Add native Android barcode scanner app for Datalogic terminals

[Copilot]

Implements a native Android application for Datalogic terminals to scan barcodes, collect quantities, and export data to text files in the Download folder.

Implementation

Core Functionality

• MainActivity.java: Implements ReadListener for Datalogic SDK barcode scan events
• Quantity input field with numeric validation (defaults to 1 on invalid input)
• In-memory collection of scan entries (barcode + quantity pairs)
• Export to tab-separated text files with timestamp-based naming

Storage Strategy

• Android 10+ (API 29+): App-specific external storage (getExternalFilesDir()) - no permissions required
• Android 5-9 (API 21-28): Public Downloads directory - requests WRITE_EXTERNAL_STORAGE

UI Components

• Quantity input (EditText with number validation)
• Real-time scan list (ScrollView with TextView)
• Save and Clear action buttons

Android Studio Compatibility

The project is fully compatible with Android Studio and uses modern Gradle configuration:

• Project Location: Open the android-app/ folder in Android Studio
• Gradle: Modern plugin DSL syntax with Android Gradle Plugin 8.0.2 and Gradle 8.0
• Setup Guide: Comprehensive ANDROID_STUDIO_GUIDE.md included with step-by-step instructions
• Template: local.properties.example for SDK path configuration

Note: Requires Datalogic SDK (pre-installed on Datalogic devices) for barcode scanning functionality. Build configuration uses compileOnly dependency since SDK is provided at runtime by device firmware.

@copilot where do I find the projct files? Can you convert to be compiled in Android Studio?

The project files are in the android-app/ directory. The project is now fully compatible with Android Studio.

To open in Android Studio:

1. Launch Android Studio
2. Click "Open" and select the android-app folder
3. Android Studio will automatically detect and sync the Gradle project

I've added a comprehensive Android Studio Setup Guide with detailed instructions including:

• How to locate and open the project
• First-time setup steps
• Adding the Datalogic SDK
• Building and running on a device
• Troubleshooting common issues

The Gradle configuration has been modernized to use the latest plugin syntax for better Android Studio compatibility.
