hi,all. I'm just a student. I'm interested in developing a java application for Nokia 7650/3650. I'm just a beginner. I want to ask some stupid questions:

1) I've downloaded Series 60 SDK for Symbian OS because the SDK includes a Nokia 7650 emulator. But I find that the EPOC Emulator does not look like 7650/3650, is it the same as 7650/3650??

2) I want to use J2ME + 7650 emulator. Can I do so?? and how?? because J2ME has already included an emulator.

3) I want to develop an application involving videos captured by the built-in camera. How can I test it using the emulator??

4) Is it possible to develop a live video chatroom, like netmeeting for mobile phone nowaday??

Thank you very much!!

1. I suggested you using J2Me Wireless Toolkit to develop
2. By using J2Me Wireless Tool Kit you can make your own Emulator. (If uyou need the document file i can send to you.)
Q3 and Q4 I'm also don;t know.
GOOD LUCK

Hello,

Nokia has created Series 60 platform as an licenseable package for PDA-like smart phones. The Nokia 7650 and Nokia 3650 are only the first examples of such phones. Our licensees (Siemens, Matsushita, Samsung) will most probably unveil their versions of Series 60 phones sometime in near future. This means naturally that the Series 60 emulator as a generic emulator doesn't look like any real phone (well, it could have, but that's the way the programmers decided anyway).

The good thing about Series 60 (and the same applies to our other series as well like Series 30, 40 and 80) is that there are a set of technical characteristics that are the same for all the phones in the series, whether they come form Nokia or any of the licensee. This means that you can create a game using Canvas (not FullCanvas as that's a Nokia extension) and it will look the same on all the Series 60 phones. All of them will also have a 5-way navigating device. On Nokia 7650 it's a small joystick and on Nokia 3650 it's a rocker pad. But programmatically it behaves in the same way.

2. You can create and run MIDlets on the emulator by downloading one of the two tools (or both):
- Nokia Developer's Suite 1.0 for J2ME? including Nokia 6310i MIDP SDK Beta 0.9 (from Forum Nokia Tools & SDKs)
- J2ME Wireless Toolkit 1.0.4 (from java.sun.com)

I suggest you get a proper development environment, like Sun ONE Studio Mobile Edition (from www.sun.com), which will make development and testing MIDlets much easier.

3. A MIDlet is not allowed to access files on Symbian OS.

4. The problem with a video chatroom is that a MIDlet doesn't have an API to access the camera. Otherwise a chat application is viable using HTTP connectivity. You can access the camera from Symbian/C++ programs.

Hi,

The forum listing says there are 2 replies to this post, but I can't see any, so I'll reply too. Sorry if I repeat infomation from others though.

1) It's similiar to a 7650, but is more generic. It's only supposed to be a generic series 60 emulator after all, but is the closest to a 7650 there is at the momen.

2) Yes, you can develop J2ME apps for the 7650, but you've got the wrong SDK. You need the Series 60 MIDP SDK Beta 0.1, available from the forum nokia download pages. The one you have will only let you develop apps in C++.

3) Well, you'll have a job on the emulator. You could probably find out more about the device camera from docs and things, then write the code that captures video and test that on a real device. Then you can code the rest of you apps using the emulator, and some video files put into the directory structure. Actually test the video capture stuff (if that's what you really want to do) wouldn't be easy on the emulator.

4) Technically, it's probably possible. The trouble with the 7650 (and 3650) is that the camera's point away from the screen (on the back of the phone!). Ignoring this fact, the device is probably powerful enough to support such things over a Bluetooth network. You'd have to really know your stuff to do such things over a GPRS connection though.

Hope this helps,

Steve
