Android: Mediarecoder is throwing IllegalStateException in start()

I want to use the mediarecorder in my app to record voice. I do exactly what is described under http://developer.android.com/reference/android/media/MediaRecorder.html but the exception is always thrown in the start() method. The code should be fine, as I also tried out the code example called Mediarecorder from google but I get the same exception:

mRecorder = new MediaRecorder();
mRecorder.setAudioSource(MediaRecorder.AudioSource.MIC);
mRecorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
mRecorder.setOutputFile(mFileName);
mRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);

    try {
        mRecorder.prepare();
    } catch (IOException e) {
        Log.e(TAG, "prepare() failed");
    }
    mRecorder.start();

I have already added the permissions (android.permission.WRITE_EXTERNAL_STORAGE and android.permission.RECORD_AUDIO) to the AndroidManifest.xml, and I start the app on my connected smartphone.

Does anybody know what might cause the Exception and what one has to do?

Thanks for your comments. I was able to resolve the issue. I had in fact a missing mRecorder.release() and so it seems that the start method was called twice.
