Running the command $apktool d app.apk$ extracts all resources, decodes the resources.arsc into readable .xml files, and places them in the res/ directory.

(most common)
| Tool | Primary Purpose | Key Feature | | :--- | :--- | :--- | | | Rebuilding APKs after modifications | The industry standard, can decode a majority of resources to nearly original form, then rebuild them. | | APKEditor | Resource modification | Uses ARSCLib to enable editing without needing the Android Asset Packaging Tool (AAPT). | | Jadx | DEX to Java decompiler | Decompiles Java code and can also decode resources.arsc and other resources, offering a high-level view. | | Androguard | Reverse engineering in Python | A powerful suite for analysis; its androguard arsc command-line tool efficiently decodes resources.arsc files. | | AXMLEditor | Binary editing | A specialized Java tool for directly modifying binary ARSC files, useful when standard decompilation and rebuilding are problematic. | | abxml | Rust library for parsing | A Rust crate for parsing APKs, including resources.arsc and binary XML files, useful for building custom tools. | | 010 Editor | Advanced binary analysis | A generic hex editor with a powerful template system; its AndroidResource.bt template can parse .arsc and AXML files. | | MT Manager | All-in-one tool | A popular Android app that offers a visual ARSC editor, allowing direct modifications on your phone. |
Reverse engineers, developers, and security analysts rely on ARSC decompilers for several critical tasks:
: The primary function is extracting compiled resources (like strings, localized text, and layout configurations) into a readable format for inspection or modification. Automatic ZIP Packaging
Decodes color hex codes, dimension values (dp, sp), and theme styles.
When you load an APK into Jadx, it automatically parses resources.arsc and displays the resources in a clean, navigable tree structure inside the GUI. Best for: Quick code audits and visual security analysis. 3. Androguard
You might ask: Doesn't apktool already decode resources.arsc?
file is a binary index that contains application resources such as strings, layouts, and style references. Key Features of an ARSC Decompiler
A lot of new reverse engineers get confused when they try to open resources.arsc in a standard text editor and see garbage. That’s because Android converts resource XMLs into a highly optimized binary format (proto-XML or binary XML) and compiles the lookup tables into ARSC.
Decompiling for personal use, educational purposes, or interoperability is generally accepted in many jurisdictions. However, redistributing modified versions of someone else's app or using decompilers to bypass security features can violate Terms of Service or copyright laws. Always check the legalities if you plan to share your work.
Security analysts use ARSC decompilers to inspect an application's hardcoded strings, API endpoints, hidden configurations, or keys that might have been mistakenly left in the resource files.
Several open-source and commercial tools excel at decompiling Android resource tables.
(Python library)
Instructions on which resources to load based on screen density (hdpi, xhdpi), orientation, or API level.
Because resources hold vital clues about an application, developers and commercial packers often use resource obfuscation tools (such as ) to thwart ARSC decompilers. How Resource Obfuscation Works:
