What This Project Does

Takes the official GameHub APK (114MB) and converts it into a privacy-focused Lite version (51MB):

• Removes tracking: 11,838 telemetry/analytics files deleted (Firebase, Google Analytics, Umeng, JPush, etc.)
• Optimizes size: PNG images converted to WebP format, unused libraries removed
• Bypasses authentication: No login required, works offline
• Removes permissions: 31 invasive permissions eliminated (location, mic, camera, contacts, etc.)
• Redirects network: All API calls go to self-hostable Cloudflare Workers
• Adds features: External launcher support for Daijisho, Launchbox, etc.

Result: 114MB bloated APK → 51MB clean APK with zero tracking

Auto-Patcher

The automated patcher applies all modifications to any GameHub APK version.

Requirements

macOS:

brew install apktool
brew install openjdk@17
brew install --cask android-commandlinetools

Linux:

sudo apt-get install apktool
sudo apt-get install openjdk-17-jdk
# Install Android SDK command-line tools from https://developer.android.com/studio

Running the Patcher

1. Download the official GameHub APK
2. Place it in this folder
3. Run:

./autopatcher.sh GameHub-5.1.0.apk

The script will:

• Decompile the APK
• Remove 11,838 telemetry files
• Copy 2,851 optimized WebP images
• Apply 201 code patches
• Rebuild and sign the APK

Output: GameHub-Lite-20251017-003625-signed.apk (takes 2-3 minutes)

Install It

adb install -r GameHub-Lite-*.apk

Or drag the APK to your Android device and install normally.

Required Repositories

This project requires the following Cloudflare Worker repositories for full functionality:

1. gamehub-worker (https://github.com/gamehublite/gamehub-worker) - Main API proxy worker

   • Handles all GameHub API requests
   • Token replacement and signature regeneration
   • Privacy features (IP protection, fingerprint sanitization)

2. gamehub_api (https://github.com/gamehublite/gamehub_api) - Static API resources

   • Component manifests (Wine, Proton, DXVK, VKD3D)
   • Game configurations and profiles
   • Served via GitHub raw URLs

3. gamehub-news (https://github.com/gamehublite/gamehub-news) - News aggregator worker

   • Aggregates gaming news from RSS feeds
   • Tracks GitHub releases for emulation projects
   • Custom HTML styling for mobile

4. gamehub-login-token-grabber (https://github.com/gamehublite/gamehub-login-token-grabber) - Token refresher worker

   • Automated token refresh every 4 hours
   • OTP-based authentication via Mail.tm
   • Stores fresh tokens in KV storage

Note: You can self-host all Workers for complete privacy. Right now I'm using free Cloudflare Workers. Don't misuse the project.

External Launcher Support

Launch Steam games directly from other Android frontends:

am start -n gamehub.lite/com.xj.landscape.launcher.ui.gamedetail.GameDetailActivity \
  -a gamehub.lite.LAUNCH_GAME \
  --es steamAppId "292030" \
  --ez autoStartGame true

This lets you use GameHub as a backend for:

• Daijisho
• Launchbox
• RetroArch
• Any Android launcher that supports custom intents

Troubleshooting

"apktool not found"

• Install it: brew install apktool (macOS) or sudo apt-get install apktool (Linux)

"Java not found"

• Install JDK: brew install openjdk@17 or download from Oracle

"zipalign not found"

• Install Android SDK build-tools
• Script will auto-detect if installed via Homebrew

Some patches failed

• That's normal. GameHub updates sometimes change code layout
• The script still applies all successful patches (usually 196+ out of 201)
• Failed patches are usually minor and could be manually fixable

App crashes on launch

• Something went wrong, check logcat
• Try: adb uninstall gamehub.lite && adb install -r GameHub-Lite-*.apk

Customization

Add Your Own Images

Put PNG/WebP files in lite_resources/res/drawable-xxhdpi/ and they'll be included in all patched APKs.

Example: We added wine_game_loading.jpg (the blue splash screen when games launch).

Change the Signing Key

Script will auto-generate a new keystore. Default password is password123.

Modify Patches

To add new patches:

1. Make your changes to a decompiled APK
2. Generate diff: diff -u original.xml modified.xml > patches/mychange.diff
3. The autopatcher will automatically include it
