Hi, I am using android studio and API 21 to follow this course. I found some navigation is deprecated. Should I make a fix or ignore them? Thanks.
final ActionBar actionBar = getSupportActionBar(); //It shows deprecated!! actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);

This will mean changing theme to holo instead of appCompat and a few other imports but it will help you follow the class in the long run.
