getSupportActionBar error during android tutorial -


until now, able solve problems faced google search, can't find possible solutions problem.

(people sherlockactivity think these irrelevant mine, since looks independent api or library)

i assume it's library import, i'm not sure fix.

the error code prints: method getsupportactionbar() undefined type displaymessageactivity

on code: getsupportactionbar().setdisplayhomeasupenabled(true);

and added "android-support-v7-appcompat" library project , assured 1. it's library 2. it's in same physical location 3. yes there green tick.

like following: http://i.stack.imgur.com/jawwm.jpg

and build path of library set follows: http://i.stack.imgur.com/kex7i.jpg

if know how fix it, please me.

solution: getsupportactionbar() method getsupportactionbar() undefined type taskactivity. why?

your class needs extend actionbaractivity, rather plain activity in order use getsupport*() methods.
