Convert XAPK to APK for Android Reverse Engineering

What is XAPK?

XAPK is a file format used to distribute Android applications that include:

• The main APK file
• Additional OBB / data resources

It is commonly used by third-party app stores to bundle large applications.

However, most reverse engineering tools (APKTool, JADX, Frida, etc.) only work with standard APK files.

Why Convert XAPK to APK?

In Android reverse engineering, converting XAPK to APK is usually the first step in order to:

• Decompile the app source code
• Analyze AndroidManifest.xml
• Inspect resources (layouts, strings, assets)
• Perform static or dynamic analysis

Without converting, XAPK files cannot be directly processed by most Android analysis tools.

Tools to Convert XAPK to APK

There are two main approaches:

1. Manual Method

• Rename .xapk to .zip
• Extract files
• Merge APK and OBB manually

This method is slow and error-prone.

2. Online / Automated Tools (Recommended)

A faster approach is using online tools like:

👉 https://xapktool.com

xapktool.com allows you to:

• Upload XAPK
• Automatically extract and merge files
• Download a clean APK file directly from browser

No installation required.

Reverse Engineering Workflow

A typical Android reverse engineering pipeline:

1. Convert XAPK → APK (using xapktool.com)
2. Decompile:
   • APKTool (resources)
   • JADX (Java/Kotlin source)
3. Dynamic analysis:
   • Frida
   • Objection
4. Rebuild & resign APK if needed
