I need a android app with a navigation pan on the left to show categories. Once I tap a specific categories, I need to call an API which returns a set of lat/lang's and those needs to be shown with the category icon on the map. I should be able to select the radius using a radius tab on the categories navigation pane to be able to limit the search window. This project is going to be a continuation one once this feature is satisfied.
As show in below attachment, I need the lat/lng information from backend information to persist in the app and when a specific category lat/lang is clicked, I should be able to see the details of the category below in the map as a text page.
