🏎️ RR3 APK Modification Tools + Server Browser
🎮 Real Racing 3 - Community Server APK Modifier
This repository contains tools to modify the Real Racing 3 APK to connect to community-hosted servers instead of EA's official servers. Perfect for game preservation, private servers, and offline play.
✨ NEW: Server Browser UI
No more rebuilding APKs! The new Server Browser feature lets users manage multiple community servers from within the game:
- 🌐 Multiple Servers - Save unlimited server profiles
- 🎨 Beautiful UI - WebView-based interface with real-time status
- ⚡ One-Click Connect - Switch servers instantly
- 🔄 No Reinstalls - One APK for all servers
- ⭐ Favorites - Mark frequently used servers
- 🔍 Connection Testing - Verify before saving
⚡ Quick Start
Basic APK Modification
# Simple URL redirect (old method)
.\RR3-Community-Mod.ps1 -ServerUrl "http://your-server-ip:5001"
Server Browser Installation (NEW!)
# Add server browser UI to APK
.\RR3-Server-Browser-Installer.ps1 -ApkPath "realracing3.apk"
# With pre-configured server

🔍 How It Works
Method 1: Simple URL Redirect (Original)
Real Racing 3 has built-in support for custom servers! Just change the configuration in AndroidManifest.xml:
<meta-data android:name="com.ea.nimble.configuration" android:value="custom" />
<meta-data android:name="NimbleCustomizedSynergyServerEndpointUrl" android:value="http://your-server:5001" />
Method 2: Server Browser (NEW!)
Adds a complete UI for managing servers:
- HTML/CSS/JS interfaces stored in APK assets
- Smali bridge code (CommunityServerManager) with JavascriptInterface
- SharedPreferences storage for server configs
- Patched game code to read active server URL at runtime
Result: One APK that can connect to any number of community servers!
