Write an Android application - urgent :)

I need to develop app till the 20.1, and have 2 screens ready till the 10.1 so it's pretty urgent. Develop android app The app: roomies Goal: to manage the life of several roommates in the same apartment: - Home tasks (keeping track of who did what, counting how many times you did dishes, cleaned the house etc, and view of that info to the other roommates.) - Managing debts between the roommates (simple calculation of who pays to who) - Paying bills (adding bill to the app by data and calculate how much each needs to pay) - Managing shopping list (each of the roommate can add items, and each one can select if they want to participate in the purchase of it. eventually will calculate how much each one needs to pay relatively) - Achieving points and achievements (by completing task is the house like shopping twice a month, cooking 3 times a week, etc) There's should be integration between the users of the same house. There's a prototype ready, more details will be in a skype call Design architecture: MVS
