APK Analyzer

Upload an .apk to inspect its ZIP layout, count DEX files, detect native .so libraries, compute a SHA-256 fingerprint, and surface heuristic hints from binary AndroidManifest.xml strings — all locally in your browser.

What is an online APK analyzer?

An APK analyzer is a utility that treats an Android application package as what it technically is: a ZIP archive containing compiled code, resources, signing metadata, and the compiled AndroidManifest.xml binary. DroidXP’s tool is designed for developers, QA testers, and power users who need a fast sanity check of package contents without installing desktop suites or uploading files to unknown servers. Because parsing happens in your browser, you keep control of the artifact you are inspecting — an important trust signal when working with pre-release or proprietary builds.

What does this APK analyzer do?

The analyzer loads your .apk with JSZip, walks every entry, and prints a structured report. You get a SHA-256 hash of the entire file (useful for integrity checks), a count of DEX files (multi-dex apps show multiple classes*.dex entries), and detection of native .so libraries under lib/. The tool highlights notable paths such as resources.arsc, META-INF signing material, assets/, and Kotlin metadata folders when present. For AndroidManifest.xml, the on-disk format is typically binary AXML, not plain XML; this utility scans printable strings for common patterns (for example package and version hints). Full AXML decoding is a heavier problem — here we optimize for speed and transparency while still delivering actionable signal.

  • Full archive listing with per-entry sizes when available from the ZIP directory
  • Summary stats: entry count, DEX count, compressed download size, native library presence
  • Heuristic metadata hints extracted from manifest byte strings (when patterns appear)
  • Cryptographic fingerprint via Web Crypto SHA-256

How to use the APK Analyzer

  1. Step 1: Click the drop zone or drag an .apk from your build output or device backup.
  2. Step 2: Wait a moment while the archive is parsed — large apps may take longer on low-memory devices.
  3. Step 3: Read the summary at the top of the report, then scan “Notable paths” for manifest, resources, and ABI splits.
  4. Step 4: Use Copy report to paste findings into bug tickets, CI logs, or team chat.

Benefits of using this tool

  • Release confidence: Quickly verify that expected DEX and native artifacts exist before shipping to testers.
  • Security review: Pair the SHA-256 fingerprint with your build pipeline outputs to catch mismatches early.
  • Education: See how real APKs are structured — valuable for students and indie developers learning Android packaging.
  • 100% Free & Private: Your APK is not uploaded to DroidXP servers; analysis uses your CPU and memory only.

Frequently Asked Questions

Is this APK analyzer free to use?

Yes. DroidXP provides this analyzer at no charge. We may show display ads on the page after approval, but the tool itself does not require payment or an account.

Does the tool upload my APK to a server?

No. The file is read with the browser’s FileReader pipeline into memory and processed with JavaScript. Always review your organization’s policies before analyzing highly sensitive builds on any network-connected machine.

Why don’t I see plain XML for AndroidManifest.xml?

Packaged manifests are usually compiled to binary XML for size and speed. Fully decoding AXML to a tree requires specialized parsers; this tool focuses on fast structural inspection and string heuristics instead.

Can I use this for split APKs and App Bundles?

You can analyze any file with an .apk extension, including split APK parts. Android App Bundles (.aab) are a different format — use bundletool outputs or convert to universal APKs before inspection here.

Does it work on mobile browsers?

Modern mobile Chromium and Safari generally support the required APIs, but very large APKs may hit memory limits. For huge artifacts, prefer desktop Chrome or Edge.
