Notes

• On Android 7.0 (API 24) and above, the trigger uses the NetworkCallback API for efficient network monitoring.
• On older Android versions, the trigger monitors the CONNECTIVITY_ACTION broadcast.
• The trigger compares the new IP address with the previous one and only fires if there's an actual change.
• The trigger will not fire if the IP address cannot be determined (shown as "?").
• The previous IP address is stored in settings to detect changes across app restarts.
• The trigger fires for IPv4 address changes.
