Can anyone help this engineering student to continue his j2me project?
Hi...Im doing project in J2ME...I got struck up in one module due to the problem of playing audio files..I wrote code and its playing fine in audio files like test-wav.wav and bark.wav..But if i use anyother audio file instead of test-wav.wav with the format like .mp3 and .wav...its playing but I cant hear the audio..I don know wat was the problem... i hav sent my code..Plz share ur idea and help me..The following code only im using now...
