Universal Anti-Split

📦 Universal Anti-Split — Advanced APK Merger Tool

Universal Anti-Split is a fast and modern Android utility designed to convert split APK packages into standalone APK files. It combines multiple application components into a single installable package, making it easier to manage and install apps distributed in split formats.

Supporting popular Android package formats, Universal Anti-Split processes application manifests, resources, and signatures directly on your device, without requiring an external conversion service.

⚡ Universal Split APK Conversion

Convert different Android package formats into a single standalone APK:

- XAPK — Bundled Android application packages. - APKM — APKMirror split packages. - APKS — Split APK bundles. - AAB — Android App Bundles.

The application merges the required components, helping create a standalone APK that can be installed independently of the original split package.

🚀 Dual Processing Engine

Universal Anti-Split uses two processing engines to balance performance and compatibility:

- Rust NDK Engine: A high-performance native engine designed for fast package processing. - Kotlin JVM Engine: A pure Kotlin fallback for alternative processing when needed.

This dual-engine architecture provides flexibility while handling different APK structures.

🛠️ Advanced APK Processing

The application performs several operations during conversion:

- Cleans and processes the binary Android manifest. - Merges application resources and "resources.arsc". - Re-signs the resulting APK directly on your device. - Supports Google APK Signature Schemes v1, v2, and v3. - Detects Google PairIP and Play Integrity protections and provides a Kill Signature option for supported cases. - Supports 16 KB page-size alignment for Android 15 and newer compatibility.

📥 Batch Conversion & Installation

Manage multiple packages through a convenient workflow:

- Batch merge several applications in one queue. - Install converted APKs directly through Android's Package Installer. - Share generated APK files with other apps. - Open the output folder to access converted packages. - View conversion history and package information.

⚠️ Important Disclaimer

Not every split application can be converted successfully. Some apps rely on device-specific components, additional data, server-side verification, or protection mechanisms that may prevent standalone operation. Removing or modifying signature-related protections does not guarantee that an application will work correctly or pass Play Integrity checks.
