Daniel Elliott 61ad8db705 Eliminate EA URLs: Change config to CUSTOMIZED mode
- Changed com.ea.nimble.configuration from 'live' to 'customized'
- Added NimbleCustomizedSynergyServerEndpointUrl fallback (localhost:5001)
- EA production URLs no longer reachable in execution path

URL Priority System (enforced):
1. SharedPreferences (user config) - ALWAYS CHECKED FIRST 
2. AndroidManifest.xml (localhost fallback) 
3. EA Servers (unreachable with CUSTOMIZED mode) 

Security improvements:
- No automatic EA server connections
- User-controlled server selection enforced
- Triple-layer protection against EA fallback
- Safe localhost fallback for development

Files modified:
- AndroidManifest.xml (lines 126-128)

Documentation:
- EA-URL-ELIMINATION.md (complete analysis)
- RR3-NETWORK-ANALYSIS-AND-CONFIG-SYSTEM.md (updated)

Next: Rebuild APK to apply configuration changes

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
