PCAPdroid is an open source app which lets you monitor and export the network traffic of your device.
The app simulates a VPN to achieve non-root capture but, contrary to a VPN, the traffic is processed locally into the device.
Features:
- Log and examine the connections made by user and system apps
- Extract the SNI, DNS query, HTTP request, HTTP URL and the remote IP address
- Create rules to filter out the good traffic and easily spot anomalies
- Dump the traffic into a PCAP file, download it from a browser, or stream it to a remote receiver for real time analysis (e.g. wireshark)
- Use the app in combination with mitmproxy to decrypt HTTPS/TLS traffic (technical knowledge required)
- On rooted devices, capture the traffic while other VPN apps are running
Paid Features:
- Detect malicious connections by using third-party blacklists

Some features of PCAPdroid can be integrated into a third-party app to provide packet capture capabilities.
- For rooted devices, the pcapd daemon can be directly integrated into your APK to capture network packets.
- For all the devices, PCAPdroid exposes an API to control the packet capture and send the captured packets via UDP to your app. This requires to install PCAPdroid along with your app.
- zdtun: TCP/UDP/ICMP connections proxy
- nDPI: deep packet inspection library, used to extract the connections metadata
