Updating my android app to support new api

Hello I need someone to update the source code of my android app to support some changes to the api it connects to. Most of the work is mapping to the updated endpoints and updating the data models, the data itself is largely the same, I don't see the general application logic changing much, and the layouts need only minimal updates to support the new api (which is fully documented in swagger). I built the backend and the api in php but i'm not familiar with java/kotlin enough to make the changes on the front end.
