Hi,
I'm a mobile sound producer specialized in mobile sound production.
I would like to play a RMF file on targeted mobiles, using JAVA technology, but I
can't find any example of a *.java file.
I' m using a "PlayWav.java" source file and I have changed in the code, the "WAV
informations" by the "RMF ones" . I built the project and packaged the .jar file using the Wireless Toolkit and all seems ok.
Naturally the file didn't paly in the phone emulator because it's not linked to RMF
on PC. It would play on targeted phones but I have to test.
Could you tell me if the code below is ok or not:
From the code writen to play a WAV file I have only changed the file
name/extension and mime type and replaced it by the RMF's ones ( at the end of code).
Could you tell me if it's ok in theory or if I have to make more than change the name/exctension and mime type of WAV file by RMF's ones ?
