What happens? Exceptions? The program does not start?

You need to provide more information as we do not have time to build and debug your MIDlet on our devices...

Hello Hartti

I am not getting any exceptions or errors but even than the program is not executing. Its just showing a blank page.

Kindly check it once..

Thanks

You do not even get the Camera command in there?

Hartti

Hi,

Check and go through your code.It is due that your camera is not start yet.Or your camera is not ready to start.Check and debug the code.You can do so by your own.No one have so much time that he /she will make a project ,will compile and then testing.


make some system.out.println() or put break point out.

enjoyee
