# SynergyEnvironmentImpl.smali Patch

This patch modifies the game to check for community server URLs before using EA's servers.

## Location

File: `smali/com/ea/nimble/SynergyEnvironmentImpl.smali`

## Method to Patch

Find the method:
```smali
.method public getSynergyDirectorServerUrl(Lcom/ea/nimble/NimbleConfiguration;)Ljava/lang/String;
```

Or in some versions:
```smali
.method private getEnvironmentUrls()Ljava/lang/String;
```

## Patch Instructions

### Step 1: Locate the CUSTOMIZED Case

Search for this pattern in the method:
```smali
sget-object v[X], Lcom/ea/nimble/NimbleConfiguration;->CUSTOMIZED:Lcom/ea/nimble/NimbleConfiguration;
if-ne p1, v[X], :cond_[label]
```

Or look for:
```smali
const-string v[X], "NimbleCustomizedSynergyServerEndpointUrl"
```

### Step 2: Insert Community Server Check

**BEFORE** the existing `NimbleCustomizedSynergyServerEndpointUrl` code, insert:

```smali
    # === BEGIN COMMUNITY SERVER PATCH ===
    
    # Get application context
    invoke-static {}, Landroid/app/ActivityThread;->currentApplication()Landroid/app/Application;
    move-result-object v0
    
    # Check if context is null
    if-nez v0, :check_community_server
    goto :use_manifest_url
    
    :check_community_server
    # Create CommunityServerManager instance
    new-instance v1, Lcom/community/CommunityServerManager;
    invoke-direct {v1, v0}, Lcom/community/CommunityServerManager;-><init>(Landroid/content/Context;)V
    
    # Get active community server URL
    invoke-virtual {v1}, Lcom/community/CommunityServerManager;->getActiveServerUrl()Ljava/lang/String;
    move-result-object v2
    
    # Check if URL is not null
    if-nez v2, :check_empty
    goto :use_manifest_url
    
    :check_empty
    # Check if URL is not empty
    invoke-virtual {v2}, Ljava/lang/String;->isEmpty()Z
    move-result v3
    if-nez v3, :use_manifest_url
    
    # Return community server URL
    return-object v2
    
    :use_manifest_url
    # Fall through to existing manifest URL code
    
    # === END COMMUNITY SERVER PATCH ===
```

## Example: Complete Patched Method

```smali
.method public getSynergyDirectorServerUrl(Lcom/ea/nimble/NimbleConfiguration;)Ljava/lang/String;
    .registers 6
    .param p1, "config"    # Lcom/ea/nimble/NimbleConfiguration;

    # ... existing code ...
    
    # CUSTOMIZED case
    sget-object v1, Lcom/ea/nimble/NimbleConfiguration;->CUSTOMIZED:Lcom/ea/nimble/NimbleConfiguration;
    if-ne p1, v1, :cond_live
    
    # === OUR PATCH STARTS HERE ===
    invoke-static {}, Landroid/app/ActivityThread;->currentApplication()Landroid/app/Application;
    move-result-object v0
    
    if-nez v0, :check_community
    goto :use_manifest
    
    :check_community
    new-instance v1, Lcom/community/CommunityServerManager;
    invoke-direct {v1, v0}, Lcom/community/CommunityServerManager;-><init>(Landroid/content/Context;)V
    
    invoke-virtual {v1}, Lcom/community/CommunityServerManager;->getActiveServerUrl()Ljava/lang/String;
    move-result-object v2
    
    if-nez v2, :check_empty
    goto :use_manifest
    
    :check_empty
    invoke-virtual {v2}, Ljava/lang/String;->isEmpty()Z
    move-result v3
    if-nez v3, :use_manifest
    
    return-object v2
    # === OUR PATCH ENDS HERE ===
    
    :use_manifest
    # Original EA code continues...
    const-string v2, "NimbleCustomizedSynergyServerEndpointUrl"
    const-string v3, "https://syn-dir.sn.eamobile.com"
    invoke-static {v2, v3}, Lcom/ea/nimble/NimbleApplicationConfiguration;->getConfigValueAsString(Ljava/lang/String;Ljava/lang/String;)Ljava/lang/String;
    move-result-object v0
    
    return-object v0
    
    :cond_live
    # ... rest of method ...
.end method
```

## Automated Patching

The `RR3-Server-Browser-Installer.ps1` script should:

1. Decompile APK
2. Read `SynergyEnvironmentImpl.smali`
3. Find the CUSTOMIZED case
4. Insert patch code at the correct location
5. Save modified file
6. Rebuild APK

## Manual Patching

If the automated script fails:

1. Decompile APK: `apktool d realracing3.apk`
2. Open `smali/com/ea/nimble/SynergyEnvironmentImpl.smali` in text editor
3. Find `getSynergyDirectorServerUrl` method
4. Insert patch code as shown above
5. Rebuild: `apktool b realracing3`
6. Sign APK: `uber-apk-signer -a realracing3.apk`

## Testing

After patching:

```bash
# Install APK
adb install realracing3-patched.apk

# Set a community server URL
adb shell am start -n com.ea.games.r3_row/com.community.CommunityServersActivity

# Check if game uses it
adb logcat | grep -i synergy
```

You should see the game connecting to your community server URL instead of EA's!

## Troubleshooting

### Game crashes on start
- Check smali syntax is correct
- Verify register numbers don't conflict
- Ensure all labels are unique

### Still connecting to EA servers
- Patch may not have been applied
- Check active_server_url in SharedPreferences
- Verify CommunityServerManager.smali is present

### Can't find method
- Game version may have different method names
- Search for "getSynergyDirectorServerUrl" OR "getEnvironmentUrls"
- Look for "syn-dir.sn.eamobile.com" URL strings

## Important Notes

- Register numbers (v0, v1, etc.) may need adjustment based on existing code
- Label names (:use_manifest, :check_community) must be unique in the method
- This patch is compatible with RR3 versions 8.0+
- Always backup original APK before patching

**This patch is the KEY to community server support!** Once applied, the game will check SharedPreferences for a community server URL before falling back to EA's servers.
