## Overview

Laylo appears to be an Android shopping app: users browse home and category listings, inspect items, and manage a cart, with login, registration, profile, and address UI also present. The tree identifies these screens and supporting adapters/models, but no runtime source or README was provided, so the workflow links below are dashed and unverified; their exact call order and persistence behavior cannot be established.

Main entry points: [`app/src/main/java/com/example/laylo/MainActivity.java`](https://github.com/hadeed1009/shopping_app/blob/master/app/src/main/java/com/example/laylo/MainActivity.java) (Main navigation), [`app/src/main/java/com/example/laylo/HomeFragment.java`](https://github.com/hadeed1009/shopping_app/blob/master/app/src/main/java/com/example/laylo/HomeFragment.java) (Home browsing), [`app/src/main/java/com/example/laylo/CategoriesFragment.java`](https://github.com/hadeed1009/shopping_app/blob/master/app/src/main/java/com/example/laylo/CategoriesFragment.java) (Categories), [`app/src/main/java/com/example/laylo/CartFragment.java`](https://github.com/hadeed1009/shopping_app/blob/master/app/src/main/java/com/example/laylo/CartFragment.java) (Cart)
