mAudioOutput.setOnItemChosenListener(new LabelledSpinner.OnItemChosenListener() {
@Override
public void onItemChosen(View labelledSpinner, AdapterView<?> adapterView, View itemView, int position, long id) {
String audioType = getResources().getStringArray(R.array.audio_output)[position];
switch (audioType) {
case "speakerphone": Flashphoner.getAudioManager().setUseSpeakerPhone(true); break;
case "phone":
