+/**
+ * Android Release Script - Universal Version
+ * 
+ * Automatically builds Android APK and uploads to Gitea Release.
+ * 
+ * Features:
+ * - Auto-detect Android project root (standalone or monorepo)
+ * - Auto-detect Gitea config from git remote URL (HTTPS/SSH)
+ * - Auto-detect Java Home from Android Studio
+ * - Support tag-based release workflow
+ * 
+ * Environment Variables:
+ * - GITEA_TOKEN (required): Gitea API token
+ * - GITEA_API_URL (optional): Override Gitea API URL
+ * - GITEA_OWNER (optional): Override repository owner
+ * - GITEA_REPO (optional): Override repository name
+ * 
+ * Usage:
+ *   node release-android.mjs [--project <name>] [android-dir]
+ *   
+ *   --project <name>  Specify project name (e.g., admin-tool, android)
+ *   android-dir       Android project directory (optional, auto-detect if not specified)
+ * 
+ * Examples:
+ *   node release-android.mjs --project admin-tool
+ *   node release-android.mjs --project android ./android

+# Android Release Command
+
+Build Android APK and upload to Gitea Release for the current directory's Android project.
+
+## Prerequisites
+
+Before running this command:
+
+1. **Create and push the git tag first** (e.g., `myapp-1.0.0`, `android-1.0.0`, or `v1.0.0`)
+2. Ensure `GITEA_API_TOKEN` environment variable is set
+3. Ensure Android project exists in current directory
+
+Check the environment:
+
+```bash
+# Check GITEA_API_TOKEN
+echo "GITEA_API_TOKEN: ${GITEA_API_TOKEN:+SET}"
+
+# Check current directory for Android project
+ls -la app/build.gradle.kts 2>/dev/null || ls -la android/app/build.gradle.kts 2>/dev/null || echo "No Android project found"
+
+# Check recent tags (script will use the latest tag)
+git tag -l | tail -10
+```
+
+## Build and Upload
+
+After creating and pushing the tag, run:
+
+```bash
+node ~/.opencode/bin/release-android.mjs
+```
+
+The script will:
+- Auto-detect Android project root (standalone or monorepo)
+- Auto-detect project name from recent git tags or directory name
+- Auto-detect Gitea config from git remote URL (HTTPS/SSH)
+- Auto-detect Java from Android Studio
+- Build release APK
+- Upload to Gitea Release matching the tag pattern
+
+## Error Handling
+
+- If `GITEA_API_TOKEN` is not set: `export GITEA_API_TOKEN="your_token"`
+- If build fails: check Java/Android SDK installation
+- If tag not found: create and push the tag first
