My project works on emulators but not on mobile devices (no image and on Samsung it says "unsupported file").
Please help, I don't know what to do. My configurations: MIDP 2.1, CLDC 1.1.
Thanks in advance.
Edit: I succeeded to solve it accidentally. I did the following: Sign the jar in Netbeans, clean and build, the jar didn't work, I wiped out the .ks from the jar and clean and build again. Now it worked.
