Packet Capture for Android

At-a-glance summary

Packet Capture is an Android app that sniffs network traffic and can decrypt SSL sessions. It’s particularly handy for debugging network behaviour while you’re building apps. The tool is straightforward to operate and does not require root privileges, which makes it accessible for most developers.

Primary functionalities

• Record and save network packets for later inspection
• Decrypt SSL/TLS traffic using a man-in-the-middle method
• Display captured data in both hexadecimal and plain-text views
• Run without root access, relying on user-level methods
• Simple, easy-to-learn interface for quick debugging sessions
• Still somewhat basic in features compared with more mature tools

Practical notes for use

The app lets you capture and examine traffic so you can trace requests, responses, headers and payloads. Being able to view data in hex or text helps when you need low-level or readable representations. Its SSL decryption makes it possible to analyze encrypted flows during development, which is why many developers find it valuable despite the app’s limited extras.

If you see a lock-screen PIN prompt after uninstalling

After removing Packet Capture, Android may still prompt for a PIN because a user credential (certificate) was installed. To clear this and restore the previous lock-screen behavior, open your device Settings → Security → Clear credentials (or Clear credential storage). This removes installed user certificates and should stop the persistent lock-screen PIN request.
