How to connect activities (android studio 1.2) -


the biggest problem of tutorials earlier version of android - , solutions don't work on as1.2. , word "deprecated" confusing android newbie.

i'm trying simple app - mainactivity 1 menu option - settings.

so create new project (template blank activity) , new -> activity -> settings activity. when run app main activity appears on screen, menu has 1 option setting - doesn't work - expected, because didn't add code mainactivity. after 5 days of digging , copy pasting "solutions" i'm still on same point. no reaction - still have 2 not connected activities.

i'm sure have add code here:

 public boolean onoptionsitemselected(menuitem item) {         // handle action bar item clicks here. action bar         // automatically handle clicks on home/up button, long         // specify parent activity in androidmanifest.xml.         int id = item.getitemid();          //noinspection simplifiableifstatement         if (id == r.id.action_settings) {     // tb: here should setting activity shown             return true;         }          return super.onoptionsitemselected(item);     } }

the best code found (the clear):

if (id == r.id.action_settings) {   intent intent = new intent(this, settingsactivity.class);   startactivity(intent);   return true; }

but - no reaction...
