Android Studio Task

Good day, can you help: the task at university is to create a prototype with 15 pages in Android Studio, and we already have a prototype that we can send as a screenshot or as a prototype in the Pencil program (in English). It is simply necessary to make a similar one in Android Studio and download the zip archive and apk, but we cannot download the apk (it is grayed out and not clickable). Here is the initial task description, not very long:

The app obtained as a result of this exercise should not be final; it remains a prototype, so some aspects should not be identical to the real app (data updates, notifications, alerts, etc.).

The prototype on the news topic is simple, we will add text with a description

How much will it cost and when can it be done?

Thank you
