Even when you do everything right, you may encounter errors. Here is how to fix them.

Given an Android APK, extract all configuration constants (strings, booleans, integers) that influence runtime behavior, with special emphasis on network endpoints and conditional flags.

APK2GetCon fills this gap by providing a dedicated configuration contract extractor.

If you don't know the path to the APK you want to check (APKs are usually installed in /data/app/ or /data/app-private/ on a device), you can find it by listing installed packages: apk2getcon

pm list packages

Then, for a specific package:

pm path package.name

Replace package.name with the actual name of the package.

# Pseudo-code for APK2GetCon core logic
class APK2GetCon:
    def extract_config(apk_path):
        config = {}
        manifest = parse_manifest(apk_path)
        config['package'] = manifest.package
        config['version'] = manifest.version_code

    resources = decode_resources(apk_path)
    config['strings'] = filter_config_strings(resources)
bytecode = decompile_to_smali(apk_path)
    config['constants'] = find_constants(bytecode, pattern_list)
return json.dumps(config, indent=2)

Pattern list (YAML-based):

- pattern: "https?://[a-zA-Z0-9./_-]+"
  type: URL
- pattern: "FEATURE_[A-Z_]+"
  type: FLAG
- pattern: "TIMEOUT_MS = [0-9]+"
  type: TIMEOUT

At its core, APK2GetCon is the bridge between the compiled code that runs on your phone and the readable logic that humans write. When a developer builds an app, the source code is compiled into DEX files (Dalvik Executable) and bundled with resources and a manifest file. The APK2GetCon process reverses this, allowing the user to: Even when you do everything right, you may encounter errors

When compared to industry leaders in the APK space, Apk2GetCon falls short.
