Android :: How To Capture Video?

I would like to create a video recorder and so far haven't figured out how to set parameters in order to successfully go through MediaRecorder.prepare() method. Executing the following method

public void start() throws IOException{
String state = android.os.Environment.getExternalStorageState();
if(!state.equals(Environment.MEDIA_MOUNTED))
{
throw new IOException("SD card is not mounted. It is " + state + ".");
}
File directory = new File(path).getParentFile();
if(!directory.exists() && !directory.mkdirs())
{
throw new IOException("Path to file could not be created.");
}

recorder.setVideoSource(MediaRecorder.VideoSource.CAMERA);
recorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
recorder.setVideoEncoder(MediaRecorder.VideoEncoder.H263);
recorder.setVideoFrameRate(15);
recorder.setVideoSize(176, 144);
recorder.setOutputFile(path);
recorder.prepare();
recorder.start();
this.state = VideoRecorderState.STATE_RECORDING;
}

it throws an exception on line recorder.prepare(). Does anyone know how to set parameters in order to be able to capture video?
