 1);
infoCommand = new Command("Info-ka0",Command.SCREEN, 2);
buyCommand = new Command("Krneki", Command.SCREEN, 2);
}

// Start the MIDlet by creating the TextBox and
// associating the exit command and listener.
public void startApp() {
TextBox t = new TextBox("sverde21 tole rox;)",
"Welcome to MIDP Programming, no uglavnem tole je en tekst", 256, 0);
t.addCommand(exitCommand);
t.addCommand(infoCommand);
t.addCommand(buyCommand);
t.setCommandListener(this);
display.setCurrent(t);
}

// Pause is a no-op because there are no background
// activities or record stores to be closed.
public void pauseApp() { }

// Destroy must cleanup everything not handled
// by the garbage collector.
// In this case there is nothing to cleanup.
public void destroyApp(boolean unconditional) { }

// Respond to commands. Here we are only implementing
// the exit command. In the exit command, cleanup and
// notify that the MIDlet has been destroyed.
public void commandAction(Command c, Displayable s) {
if (c == exitCommand) {
destroyApp(false);
notifyDestroyed();
}
}
}



//////////////IN DO TUKAJ
prevedena datoteka po prej opisanem postopku je ena taka simpl aplikacija(deluje)
