How to start writing java mobile application?

Hello guys, I'd like to make a sudoku game or snake or w/e for my mobile phone but I have no idea where to start, anyone help me? ;)

Hey Koak,

This link looks interesting:

Free Games - Mobile Games@Midlet Review

You could download the .jar files and decompile them to see how its done ;)

Obviousally you will need a Java ME IDE to run these midlets.

Thanks, do you happen to have a good decompiler? :">

I personally use this. It works pretty well:

My license has expired already :(

What do you mean? You should be able to run this as a trial version. I\'ve used it for years and have never had to register it. Maybe the newest version is different?

It\'s only $19.99 to buy the full version. I strongly suggest buying it as it will stop all issues!

My parents won't let me make a paypal account :(

EDIT: tried another decompiler, it only decompiled half of the sudoku game :o

OK Koâk, no problem.

I have uploaded the version I have on my PC. Lets see if this works for you...

** link removed **

You will need winzip or winrar to open this compressed archive.

That didn't work either, but I've found a way to decompile them
only works if theyre Jarred tho :p

Thanks!

Wow confusing :o

Code :

    public final void a(f f1, byte byte0)
    {
        a_f_fld = f1;
        f1.a_c_fld = this;
        a_byte_fld = byte0;
        a_a_fld = a.a(a(a_java_lang_String_array2d_static_fld[a_byte_fld][Math.abs(a_java_util_Random_fld.nextInt()) % 40]));
        d = 4;
        e = 4;
        a_boolean_fld = false;
        a();
        a_f_fld.a(d, e, a_a_fld.a(e, d), (byte)(4 | (a_a_fld.a(e, d) ? 8 : 1)));
        a_long_fld = System.currentTimeMillis();
    }

all stuff like that, obfuscated? :o

OK cool. Glad you have found a way to decompile them..

That is your best bet. Then you can see exactly how they work and make any changes you want :D
