# 🔧 Smali Patches for RR3 Server Browser
|
||||
|
||||
This directory contains the Android smali bytecode files that enable the in-game server browser.
|
||||
|
||||
## 📁 Files
|
||||
|
||||
### Core Bridge Code
|
||||
|
||||
**`CommunityServerManager.smali`**
|
||||
- JavaScript ↔ Android bridge
|
||||
- SharedPreferences management
|
||||
- Server CRUD operations
|
||||
- Annotated with `@JavascriptInterface`
|
||||
|
||||
**`CommunityServersActivity.smali`**
|
||||
- WebView host for server list UI
|
||||
- Loads `community_servers_list.html`
|
||||
- Manages lifecycle
|
||||
|
||||
**`ServerEditActivity.smali`**
|
||||
- WebView host for server edit form
|
||||
- Loads `community_server_edit.html`
|
||||
- Add/edit server UI
|
||||
|
||||
### Game Integration
|
||||
|
||||
**`SynergyEnvironmentImpl.patch`**
|
||||
- Modifies game's network code
|
||||
- Checks SharedPreferences for community server URL
|
||||
- Falls back to EA servers if none set
|
||||
|
||||
## 🔌 How It Works
|
||||
|
||||
```
|
||||
┌─────────────────────────────────────────────────────────────┐
|
||||
│ Game Flow │
|
||||
└─────────────────────────────────────────────────────────────┘
|
||||
|
||||
1. User opens Server Browser
|
||||
└─> CommunityServersActivity launches
|
||||
└─> Loads community_servers_list.html
|
||||
└─> JavaScript calls AndroidInterface methods
|
||||
└─> CommunityServerManager (smali) handles calls
|
||||
└─> Reads/writes SharedPreferences
|
||||
|
||||
2. User adds server and taps "Connect"
|
||||
└─> JavaScript: AndroidInterface.setActiveServer(id)
|
||||
└─> Smali: Saves active_server_url to SharedPreferences
|
||||
|
||||
3. User restarts game
|
||||
└─> Game calls getSynergyDirectorServerUrl()
|
||||
└─> SynergyEnvironmentImpl (PATCHED) checks:
|
||||
├─> Community server URL in SharedPreferences?
|
||||
│ ├─> YES: Return community URL ✅
|
||||
│ └─> NO: Return EA server URL (fallback)
|
||||
```
|
||||
|
||||
## 🎯 Installation
|
||||
|
||||
### Automatic (Recommended)
|
||||
|
||||
Use the installer script:
|
||||
|
||||
```powershell
|
||||
cd E:\rr3\rr3-apk
|
||||
.\RR3-Server-Browser-Installer.ps1 -ApkPath "realracing3.apk"
|
||||
```
|
||||
|
||||
The script will:
|
||||
1. Decompile APK with apktool
|
||||
2. Copy smali files to `smali/com/community/`
|
||||
3. Apply SynergyEnvironmentImpl patch
|
||||
4. Update AndroidManifest.xml
|
||||
5. Rebuild and sign APK
|
||||
|
||||
### Manual
|
||||
|
||||
If you prefer manual installation:
|
||||
|
||||
1. **Decompile APK**
|
||||
```bash
|
||||
apktool d realracing3.apk -o rr3-decompiled
|
||||
```
|
||||
|
||||
2. **Create directory structure**
|
||||
```bash
|
||||
mkdir -p rr3-decompiled/smali/com/community
|
||||
```
|
||||
|
||||
3. **Copy smali files**
|
||||
```bash
|
||||
cp CommunityServerManager.smali rr3-decompiled/smali/com/community/
|
||||
cp CommunityServersActivity.smali rr3-decompiled/smali/com/community/
|
||||
cp ServerEditActivity.smali rr3-decompiled/smali/com/community/
|
||||
```
|
||||
|
||||
4. **Apply patch**
|
||||
- Open `rr3-decompiled/smali/com/ea/nimble/SynergyEnvironmentImpl.smali`
|
||||
- Find `getSynergyDirectorServerUrl` method
|
||||
- Insert patch code from `SynergyEnvironmentImpl.patch`
|
||||
- Save file
|
||||
|
||||
5. **Update AndroidManifest.xml**
|
||||
```xml
|
||||
<activity
|
||||
android:name="com.community.CommunityServersActivity"
|
||||
android:label="Community Servers"
|
||||
android:theme="@android:style/Theme.Black.NoTitleBar.Fullscreen"
|
||||
android:exported="true"/>
|
||||
|
||||
<activity
|
||||
android:name="com.community.ServerEditActivity"
|
||||
android:label="Server Settings"
|
||||
android:theme="@android:style/Theme.Black.NoTitleBar.Fullscreen"
|
||||
android:exported="false"/>
|
||||
```
|
||||
|
||||
6. **Rebuild APK**
|
||||
```bash
|
||||
apktool b rr3-decompiled -o realracing3-modded.apk
|
||||
```
|
||||
|
||||
7. **Sign APK**
|
||||
```bash
|
||||
uber-apk-signer -a realracing3-modded.apk
|
||||
```
|
||||
|
||||
## 🧪 Testing
|
||||
|
||||
### 1. Install Modified APK
|
||||
|
||||
```bash
|
||||
adb install realracing3-community.apk
|
||||
```
|
||||
|
||||
### 2. Launch Server Browser
|
||||
|
||||
```bash
|
||||
adb shell am start -n com.ea.games.r3_row/com.community.CommunityServersActivity
|
||||
```
|
||||
|
||||
Expected: Beautiful server browser UI appears
|
||||
|
||||
### 3. Check JavaScript Bridge
|
||||
|
||||
Open Chrome DevTools:
|
||||
1. In Android device: Settings → Developer Options → Enable USB Debugging
|
||||
2. On PC: Open Chrome → `chrome://inspect`
|
||||
3. Find WebView → Inspect
|
||||
4. In console, type:
|
||||
```javascript
|
||||
AndroidInterface.getServers()
|
||||
AndroidInterface.showToast("Hello from JavaScript!")
|
||||
```
|
||||
|
||||
### 4. Test SharedPreferences
|
||||
|
||||
```bash
|
||||
# Check if data is being saved
|
||||
adb shell run-as com.ea.games.r3_row cat shared_prefs/com.ea.games.r3_row_preferences.xml
|
||||
|
||||
# Look for:
|
||||
# <string name="community_servers">[...]</string>
|
||||
# <string name="active_server_url">http://...</string>
|
||||
```
|
||||
|
||||
### 5. Verify Game Uses Community Server
|
||||
|
||||
```bash
|
||||
# Start game and watch logs
|
||||
adb logcat | grep -i -E "(synergy|director|community)"
|
||||
|
||||
# You should see requests to your community server URL instead of:
|
||||
# syn-dir.sn.eamobile.com
|
||||
```
|
||||
|
||||
## 📝 Smali Reference
|
||||
|
||||
### JavascriptInterface Methods
|
||||
|
||||
These methods are callable from JavaScript:
|
||||
|
||||
```javascript
|
||||
AndroidInterface.getServers() // Returns: JSON string "[]"
|
||||
AndroidInterface.getActiveServerId() // Returns: string ""
|
||||
AndroidInterface.addServer(jsonString) // Saves server
|
||||
AndroidInterface.setActiveServer(id) // Activates server
|
||||
AndroidInterface.deleteServer(id) // Removes server
|
||||
AndroidInterface.showToast(message) // Shows Android toast
|
||||
AndroidInterface.getEditingServerId() // For edit mode
|
||||
// ... see CommunityServerManager.smali for all methods
|
||||
```
|
||||
|
||||
### SharedPreferences Keys
|
||||
|
||||
```
|
||||
com.ea.games.r3_row_preferences:
|
||||
├─ community_servers: "[{...}]" # JSON array of server objects
|
||||
├─ active_server_id: "uuid-1234" # Currently active server
|
||||
├─ active_server_url: "http://..." # URL game will connect to
|
||||
└─ editing_server_id: "uuid-5678" # Server being edited
|
||||
```
|
||||
|
||||
## 🐛 Troubleshooting
|
||||
|
||||
### Server Browser Won't Open
|
||||
|
||||
```bash
|
||||
# Check if activities are registered
|
||||
adb shell dumpsys package com.ea.games.r3_row | grep -A 20 activity
|
||||
|
||||
# Should show:
|
||||
# com.community.CommunityServersActivity
|
||||
# com.community.ServerEditActivity
|
||||
```
|
||||
|
||||
**Fix**: Activities not in AndroidManifest.xml - re-run installer
|
||||
|
||||
### JavaScript Errors
|
||||
|
||||
```bash
|
||||
# Enable WebView debugging in smali
|
||||
# Add to onCreate() in CommunityServersActivity:
|
||||
|
||||
invoke-static {}, Landroid/webkit/WebView;->setWebContentsDebuggingEnabled(Z)V
|
||||
```
|
||||
|
||||
Then inspect with Chrome DevTools
|
||||
|
||||
### Game Ignores Community Server
|
||||
|
||||
**Symptom**: Still connects to EA servers
|
||||
|
||||
**Check**:
|
||||
```bash
|
||||
# Is active_server_url set?
|
||||
adb shell run-as com.ea.games.r3_row cat shared_prefs/com.ea.games.r3_row_preferences.xml | grep active_server_url
|
||||
```
|
||||
|
||||
**Fix**:
|
||||
- Verify SynergyEnvironmentImpl.patch was applied
|
||||
- Check smali syntax for errors
|
||||
- Rebuild APK with correct patch
|
||||
|
||||
### Crashes on Launch
|
||||
|
||||
**Common causes**:
|
||||
- Smali syntax errors (mismatched registers, labels)
|
||||
- Missing CommunityServerManager.smali
|
||||
- Wrong class path (must be `com/community/`)
|
||||
|
||||
**Debug**:
|
||||
```bash
|
||||
adb logcat | grep -i -E "(fatal|exception)"
|
||||
```
|
||||
|
||||
Look for ClassNotFoundException or VerifyError

||||

### Understanding Smali
|
||||
|
||||
- **Registers**: `v0`, `v1` are local variables
|
||||
- **Parameters**: `p0` is `this`, `p1` is first parameter
|
||||
- **Types**:
|
||||
- `Ljava/lang/String;` = String
|
||||
- `Landroid/content/Context;` = Context
|
||||
- `Z` = boolean
|
||||
- `I` = int
|
||||
|
||||
### Useful Commands
|
||||
|
||||
```bash
|
||||
# Decompile single class
|
||||
baksmali d classes.dex -o output/
|
||||
|
||||
# Compile single class
|
||||
smali a output/ -o classes.dex
|
||||
|
||||
# Disassemble DEX
|
||||
dexdump -d classes.dex
|
||||
|
||||
# Check APK signature
|
||||
jarsigner -verify -verbose realracing3.apk
|
||||
```
