Inside an Android App Bundle: Modules, Manifests and Configuration
An Android App Bundle organizes an application into modules rather than presenting the final device installation as one flat APK. Understanding the base.
APK & AAB analysis
AAB Analyzer
Inspect an Android App Bundle: selected base-manifest fields, manifest-bearing module names, bundle configuration presence and declared permissions, where decodable.
AAB Analyzer is part of APKLint, an online toolkit for inspecting Android APK files. Inspect an Android App Bundle: selected base-manifest fields, manifest-bearing module names, bundle configuration presence and declared permissions, where decodable. Upload an Android App Bundle (.aab) in your browser to view the relevant details; results reflect what the file itself exposes.

About AAB Analyzer
Inspect an Android App Bundle: selected base-manifest fields, manifest-bearing module names, bundle configuration presence and declared permissions, where decodable.
AAB Analyzer 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 AAB Analyzer checks
- Reads the bundle's protobuf base manifest (best-effort)
- Lists manifest-bearing modules and bundle configuration presence
- Reports package, version, and SDK levels where decodable
- Flags a target SDK below Google Play's per-form-factor target-API requirements (reviewed 22 September 2026)
Good to know: AAB manifest decoding is best-effort from protobuf; some fields may be partial. This tool accepts .aab only.
When to use AAB Analyzer
- Best for
- Inspecting selected protobuf base-manifest fields and module names in an Android App Bundle (.aab).
- Not the right tool for
- Not for .apk inputs (use APK Analyzer) and not a delivered-APK size estimate per device.
- What you get back
- Selected decoded base-manifest fields, manifest-bearing module names, bundle configuration presence and permission declarations. Full XML, module-type classification and configuration splits are not returned.
- How it differs from related APKLint tools
- Every other analyzer here takes an APK; this one understands the bundle format Google Play actually ingests.
- Limitations
- Bundle analysis is best-effort on the protobuf manifest; it does not run bundletool to generate per-device APKs.
How to use AAB Analyzer
- Choose your AAB file — Drop an .aab file onto the page, or click to select it from your device.
- Send securely — The file is uploaded over an encrypted connection to our analysis servers.
- Read your report — APKLint unpacks and inspects the package and lays out the results on screen.
- Your file is removed — It's deleted by an hourly cleanup job after analysis finishes.
