i've tested the code that you've given , and it works fine. try changing the "extends SimonSaysActivity " to simply "extends Activity " and see for yourself that it works .

the reason that it doesn't work is either SimonSaysActivity doesn't extend Activity (which i don't think you've made this mistake) , or the order of the build path is wrong .

to go to the order of the build path , go to :

project->properties->Java build path->order and export .

my basic order is : project src , project gen , android 4.0.3 , android dependencies .

this problem usually occurs when you use libraries .
