How to convert Wav file in to byte array an vise vers into RMS???????????

Question

hi Constantinos Loizou
i m having same problem which u were facing in last month.
my problem i have to save .WAV file into RMS and then retreive it from RMS.
my Code is
Read From RMS
RecordStore rsUser = RecordStore.openRecordStore(file,true);
if(rsUser.getNumRecords() > 0)
try {
byte[] byusrinfo = rsUser.getRecord(1);
InputStream in = new ByteArrayInputStream(byusrinfo,0,byusrinfo.length);
p = Manager.createPlayer(in,"audio/x-wav");
p.start();
return true;
catch(Exception ex) {
ex.printStackTrace();
return false;
rsUser.closeRecordStore();
catch(Exception ex) {
ex.printStackTrace();
return false;
Write in RMS
try {
RecordStore rsUser = RecordStore.openRecordStore(file,true);
int idata = is.available();
byte[] exdata = new byte[idata];
is.read(exdata);
if(rsUser.getNumRecords() > 0) {
rsUser.setRecord(1,exdata,0,exdata.length);
else {
rsUser.addRecord(exdata,0,exdata.length);
rsUser.closeRecordStore();
catch(Exception ex) {
ex.printStackTrace ();
now i have the file successfully when i retrieve it from RMS and p.reliaze() give me exception
javax.microedition.media.MediaException: Failed to realize Player: Malformed wave media: expected 'RIFF'
have u able to solve it. if yes then pls give me solution. or give other solution if this soution is not good

Well, I'm not going to give you your code on a silver platter. You'll need to put some effort in it yourself.
So look at that available() method yourself an see if you can improve on that. Look at the api docs, there is loads of information there, and often it will give you pointers on why things are not working.
