Events Application in Android with Firebase

I'll get straight to the point I need this within 7 days. - Android App written in Java and with Firebase. The app needs to have the following things - User login/registration. Registration will capture name, profile picture, dob, email, phone, gender, social media handles city and user type (admin or user although this is just last thing is temporary). There should also be a "forgotten password" function in here to reset the password. Once signed in, the user will either be diverted to an admin activity or a user activity. The activities will be identical except the admin activity has the extra ability to post new events whilst user can simply browse. On the homepage there will be a series of Netflix style horizontal rows which shows events that are nearest/recommended/most popular/saved/events the user bought ticket for already When you click on event it will go to event page here there needs to be displayed: jpg poster file, name, date, time, address with a map underneath where if you click it it will launch Google maps, dress code, price, number of tickets remaining if it is less than 10% of the total ticket number), save button and finally a buy a ticket option. For buying ticket, I would appreciate some of your previous experience to come in to play. I don't need a fancy QR code or anything like that (maybe a future thing?), Just some kind of ticket with a number would be good enough. For the admin side, it's the same but there should be a button to post new events. Them for the events they need to input all the data which would be required for the events page including the total number of tickets available for an event.
