Universal Installer

Universal Installer is a modern Android package manager that handles what the default installer can't.

Install APK, APK+, APKS, XAPK, APKM (with split APKs and OBB files), download packages from URLs, manage installed apps, and silent-install via Shizuku — all in one Material 3 app. Now with Android TV support.

• Expressive UI — Beautiful, bouncy spring animations (inspired by InstallerX-Revived) that make the dialog card "living" and responsive.
• Brand Identity — Sleek default Orange theme for a premium, high-contrast look (Dynamic Color still available as an option).

• Multi-format — .apk, .apk+, .apks, .xapk, .apkm with split APK handling (via Ackpine)
• Merge split APKs — Group multiple individual .apk files (e.g. from a manual split extraction) into a single installation session. Perfect for installing apps served as a collection of separate splits.
• Modern Android Support — Fully compatible with Android 14, 15, 16, and ready for Android 17. Fixes common parsing errors (e.g. aconfig_flags.pb) found on newer system versions.
• Package preview — App name, icon, version, package, size, min/target SDK, supported ABIs, languages, permissions, OBB count, split count — shown in a bottom sheet before you commit
• Three local pick modes — Find automatic (scans device storage), Browse packages (APK/XAPK/APKS/APKM only), Browse all files
• Remote download — Paste a URL, download package directly. Files land in /sdcard/Download/UniversalInstaller/ with their Content-Disposition name so they're easy to re-find in any file manager
• Download history — Every download is logged; re-install later, copy the source URL, or delete from the dedicated history screen
• Intent handling — Open APK/XAPK files from Chrome downloads, Gmail attachments, Telegram, or any file manager — even when the URL has no extension

• Bundle-embedded OBBs — XAPK/APKM/APKS archives containing .obb files are auto-detected and copied to Android/obb/<package>/ after the APK installs
• Standalone attach — Pick a base APK, then attach one or more .obb files via the preview sheet; they're installed alongside
• Runs in a foreground worker — OBB copy survives app closure, with progress on the notification shade
• Three write strategies — Falls back in order based on what the device permits:
  1. Direct I/O (pre-Android 11)
  2. Shizuku (shell UID can write to any app's OBB dir on modern Android)
  3. SAF tree grant (user grants access to Android/obb/<pkg>/ once per package; reused on subsequent installs)

• VirusTotal integration — Auto SHA-256 hash lookup on every picked file; if VirusTotal doesn't know the file yet, optionally upload it for a full multi-engine scan (supports files up to 650 MB via VirusTotal's large-file endpoint)
• Clear verdict — See engine counts (malicious / suspicious / harmless / undetected) before you install

When Root access or Shizuku is enabled, unlocks:

• Installer Profiles — Save and reuse custom install configurations (installer package spoofing, privileged flags, targeted users) per app or globally.
• Silent install / uninstall — No system confirmation prompt
• Replace existing, Allow downgrade, Grant all requested permissions, Allow test packages, Bypass low target SDK block, Install for all users
• Set install source — Spoof the installer package name (Google Play, Aurora, F-Droid, Amazon, Samsung, Huawei, Xiaomi presets, or custom) so apps with "installed from Play Store" checks accept your sideload

• Send to TV — Quickly transfer and install packages on your Android TV by scanning a QR code.
• Built-in HTTP server — Share and manage your packages across a local Wi-Fi network from any browser.
• Web dashboard — Download APKs straight to your PC or upload new packages directly to your phone.
• Live tracking — Real-time progress updates visible inside the app as files transfer.
• PIN security — Set an optional 4–8 digit PIN code to restrict local access to your shared folder.

• Full app list — Browse user apps (system apps optional)
• Rich metadata — App name, package, version, APK size, first install date, last used time
• Sort — By Name / Size / Installed date / Last used — each with ascending/descending toggle
• Batch select — Long-press to enter selection mode, uninstall many at once
• Filter sheet — Tap FAB for sort/filter options; long-press FAB to scroll to top
• Usage access hint — "Last used" sort prompts user to grant the Usage Access permission only when needed
• Uninstall logs — Separate log screen for every uninstall attempt (success / failure with reason)

• Storage card on Install screen — At-a-glance internal storage usage (free / total, color-coded warning at 75% / 90%)
• Install history — Every install attempt logged with app name, package, version, success/failure, and error reason

• Material 3 — Orange brand theme (default) + Dynamic color + Light / Dark / System theme
• Multi-language — Arabic, German, Greek, English, Spanish, French, Hindi, Indonesian, Italian, Japanese, Korean, Portuguese (BR), Russian, Turkish, Ukrainian, Vietnamese, Chinese
• Progress notifications — Download, install, and OBB copy all surface their progress in the notification shade

• Kotlin + Jetpack Compose — UI
• Ackpine — Package install/uninstall with split APK, Shizuku, and libsu plugins
• Shizuku — Privileged operations via ADB/root
• Ktor — HTTP client for VirusTotal and remote downloads
• WorkManager — Foreground worker for OBB copy (survives app process death)
• Room — Local DB for install / uninstall / download history
• Koin — Dependency injection
• DataStore — Preferences storage
• Coil 3 — App icon loading

• Android Studio
• JDK 17+ (required by AGP 8.11)
• Android SDK 36

The project is a multi-module Gradle build:

A single distribution ships Shizuku, Root (libsu), and the default system installer together — the old store / full product flavors were removed.

1. Clone the repository:

   git clone https://github.com/pass-with-high-score/universal-installer.git
   cd universal-installer

2. Open the project in Android Studio
3. Pick the app (phone) or tv run configuration, sync Gradle, and run on a device (an emulator works for most features except Shizuku-backed install)

# Phone app
./gradlew :app:assembleDebug
./gradlew :app:assembleRelease

# Android TV app
./gradlew :tv:assembleDebug
./gradlew :tv:assembleRelease

# Release App Bundle (phone + TV)
./gradlew assembleBundleRelease

# Everything at once
./gradlew assembleDebug

# Install dependencies
bundle install

# Build debug APK
bundle exec fastlane build_debug

# Build release APK
bundle exec fastlane build_release

# Deploy beta to Firebase App Distribution
bundle exec fastlane beta

# Deploy to Play Store internal track
bundle exec fastlane internal

# Bump version code
bundle exec fastlane bump_version

# Bump version code + name
bundle exec fastlane bump_version version_name:"2.0"

1. Install Shizuku on your device
2. Start the Shizuku service via ADB (or via the Shizuku app if rooted)
3. Open Universal Installer → Settings → Installation → Shizuku Backend → grant permission when prompted
4. Optional: enable Set install source to pick the installer package name apps will see

1. Get a free API key at virustotal.com/gui/my-apikey
2. Settings → Security → VirusTotal API Key → paste key
3. Every picked APK is hashed and looked up automatically; unknown files can be uploaded on demand from the preview sheet

• Android 11+: grant All files access when prompted (used for Find automatic device scan and for the direct-write OBB path). If you decline, OBB copy falls back to Shizuku or a per-package SAF tree grant
• Pre-Android 11: falls back to legacy READ/WRITE_EXTERNAL_STORAGE
• Usage access (optional, Uninstall screen only): grant when you tap the "Last used" sort option — enables sorting and date metadata per row
