However, I have no idea with javadoc directory goes for each device(Or maybe I need to set a different one for each jar file?). Can anyone give me a clue? Good luck. I worked for three months with Eclipse and I was not able to figure out, how to solve this problem. For J2ME development Netbeans MobilityPack is way better than Eclipse.

My current guess tells me that: DefaultColorPhone is for cellphones who support color. DefaultGrayPhone is for older monochrome cellphones. QwertyDevice is for orginizer like cellphones with actual keyboard. And I think MediaControlSkin is either for testing purposes(which makes no sense, but that's what the name suggests), or for third generation cellphones. Am I right? Hm, I don't know, never thought about it. I'm just using the DefaultColorPhone for prototype testing and the emulators of the different vendors (Nokia, Motorola, Sony Ericson, Siemens/BenQ) which can be downloaded for free on the vendors websites.

If they are equal (or newer) it is supposed that your MIDlet runs on the other device. But keep in mind that other devices have different resolutions, different amount of memory and different processors. If you want to be sure your MIDlet runs on a specific mobile phone, you have to test it on the real device. Quote:Original post by someboddy 4) Can I safely assume that a MIDlet who works on the emulator will work on an actual cellphone? No! Sometimes it even happens, that it's not working in the emulator but on the real device. Quote:Original post by someboddy 5) Does the emulator limit the memory and the cycles per seconds of the MIDlet to mimic a realcell phone? Depending on the emulator. The emulators from Motorola are quite good because the emualtors are just an image of the firmware from the real device. But still it's not granted that your application also works on the real device. Usually MIDlets runs a bit faster in the emulator.
