Arsc Decompiler Link

Modern obfuscators like ProGuard can rename resources (e.g., ic_launcher → a). The ARSC decompiler still shows the obfuscated name, but the ID mapping remains correct.

Google designed resources.arsc to be memory-mapped directly by Android's AssetManager. This demands a compact, binary format with no XML tags. However, this binary nature also makes it a favorite target for resource obfuscation. Tools like ProGuard (R8) can rename res/layout to res/a and button_click to c, turning the ARSC file into a near-impenetrable mapping of meaningless identifiers.

An ARSC decompiler reverses this binary structure into human-readable forms like ARSC (plain text), XML, or JSON.

Androguard’s ARSC module is powerful for scripting. arsc decompiler

Example snippet:

from androguard.core.androguard import APK
a = APK("app.apk")
for pkg in a.get_packages():
    print(pkg.get_name())
    for res in pkg.get_resources():
        print(res.get_key(), res.get_value())

Best for: Security researchers writing automated scanners.

resources.arsc does not contain layout XML source; it only holds IDs referencing compiled binary XML files (in res/layout/). Don’t expect to recover original XML formatting from ARSC alone. Modern obfuscators like ProGuard can rename resources (e

Though primarily an APK decompiler, Apktool contains an excellent ARSC decompiler.

Command:

apktool d app.apk

This produces a res/ folder with decoded values/strings.xml and a public.xml file. Androguard’s ARSC module is powerful for scripting

Why use it: It handles complex configurations, framework resources, and even reconstructs Android 14’s new resource features.

Limitation: Can be slow on huge APKs (500MB+).
