Can't accesses setting activity (SharedPreferences)

view story

http://stackoverflow.com – When I run my application there is no menu button to go to the settings activity. I have a settings activity which uses shared preferences. I call in the Main Activity like this: private SharedPreferences settings; private OnSharedPreferenceChangeListener listener; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); settings = PreferenceManager.getDefaultSharedPreferences(this); listener = new OnSharedPreferenceChangeListener() { @Override public void onSharedPreferenceCha (HowTos)
