I am new to MIDlets development, but I wanted to try to develop simple MIDlet for my Nokia 6103. I used Carbide.j. I created a new class, then application package. Before creating application package I changed default device to "Prototype_4_0_S40_128x160_MIDP_Emulator". .jar and .jad files were created. I run successfully my MIDlet on an emulator. It worked fine. Then I transferred .jad file to my mobile. When I tried to execute it I got a message saying: "Invalid application. Delete?"
I guess, somehow, I have developed application for different device type. As I said, I wanted it to work on my N6103. What setting should I change?
I would appreciate any suggestions.
