How to do it
Connectivity checks are managed at system level by Android; disabling captive portal detection requires running an adb shell command against the global settings.
Menu names may differ by device and version.
What you lose
The device will not automatically show captive portal login screens on public Wi-Fi networks.
What is collected
Ip address, request timestamps, http response headers.
The checks exist to detect restricted local networks and launch captive-portal login pages when required.
