## APKLint: Android App Analysis in Your Browser
APKLint is a free Android development toolkit from Takenick Innovation. It brings together 61 tools and guides for APK and AAB inspection, manifest checks, code review, security risk analysis, and Google Play preparation. No account or local software installation is required.
### What you can do
* **Inspect APKs:** Review package identity, versions, SDK levels, permissions, components, signing metadata, and size breakdowns.
* **Explore app bundles:** Examine supported AAB manifest fields, module information, and declared permissions.
* **Decode and decompile:** Use hosted Apktool and JADX workflows to inspect resources, smali, and recovered Java-like source.
* **Review security indicators:** Check manifest settings, exposed components, suspicious patterns, SDKs, and malware indicators.
* **Check source and configuration:** Analyze pasted Java, Kotlin, AndroidManifest XML, Gradle configuration, and crash traces with focused checks.
* **Prepare for release:** Use release checklists, privacy-policy drafting tools, Data Safety guidance, and Google Play listing helpers.
### Built for practical checks
APKLint is designed for Android developers, independent app publishers, QA testers, and learners who need an accessible way to inspect a build or investigate a specific issue. Tools are organized by task, with no third-party ad banners on their pages.
### How data is handled
Interactive analysis runs on APKLint's servers over HTTPS. Uploaded packages and generated results are removed by the next hourly cleanup after analysis finishes. Pasted text is processed for the request without being written to file or object storage. Reference checklists run in the browser.
Results support investigation and release preparation; they do not guarantee app safety, regulatory compliance, or Google Play approval.
