Capture Android Network Traffic from Your Laptop Browser

Imagine testing an Android application and wanting to see its network activity from your laptop. You don't want to install another capture-control application, connect Ethernet adapters, or configure Internet Connection Sharing just to get started.

PCap Mobile offers a simpler workflow: capture traffic on your phone and use the Wi-Fi Transfer feature to access the supported browser interface from your laptop.

Monitor live packet-capture activity from your Android device.

No Ethernet Cable Required

Use a local Wi-Fi connection to access your phone's capture library from your laptop. There is no need for a dedicated Ethernet connection between the devices for file transfer.

No Internet Connection Sharing Setup

You do not need to turn your laptop into an Internet-sharing gateway simply to download capture files. The phone and laptop communicate over a reachable local network.

No Additional Laptop Capture-Control App

Use a compatible web browser to access the phone's Wi-Fi Transfer interface. You can manage supported capture operations from the browser without installing a separate capture-control program on the laptop.

Note: Wi-Fi Transfer and browser-based capture controls are Pro features. Both devices must be able to communicate over the local network.

Step 4: Select Applications and Protocols

Choose the applications and supported protocol filters relevant to your test before starting a capture.

Step 5: Start Capturing and Reproduce the Issue

Step 6: Download the PCAP File

Open the capture library and download the saved PCAP file to your laptop. You can inspect it later using a compatible packet-analysis tool.

More Features for Developers and Network Engineers

  • No-root packet capture: Uses Android's VPN service, with the required system permission.
  • Application filtering: Select installed apps to help focus your capture.
  • Protocol filtering: Work with supported traffic such as TCP, UDP, DNS, HTTPS and web traffic.
  • Live monitoring: View packet counts, bandwidth and other capture statistics.
  • Packet inspection: Review addresses, ports, protocol details, packet sizes and timing.
  • Hex viewer: Inspect raw packet data.
  • TCP/UDP stream inspection: Examine related packets together.

PCap Mobile PCAP capture library and export features

Save, organize and export your captures for later analysis.

Optional: Analyze Captures with Wireshark

PCap Mobile can inspect captures directly on your Android device. If you need a more advanced desktop analysis environment, download your PCAP file and open it in Wireshark.

Wireshark is optional. You do not need to install it just to use PCap Mobile's browser-based capture controls or download files.

Can It Read HTTPS Passwords and Messages?

Capturing encrypted HTTPS traffic does not automatically reveal the contents of encrypted requests and responses. You can still inspect available metadata, connection information, packet timing and other visible protocol details, but encrypted payloads generally remain unreadable without an appropriate authorized decryption setup.

Who Should Use PCap Mobile?

  • Android developers debugging API connectivity.
  • QA engineers investigating mobile application bugs.
  • Network engineers troubleshooting DNS, TCP and UDP communication.
  • VoIP developers investigating supported SIP and network traffic.
  • Cybersecurity students learning packet analysis.
  • Technical support teams collecting diagnostic PCAP files.
