## 🔍 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
