Capture network traffic programmatically (no root)

Question

Answer 1

The de-facto appraoch to packet sniffing in Android without root is loop-back VPNService. Creating a VPNService app and activating it, will force all traffic in the device to go through your newly created virtual interface which is managed by a userspace application, where you will be receiving IP Packets by reading from the virtual interface.
