                        recorder.setAudioEncodingBitRate(8000);
  recorder.setAudioSource(MediaRecorder.AudioSource.MIC);
  recorder.setOutputFormat(MediaRecorder.OutputFormat.AMR_NB);
  recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
  recorder.setOutputFile(audiofile.getAbsolutePath());
  try {
   recorder.prepare();
  } catch (IllegalStateException e) {
  e.printStackTrace();
  } catch (IOException e) { 
  e.printStackTrace();
  }
  recorder.start();

Call recording is a special case which does not obey the same permissions or code paths. See this article . It seems to be deliberately made more difficult to do.
