Write an Android application

I need an app where users can [Search] for a company. Once the company is found, users can click to view [Overview] [Recent] [Services] [Locations] [Contact] On the Overview page, details about the company will be available, including mandate and logo. On the Recent page, users can view recent Twitter threads or Facebook posts by the company. On the Services page, users can view all services offered by the company. Clicking on a service allows the user to view information about the service, including cost, processing times etc. Users can view all steps or procedures for a particular service or application. (Registered users can view this list as an interactive checklist that can be saved) Users can select an option that sends the relevant forms to their emails. On the Locations page, users can view all branch locations or search for locations by city name. On the Contact page, contact information for the company headquarters will be presented with a link to find contact info for a specific branch. Users can send emails to the company or call any numbers available. On the backend I should be able to edit the database of companies and their information.
