📱 USSD Automation with Delphi & Android - Complete Tutorial

Описание: 🚀 Learn how to automate USSD codes on Android using Delphi FireMonkey and Java Native Interface (JNI)!
In this comprehensive tutorial, I'll show you how to build a complete USSD automation application that can send USSD codes programmatically and receive responses on Android devices. Perfect for developers who want to integrate mobile banking, balance checking, or any USSD-based services into their Delphi applications!
🎯 What You'll Learn:
✅ Setting up Delphi for Android development
✅ Creating JNI bridges between Delphi and Java
✅ Accessing Android's TelephonyManager API
✅ Implementing callback interfaces for real-time responses
✅ Handling Android runtime permissions
✅ SQLite database integration for logging
✅ Building a modern FireMonkey UI
✅ Error handling and debugging techniques
✅ Dual-SIM support implementation
🛠️ Technologies Used:

Delphi RAD Studio (FireMonkey Framework)
Java (Android Native Development)
Android SDK (API Level 26+)
SQLite Database
JNI (Java Native Interface)
📋 Requirements:

Delphi RAD Studio 10.3 Rio or later
Android Device with Android 8.0+ (API Level 26+)
Android SDK installed
Basic knowledge of Delphi and Object Pascal
Understanding of Java basics (helpful but not required)

📖 Full Documentation: [GitHub README]
💾 Sample Database Schema: [Included in repo]
🔧 Android Manifest Template: [Included in repo]
📱 USSD Use Cases:
This technology can be used for:

Mobile banking automation
Balance checking systems
Airtime recharge applications
Service subscription management
Network diagnostic tools
Customer service automation
SIM toolkit applications

⚠️ Important Notes:

This requires Android 8.0 (Oreo) or higher
CALL_PHONE permission is required
USSD codes vary by carrier and country
Test thoroughly with your specific network provider
Some carriers may restrict programmatic USSD access

🐛 Common Issues & Solutions:
1️⃣ "API Level 26+ required" → Update your Android device
2️⃣ Permission denied → Grant CALL_PHONE permission
3️⃣ Network timeout → Check your network connection
4️⃣ Java bridge not initialized → Verify Java file placement
💡 Pro Tips:

Always handle callbacks asynchronously
Implement proper error handling
Log all transactions for debugging
Test with multiple carriers
Use background threads for database operations
Implement retry logic for network failures
