Check an APK File: Identity, Integrity and Risk Are Different Questions
To check an APK file properly, separate three questions: what package is this, has its signed content been modified, and does its behavior create.

What Android App Scanner checks
- Security-first read of the manifest
- Dangerous permissions and exposed components
- Signing scheme weaknesses (e.g. v1-only)
- Cleartext and debuggable flags
Good to know: Static, manifest-driven security signals — not a substitute for dynamic testing.
When to use Android App Scanner
- Best for
- A security-leaning structural scan of an uploaded APK: it reads the manifest with risk in mind, flagging debuggable builds, exported components, and cleartext settings alongside the basics.
- Not the right tool for
- Not the place for a size audit or a pure metadata dump; use APK Size Analyzer or APK Analyzer for those.
- What you get back
- A risk-oriented summary: permissions of note, exported surfaces, debuggable/backup flags, and signing, with the riskier findings called out.
- How it differs from related APKLint tools
- Compared with APK Scanner (contents) and APK Analyzer (structure), Android App Scanner is tilted toward 'what here could be a security problem'.
- Limitations
- It is a static manifest-level scan, not a dynamic test or a guaranteed malware verdict.
