# 🖥️ RR3 Server URL Input System - Implementation Complete

**Date:** February 22, 2026  
**Status:** ✅ **IMPLEMENTED** - APK builds successfully  
**Build:** `RR3-ServerInput-Test.apk`

---

## 🎉 What's New

**First-Launch Server Configuration Dialog**

Users can now enter their custom server URL directly in the game on first launch - no APK rebuilding required!

---

## ✨ Key Features

### 1. **First Launch Experience**
- Game detects no server URL configured
- Shows dialog: "🏎️ Community Server Setup"
- User enters server URL (e.g., `http://192.168.1.100:5001`)
- Optional "Test Connection" button validates connectivity
- URL saved to device (SharedPreferences)
- Game continues normal boot with that server

### 2. **Subsequent Launches**
- Game reads saved URL automatically
- Direct boot to game - no dialog shown
- URL persists until user changes it

### 3. **Changing Servers**
- Can be implemented in Settings menu
- Call `CommunityServerManager.clearServerUrl(context)`
- Restart game → Setup dialog appears again

### 4. **Priority System**
```
1. 🥇 User input (SharedPreferences) - HIGHEST PRIORITY
2. 🥈 AndroidManifest.xml (fallback)
3. 🥉 EA default servers (last resort)
```

## 🔧 Technical Implementation

### Architecture Flow

```
Game Launch
  ↓
MainActivity.onCreate()
  ↓
Check SharedPreferences for "server_url"
  ↓
  ├─→ URL exists? → Continue boot → Use that server
  │
  └─→ No URL? → startActivityForResult(ServerSetupActivity, 0x1001)
        ↓
        [Server Setup Dialog Appears]
        ↓
        User enters URL → Test Connection (optional)
        ↓
        Tap "Continue" → saveServerUrl() → setResult(RESULT_OK)
        ↓
        MainActivity.onActivityResult()
        ↓
        RESULT_OK? → recreate() → Restart MainActivity
        ↓
        Now URL exists → Continue boot → Use custom server
```

### SharedPreferences Storage

**File:** `/data/data/com.ea.games.r3_row/shared_prefs/rr3_community_server.xml`

```xml
<?xml version='1.0' encoding='utf-8' standalone='yes' ?>
<map>
    <string name="server_url">http://192.168.1.100:5001</string>
</map>
```

### URL Validation

**Format check:**
- Must start with `http://` or `https://`
- Examples accepted:
  - `http://localhost:5001`
  - `http://192.168.1.100:5001`
  - `https://rr3.example.com`
  - `https://rr3.example.com:8443`

**Connection test:**
- Creates HttpURLConnection to `{URL}/director/api/android/getDirectionByPackage`
- 5-second timeout
- Shows "✅ Connection successful!" or "❌ Could not connect"
- User can continue even if test fails (for offline setup)

## 🔧 Developer Guide

### Adding "Change Server" to Settings Menu

**In SettingsActivity button handler:**

```smali
# Clear saved URL
invoke-static {p0}, Lcom/firemint/realracing/CommunityServerManager;->clearServerUrl(Landroid/content/Context;)V

# Show confirmation toast
const-string v0, "Server cleared. Restart game to reconfigure."
const/4 v1, 0x1
invoke-static {p0, v0, v1}, Landroid/widget/Toast;->makeText(Landroid/content/Context;Ljava/lang/CharSequence;I)Landroid/widget/Toast;
move-result-object v0
invoke-virtual {v0}, Landroid/widget/Toast;->show()V

# Kill process to force restart
invoke-static {}, Landroid/os/Process;->myPid()I
move-result v0
invoke-static {v0}, Landroid/os/Process;->killProcess(I)V
```

### Checking Current Server URL

```smali
invoke-static {p0}, Lcom/firemint/realracing/CommunityServerManager;->getServerUrl(Landroid/content/Context;)Ljava/lang/String;
move-result-object v0

# v0 now contains the URL or empty string
```

### Programmatically Setting URL

```smali
const-string v0, "https://rr3.example.com:8443"
invoke-static {p0, v0}, Lcom/firemint/realracing/CommunityServerManager;->saveServerUrl(Landroid/content/Context;Ljava/lang/String;)V
```

## 📊 Build Information

**Build Status:** ✅ Success

```
I: Using Apktool 2.10.0 with 12 thread(s).
I: Building resources...
I: Smaling smali_classes2 folder into classes2.dex...
I: Building apk file...
I: Built apk into: RR3-ServerInput-Test.apk
```

**Build Output:** `E:\rr3\rr3-apk\RR3-ServerInput-Test.apk`

**Next Steps:**
1. Sign APK with debug/release keystore
2. Test on device/emulator
3. Verify SharedPreferences creation
4. Test URL validation
5. Test connection test feature
6. Commit to Git

---

## 🔐 Security Considerations

### URL Validation
- ✅ Only accepts `http://` and `https://`
- ✅ Rejects `javascript:`, `file://`, etc.
- ✅ Input sanitization
- ✅ Connection timeout (5 seconds)

### Privacy
- ✅ URLs stored locally only (SharedPreferences)
- ✅ Not sent to analytics
- ✅ Not logged to logcat (only masked logs)
- ✅ User controls their own data

### Security Notes
- ⚠️ SSL validation disabled (by design for custom servers)
- ⚠️ Connection test sends test request to user-provided URL
- ⚠️ No protection against malicious servers (user trust model)
