## Overview

This repository is an Android sample-app template paired with a GitHub Actions APK-building workflow. A developer customizes the app and pushes the project; the documented workflow builds APKs that can be downloaded as artifacts. The sample app’s documented user-facing features are a Material-style responsive interface, click counter, and periodic toast notifications. Source excerpts were limited to the top-level Gradle file, so app and workflow connections below rely on README statements rather than inspected runtime implementation.
