playTone and wav player doesnt work. (nokia 5320)

[spectra]

1. I dont know why, but playTone doestn work. I'm looking on specs (UAProfile) and I can see that this device understands x-tone-seq. (Device specifications : 5320 XpressMusic)

2. Trying to learn more about sounds in j2me and when app tryes to play sound, I see this error: java.lang.NullPointerException: 0

I suspect that the file you are trying to load is there in resource folder of the project...

i think just u check ur mobile phone ring tones if its working then there is no sound for gaming means ur media file only corrupted so u go to Nokia care center
