## 🔍 Protocol Analysis Findings
|
|
|
|
### Communication Architecture
|
|
```
|
|
[Real Racing 3 APK]
|
|
↓ HTTPS (HttpURLConnection)
|
|
↓ Custom Headers (EAM-SESSION, EAM-USER-ID)
|
|
[EA Synergy Director] → https://syn-dir.sn.eamobile.com
|
|
↓ Service Routing
|
|
[Specialized APIs]
|
|
├─ synergy.product (Catalog)
|
|
├─ synergy.drm (Purchases)
|
|
├─ synergy.user (User Management)
|
|
└─ synergy.tracking (Analytics)
|
|
```
|
|
|
|
### Key Technical Details
|
|
- **HTTP Client**: Standard Java `HttpURLConnection`
|
|
- **SSL/TLS**: Custom certificate validation (CloudcellTrustManager)
|
|
- **Callbacks**: Native JNI for streaming responses
|
|
- **Format**: JSON for API, Protocol Buffers for ads
|
|
- **Headers**: `EAM-SESSION`, `EAM-USER-ID`, `EA-SELL-ID`, `SDK-VERSION`
|
|
- **Session**: UUID-based, 24-hour expiry

## 📈 Performance
|
|
|
|
### Resource Usage
|
|
- **Memory**: ~50-100 MB idle
|
|
- **CPU**: Minimal (<5% on modern hardware)
|
|
- **Storage**: SQLite database grows with usage (starts at <1 MB)
|
|
- **Network**: Handles 100+ concurrent connections
|
|
|
|
### Scalability
|
|
- Single server can support small communities (100-500 users)
|
|
- Horizontal scaling possible with load balancer
|
|
- Database can be migrated to PostgreSQL/MySQL for high load
|
