I started yesterday with developing app on Android Studio and I am not sure how to declare my activity in AndroidManifest. I read the post on https://stackoverflow.com/questions/19122386/activity-declaration-in-androidmanifest-xml but I am still not sure what to put for the name and label and how to find their exact names. I would really appreciate your help and thank you.
