# EA URL Elimination & Server URL Priority System

**Date:** February 22, 2026  
**Status:** ✅ EA URLs eliminated as primary, community server prioritized  
**APK Version:** v14.0.1

---

## 🎯 Problem Identified

The APK was configured to use EA's production "LIVE" servers as the default, with community server URL only as an override. This meant:
- Configuration mode: `LIVE`
- Default fallback: `https://syn-dir.sn.eamobile.com` (EA production)
- User config: SharedPreferences (only if set)

**Risk:** If SharedPreferences was cleared or not set, game would connect to EA servers (which are dead).

---

## ✅ Solution Implemented

Changed Nimble SDK configuration from `LIVE` to `CUSTOMIZED` mode, which prioritizes community servers.

### Changes Made

**File:** `E:\rr3\rr3-apk\AndroidManifest.xml`

**Line 126 - Changed configuration mode:**
```xml
<!-- BEFORE -->
<meta-data android:name="com.ea.nimble.configuration" android:value="live"/>

<!-- AFTER -->
<meta-data android:name="com.ea.nimble.configuration" android:value="customized"/>
```

**Line 127-128 - Added fallback URL:**
```xml
<!-- NEW -->
<!-- Community Server Configuration -->
<meta-data android:name="NimbleCustomizedSynergyServerEndpointUrl" android:value="http://localhost:5001"/>
```

## 🔄 Server URL Priority System

### Priority Order (Highest to Lowest)

```
Priority 1: SharedPreferences (User Configuration)
   ↓
   Location: /data/data/com.ea.games.r3_row/shared_prefs/rr3_community_server.xml
   Key: "server_url"
   Set by: ServerSetupActivity (first launch) or SettingsActivity (user change)
   Example: "https://rr3.example.com:5001"
   
   ✅ IF SET → Use this URL (return immediately)
   ⬇ IF NOT SET → Check Priority 2

Priority 2: AndroidManifest.xml (Compile-Time Default)
   ↓
   Meta-data: NimbleCustomizedSynergyServerEndpointUrl
   Value: "http://localhost:5001" (for local development/testing)
   
   ✅ IF SET → Use this URL
   ⬇ IF NOT SET → Check Priority 3

Priority 3: EA Defaults (DISABLED for CUSTOMIZED mode)
   ↓
   ⚠️ When configuration = "customized", EA URLs are NOT used
   ⚠️ Falls back to localhost:5001 from manifest
   
   LIVE mode URLs (DISABLED):
   - https://syn-dir.sn.eamobile.com (production)
   - https://director-stage.sn.eamobile.com (staging)  
   - https://director-int.sn.eamobile.com (integration)
```

## 📊 Configuration Modes

### NimbleConfiguration Enum Values

| Mode | Description | Default URL | Use Case |
|------|-------------|-------------|----------|
| `UNKNOWN` | Invalid/unset | None | Error state |
| `INTEGRATION` | EA dev environment | `director-int.sn.eamobile.com` | ❌ Never use |
| `STAGE` | EA staging | `director-stage.sn.eamobile.com` | ❌ Never use |
| `LIVE` | EA production | `syn-dir.sn.eamobile.com` | ❌ OLD (replaced) |
| **`CUSTOMIZED`** | **Community servers** | **Manifest or SharedPrefs** | ✅ **ACTIVE** |
| `MANUAL` | Manual override | None | ⚠️ Requires code |

**Current Mode:** `CUSTOMIZED` ✅

## ✅ Verification

### EA URLs Still Present (But Disabled)

EA URLs remain in the code as **string constants** but are **never reached** when:
1. User has configured a server URL (SharedPreferences) ✅
2. Configuration mode is CUSTOMIZED ✅
3. Manifest has fallback URL ✅

**EA URL References (All unreachable):**
- Line 19: `SYNERGY_INT_SERVER_URL` (constant, not used)
- Line 21: `SYNERGY_LIVE_SERVER_URL` (constant, not used)
- Line 23: `SYNERGY_STAGE_SERVER_URL` (constant, not used)
- Line 1008: `"https://syn-dir.sn.eamobile.com"` (in LIVE/UNKNOWN branch)
- Line 1041: `"https://director-stage.sn.eamobile.com"` (in STAGE branch)
- Line 1046: `"https://director-int.sn.eamobile.com"` (in INTEGRATION branch)

**Execution Path:** Lines 959→969→979→985 (return) → **EA URLs never reached** ✅

## 🧪 Testing Scenarios

### Scenario 1: Fresh Install (No SharedPreferences)
```
Boot → MainActivity → CommunityServerManager.checkServerUrl()
    ↓
    Returns: false (no server_url in SharedPreferences)
    ↓
ServerSetupActivity launches → User inputs URL → Saved to SharedPreferences
    ↓
Game restarts → getSynergyDirectorServerUrl()
    ↓
Priority 1: SharedPreferences found ✅
    ↓
Returns: User's custom URL
    ↓
Director API called: http://user-url/director/api/android/getDirectionByPackage
```

### Scenario 2: Returning User (SharedPreferences Exists)
```
Boot → MainActivity → CommunityServerManager.checkServerUrl()
    ↓
    Returns: true (server_url exists in SharedPreferences)
    ↓
Game continues boot → getSynergyDirectorServerUrl()
    ↓
Priority 1: SharedPreferences found ✅
    ↓
Returns: User's custom URL (e.g., "https://rr3.example.com:5001")
    ↓
Director API called successfully
```

### Scenario 3: SharedPreferences Cleared (Emergency Fallback)
```
SharedPreferences wiped → getSynergyDirectorServerUrl()
    ↓
Priority 1: Not found
    ↓
Priority 2: Check AndroidManifest.xml
    ↓
NimbleCustomizedSynergyServerEndpointUrl = "http://localhost:5001"
    ↓
Returns: "http://localhost:5001" (for local testing)
    ↓
Game tries localhost (development scenario)
```

### Scenario 4: Wrong Configuration Mode (Safety Check)
```
If someone accidentally changes configuration back to "live":
    ↓
Priority 1: SharedPreferences STILL checked first ✅
    ↓
Returns: User's custom URL (SharedPreferences override)
    ↓
EA URLs only used if BOTH Priority 1 AND Priority 2 fail
```

## 🔒 Security Implications

### Before (LIVE Mode):
- ⚠️ Fallback to EA production servers
- ⚠️ Potential data leakage to dead servers
- ⚠️ Connection failures if EA domains resolve

### After (CUSTOMIZED Mode):
- ✅ No automatic EA server connections
- ✅ User-controlled server selection
- ✅ Localhost fallback for development
- ✅ SharedPreferences override always works

---

## 📝 Configuration File Priority

### 1. Runtime Configuration (Highest Priority)
**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">https://rr3.example.com:5001</string>
</map>
```
**Managed by:** `CommunityServerManager.java`  
**Set via:** ServerSetupActivity (first launch), SettingsActivity (user settings)

### 2. Compile-Time Configuration (Fallback)
**File:** `AndroidManifest.xml` (inside APK)
```xml
<meta-data android:name="com.ea.nimble.configuration" android:value="customized"/>
<meta-data android:name="NimbleCustomizedSynergyServerEndpointUrl" android:value="http://localhost:5001"/>
```
**Managed by:** APK build process  
**Set via:** Editing manifest before APK build/sign

### 3. Hardcoded Defaults (Never Used)
**File:** `SynergyEnvironmentImpl.smali` constants  
**Status:** Present in code but unreachable with CUSTOMIZED mode ✅

---

## 🎯 Summary

### Changes Made:
1. ✅ Changed `com.ea.nimble.configuration` from `"live"` to `"customized"`
2. ✅ Added `NimbleCustomizedSynergyServerEndpointUrl` fallback to manifest
3. ✅ Verified SharedPreferences check happens FIRST (Priority 1)
4. ✅ Confirmed EA URLs are unreachable with current configuration

### URL Priority:
```
1. SharedPreferences (user config)    ← ALWAYS CHECKED FIRST ✅
2. AndroidManifest.xml (fallback)     ← localhost:5001 ✅
3. EA Servers (DISABLED)              ← Never reached ✅
```

### EA URL Status:
- **Present in code:** Yes (as string constants)
- **Reachable:** No ❌ (only if both Priority 1 AND 2 fail)
- **Risk level:** Minimal (triple-layered protection)

### Security:
- ✅ User-controlled server selection
- ✅ No automatic EA connections
- ✅ Safe fallback for development (localhost)
- ✅ Multiple layers of protection

---

**Status:** ✅ COMPLETE  
**EA URLs:** Effectively eliminated from execution path  
**Community Server:** Prioritized at all times  
**Next:** Rebuild & sign APK with new configuration
