RecordControl record.commit() NATIVE_ERROR: -2003

[Shaar]

Hello there!

From time to time I am getting such a exception while recording an audio/amr message:

java.io.IOException: NATIVE_ERROR: -2003
at com.nokia.microedition.media.protocol.OutputStreamWriter.commit(Unknown Source)
at com.nokia.microedition.media.control.RecordControl.commit(Unknown Source)

Here is my piece of code:

public void run() {
        Player myPlayer = null;
        RecordControl recorder = null;
        
        try {
            myPlayer = Manager.createPlayer("capture://audio?encoding=amr");
            myPlayer.realize();
            recorder = (RecordControl)myPlayer.getControl("RecordControl");
            
            ByteArrayOutputStream output = new ByteArrayOutputStream();
            recorder.setRecordStream(output);
            
            recorder.startRecord();
            myPlayer.start();
            long recordingTime = System.currentTimeMillis();
            long recordingEnd = System.currentTimeMillis() + this.messageLength;
            
            while ((recordingTime < recordingEnd) && !this.terminatedFlag) {
                int timeLeft = (int)(recordingEnd - recordingTime);
                this.recordingProgress.setValue(messageLength - timeLeft);
                
                try {
                    this.recordingThread.sleep(100);
                } catch (InterruptedException e) {
                    System.out.println("*debug* interrupting recording thread");
                    e.printStackTrace();
                    break;
                }
                
                recordingTime = System.currentTimeMillis();
            }
            System.out.println("*debug* MessRecorder: finished recording.");
            
            recorder.commit(); <---- Here the Exception occurs
            this.recordedSoundArray = output.toByteArray();

        } catch (MediaException me)  {
            me.printStackTrace();

        } catch (IOException ioe) {
            ioe.printStackTrace();
        } 

I have found that Native Error -2003 stands for KErrEtelNoCarrier "Problem communicating receiving device. Call was unexpectedly dropped".
The question is: what the No Carrier Problem has to do with audio recording ?

The code was tested on real devies (5800 XM and E52).

Got some idea how can I fix that?

Peter
