Having trouble with the Estimote "Airport" example app

I am getting code errors in Android studio for all lines with R.layout.activity_main
The error is on the R. Can someone please help? Below is a few lines of the code. Thanks. -Josh

private BeaconManager beaconManager;
private Region region;

protected void onCreate(Bundle savedInstanceState) {

Are you sure you chose “Blank Activity” when creating a new project, and not “Empty”?

I don’t have the option for “Blank Activity”. Is there another option that will work?

After I changed the Android Manifest the error on the “R.” lines changed to errors on the following 2 lines:

getMenuInflater().inflate(R.menu.menu_main, menu); (The error is on the first “menu”)

if (id == R.id.action_settings) { (The error is on “action_settings”)

Both errors say “cannot resolve symbol”.
