After developed the game, how to insert the game to my phone for real testing?
Thank you!
What phone???
Nokia: N-Gage, 3120, 7610
Thank you very much~
The n-gage, you can simply bluetooth to (In Windows, send to->bluetooth)
The other 2 either the Nokia Connectivity Suite, or Oxygen Phone Manager II.
Thank you very much~
I just installed the software, but I forgot to buy the DKU-5 Cable 
But it is an easy job, I will buy it tomorrow. 
Also with the Nokia 7610, just send the JAD & JAR (or just the JAR) to it over Bluetooth. They’ll arrive in the Messages Inbox: open them, and the application installer will run and install them.
The DKU-5 cable is the easiest solution for the 3120. You can also install Over-The-Air by putting the JAD & JAR on a web site (which must have the MIME types correctly configured for types JAD & JAR), then opening the JAD file’s URL in the phone’s WAP browser.
Thanks for your reply~
If I use DKU-5 cable by using Nokia PC Suite, do I need to use “Install Application” for installing the game to the mobile phone?
My phone contains 447KB spaces, but my jar only consumes about 75 KB, but I don’t know why the Application Installer tells me “This application cannot be installed to the phone. The file is too big”??? ???
there is a 64 kb limit on jar files on many phones
But the original jar file consumed 63 KB already ???
My programs consumes 16KB, and my picture only consumes 6 KB, why it will be 76 KB after packaged?
The problem is solved after I opened a new Project and copied all the files from the old Project to the new Project.
