How to dynamically change launcher icon and name in Android?

Question

My small app aims to dynamically change the app icon and name seen in the homescreen based on the value of JSON with on-prem key. The code below changes the app icon seen in the running apps tab and app name seen in the application UI. However it does not change the app icon and app name seen in the homescreen. How should I modify it to handle the issue? Thank you. Also there is full project if it helps: github.com/beyzaozbay/white-label
