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:

<!-- 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:

<!-- 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)

✅ 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 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)

<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
