i'm trying make first android app using android developers myfirstapp guide i'm getting red flags in myactivity.java file

now have little experience in java code trying learn go along more practical learner find hard learn things books prefer visual references , physically doing im learning do. appreciated

what did the code

errors errors

first either have import android.support.v7.app.actionbaractivity or android.app.activity. if want use actionbaractivity need setup support library.

to solve other issue need fix intent so;

intent intent = new intent(this, displaymessageactivity.class);

because intent expects class knows launch displaymessageactivity.
