## Overview

This repository is a learning collection of Android practicals, not one integrated application. The README documents small apps that teach UI basics, input-driven interactions, device features, web content, remote data, and sign-in. The available source tree also contains a separate Tutorial 13 Android app, but its implementation was not sampled, so its behavior and internal connections cannot be established. Tutorials stored as archives are represented only at the documented capability level.
