APK File Structure: What Each Folder Actually Contains
An APK is an installable Android package, not a folder of editable project source. Its ZIP container holds compiled code, compiled resources, a manifest.

APK Analyzer Online is part of APKLint’s apk & aab analysis toolkit — Unpack, inspect, and break down Android packages. It’s free to use and needs no account.
Your privacy is the default: files you upload are processed on our servers over an encrypted connection and permanently deleted by a scheduled hourly cleanup after analysis finishes, and never shared.
What APK Analyzer Online checks
- App label, package, versionName/versionCode
- Full permission list with dangerous ones flagged
- Activity / service / receiver / provider counts
- DEX class & method counts, signing details, and a size breakdown with largest files
Good to know: This is the broad overview. For a single focus, use the size, signing, or release-readiness tools.
When to use APK Analyzer Online
- Best for
- Reviewing package identity, aggregate DEX counts, manifest findings, native ABI names and an uncompressed size breakdown in one report.
- Not the right tool for
- Overkill if you only need the signing certificate (use APK Signature Checker) or only the size breakdown (use APK Size Analyzer).
- What you get back
- Aggregate class/method counts within scan limits, component counts, permission declarations, min/target SDK, size categories, selected largest files and signing metadata. Per-DEX field counts, compile SDK and a full resource inventory are not provided.
- How it differs from related APKLint tools
- APK Checker emphasizes release-readiness findings, APK Scanner emphasizes manifest/permission risk notes, and APK Analyzer combines more structural summaries. It is not a replacement for Android Studio's full analyzer.
- Limitations
- It describes structure and metadata; it is not a malware verdict or a security audit. For those use the Malware Scanner or Security Scanner.
