PCAPdroid

No-root network monitor and traffic dump tool for Android devices
PCAPdroid is a privacy-friendly app which lets you track and analyze the connections made by the other apps in your device.
It also allows you to export a PCAP dump of the traffic, inspect HTTP, decrypt TLS traffic and much more.

PCAPdroid simulates a VPN in order to capture the network traffic without root. It does not use a remote VPN server. All the data is processed locally on the device.

Features:

* Log and examine the connections made by user and system apps
* Extract the SNI, DNS query, HTTP URL and the remote IP address
* Inspect HTTP requests and replies thanks to the built-in decoders
* Inspect the full connections payload as hexdump/text
* Decrypt the HTTPS/TLS traffic and export the SSLKEYLOGFILE
* Dump the traffic to a PCAP file, download it from a browser, or stream it to a remote receiver for real time analysis (e.g. wireshark)
* Create rules to filter out the good traffic and easily spot anomalies
* Identify the country and ASN of remote server via offline db lookups
* On rooted devices, capture the traffic while other VPN apps are running

If you plan to use PCAPdroid to perform packet analysis, please check out the specific section of the manual.
