Please visit the following Recording tutorial

This part in particular: 

String state = android.os.Environment.getExternalStorageState();
if(!state.equals(android.os.Environment.MEDIA_MOUNTED))  {
    throw new IOException("SD Card is not mounted.  It is " + state + ".");
}

// make sure the directory we plan to store the recording in exists
File directory = new File(path).getParentFile();
if (!directory.exists() && !directory.mkdirs()) {
  throw new IOException("Path to file could not be created.");
}

recorder.setAudioSource(MediaRecorder.AudioSource.MIC);
recorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
recorder.setOutputFile(path);
recorder.prepare();
recorder.start();

Furthermore it is not strictly necessery to record a file to run an sound level check, as stated here
