MediaRecorder crashes on start

Question

i\'ve searched many topics but no straight answer.

I have this code :

        recorder = new MediaRecorder();
    recorder.setAudioSource(MediaRecord         


        

Answer 1

Try putting the start function in the same block as prepare function. maybe there's an exception blocking prepare from executing and goes directly to start thus causing an IllegalStateException.

    recorder.setAudioSource(MediaRecorder.AudioSource.MIC);
    recorder.setOutputFormat(output_formats[currentFormat]);
    recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
    recorder.setOutputFile(getFilename());


    try {
        recorder.prepare();
        recorder.start();
    } catch (IllegalStateException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    }

Answer 2

Try to start your recorder only when it is prepared :

    try {
        recorder.prepare();
        recorder.start();
        mStartRecording = true;
    }  catch (IOException e) {
        Log.e( LOG_TAG, "Error when preparing or starting recorder", e);
    }
