Symbian Java Programming for Idiot

[Edgedale]

I am interested to write a super simple app for keep track all birthdays, anniversaries, etc and link with the Calendar from the phone.

Any ideal how can i do it?
===========================================

I also wish to try writing a simple app. maybe like the one in palmOS's memo pad. HOW TO DO IT?

Use what to write? what to compile, any wysiwyg editor?

AFAIK, the p800 is the way to go.
see sun's web site for javaphone specs.

once you choose the target phone, you would typically download the SDK for the language you plan to use on the phone's manufacturer web site.

My target phone is 7650. I have the SDK kit but still i don't know how to start with... :-?

[amaher]

Could U find a way to begin with java for 7650?. if so pls let me know as i am trying to begin as well and i am lost!.

cheers

Haven't got a lot of time at the moment but...

If you're looking to program in Java there are a few things you should probably know before you spend the effort in learning:

1. You won't be able to access the internal functions of the phone such as bluetooth, camera and calendar.
2. All java programs are loaded through the machines JVM which means you have to go through Tools:Apps on the phone in order to start them (no auto start on turning the phone on etc.)
3. You can right some cracking games in the language!

Personally I've stopped writing Java stuff as it's a bit limited for the sort of thing I'm doing (business apps etc. - better off using C++ Symbian though it's hard work!), but if you just want to write a few games it's much easier to get on with than C++ (and if you haven't done any object orientated programming before it's a great palce to start).

I'll try to get a 'HelloWorld' type of example down on this thread later when I have more time.

In the mean time make sure you have the J2ME wireless toolkit downloaded from java.sun.com as you'll need it.

I had downloaded and installed, try run the appl and total LOST... wtf is J2ME wireless toolkit use for? It's a compiler or a editor?

[wahchild]

It's a compiler + all the libraries needed for generic J2ME (and some other stuff) - the most important bit is a small exe called KToolBar - This is very useful when setting up projects, it will compile your code for you and allow you to try it out in one of the in-built emulators. Once your done you cqan then just copy the jar file to your phone for use.

I'll try to get some examples up before the end of the day.

Here's the setup that can get you started on Symbian Java (or any other MIDP Java programming)

1. download J2SE (Standard Edition) 1.4.1 from java.sun.com, install it.
(this is the compiler environment)
2. download Sun ONE Studio, Mobile edition.
(this is the editing environment)
3. download the Nokia Series 60 MIDP SDK from forum.nokia.com, install it (this is extended classes for use with your series 60 phone, like fullscreen, audio support etc.)

When you have installed everything, (be sure to read the install instruction PDF's that come with most of these programs), start up Sun ONE Studio, click Help, then the Learning menu and Examples | Tutorials.

Scroll down to the Mobile Edition tutorials with the Converter app, download the pdf and zip file and follow the PDF to the point, you will need every piece of knowledge in this file in order to learn how to write and compile a MIDlet successfully, if you have never had experience with it before.

Sun ONE studio also comes with a host of examples applications that are very useful for getting used to the interface and classes.

A most Basic MIDlet suite in my opinion, is creating a MIDlet suite, adding a MIDlet class in it, and a MIDlet Canvas class, which is the 'drawing area' of your application (where the MIDlet is the program containing menu's etc.. there are examples of this in the Studio)

Hope you get it working!

Apa.
