Required Mobile App Development freelancer for Developer needed to code a simple app on Android Studio job

So basically i'm making an app which shows you pizza coupons, I have already made the UI for both the start screens and the menu. I just need you to rig it up together via coding and also to add some features. These will be:

-Adding a system in which I can add discount codes to the app whenever I want and it will be updated for everyone.

-The user has to click on a certain 'Get Coupon' button after which the coupon will automatically be copied to one's clipboard.

-After the coupon has been copied, the app will open your default mobile browser and automatically make you go to website of the respective restaurant (there are only 3 restaurants) with my tracking ID embedded into the link.

These are fairly basic tasks and will require at most 2-3 hours. Let me know if you can do it and I'll be happy to hire you.

However make sure that the code is sleek and easy to understand for me.
