How to get the keycode for different mobiles using j2me - netbeans

Question

I am developing application for Nokia using Netbeans platform.
Now I am in idea to make this application to work on any java enabled mobile. So for that I have to get the platform of the devices, how can I get it(specifically for micromax, blackberry) mobiles? Also the left and right softkey code.

Answer 1

I found one answer which is given this link.
the KeyCodeAdapter class provided by above link is like below
import javax.microedition.lcdui.Canvas;
/**
* Class redefines codes of mobile phone to our constant values.
* Class can give to developers following information:
* <ul>
* <li/><i>defined platform name</i><br>
* In case if device vendor not defined we'll recieve <code>PLATFORM_NOT_DEFINED</code> like platform name.
* Same in this case keyCodes will be setted like for Nokia and SE. It's done for work on emulators,
* because on some of them it's impossible to define platform name.
* <li/><i>adopted to our constants key code value</i>
* <li/><i>for test returns defined real code of left softkey</i>
* </ul>

You have to use like this in your code:::-

switch (keyCode) {
case KeyCodeAdapter.SOFT_KEY_LEFT:
// some processing
break;
case KeyCodeAdapter.BACK_KEY:

break;

...
