+
+A centralized repository containing reusable **GitHub Actions workflows** designed to automate the Android development lifecycle. These pipelines handle tasks such as building APKs, running unit tests, linting code, and creating GitHub releases.
+
+---
+
+## Available Workflows
+
+| Workflow Name | File Name | Trigger | Description |
+| :--- | :--- | :--- | :--- |
+| **Build & Release APK** | `on_dispatch.yml` | `Tag Push (v*)` | Builds a Debug/Release APK, renames it, and uploads it to GitHub Releases automatically. |
+
+---
+
+##  How to Use
+
+To use any of these workflows in your Android project:
+
+1.  Create a `.github/workflows` directory in the root of your project.
+2.  Copy the desired `.yml` file content from this repository.
+3.  Paste it into a new file inside your project (e.g., `.github/workflows/release.yml`).
+4.  Configure the required **Secrets** (see below).
+
+---
+
+## Required Secrets
+
+Some workflows (like the **Release** workflow) require secrets to access external services (like APIs) or to sign the app.
+
+Go to `Settings` > `Secrets and variables` > `Actions` in your target repository and add:
+
+| Secret Name | Required For | Description |
+| :--- | :--- | :--- |
+| `NEWS_API_KEY` | `release.yml` | Your API Key for fetching news (injected into `local.properties`). |
+| `KEYSTORE_PASSWORD` | `release-signed.yml` | *(Optional)* Password for your signing Keystore (if using signed release). |
+| `KEY_ALIAS` | `release-signed.yml` | *(Optional)* Key alias for signing. |
+
+---
+
+## Example: Build & Release Workflow
+
+This is the standard workflow used to generate an APK and attach it to a release tag.
+
+```yaml
+name: Android Build & Release
+
+on:
+  push:
+    tags:
+      - 'v*'
+
+jobs:
+  build:
+    runs-on: ubuntu-latest
+    steps:
+      - uses: actions/checkout@v4
+      - uses: actions/setup-java@v4
+        with:
+          java-version: '17'
+          distribution: 'temurin'
+      
+      # Create local.properties with API Key
+      - name: Create local.properties
+        run: echo "NEWS_API_KEY=${{ secrets.NEWS_API_KEY }}" > local.properties
+
+      - name: Build APK
+        run: ./gradlew assembleDebug
+        
+      # Upload to Release...
