📝 WalkthroughWalkthroughVPN stop requests now use explicit service intents. ChangesVPN service control
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟡 Moderate · up to The change improves VPN stop delivery and duplicate-connect handling, but lifecycle races remain: stop operations can overlap with connection setup, and cleanup may remove status tracking before teardown is confirmed. This can allow late reconnection or lost VPN status updates, so merge should wait for these issues to be fixed or explicitly accepted. Sequence Diagram(s)sequenceDiagram

Pull request overview
This pull request updates the VPN stop flow to route stop requests directly to LanternVpnService (instead of relying on broadcasts), and tightens service lifecycle handling to avoid losing VPN status updates during failure/edge cases.
Changes:
- Switched VPN stop actions from broadcast intents to explicit service intents in
MainActivity,NotificationHelper, andQuickTileService. - Adjusted
LanternVpnServiceconnect flow to ignore duplicate in-flight connect attempts instead of throwing. - Made failure-path cleanup in
LanternVpnServiceconditional to avoid unregistering the status receiver while a tunnel may still be active.

- Around line 456-460: Move acquisition of connectInFlight before all shared VPN
setup so duplicate requests cannot mutate service state or trigger cleanup;
ensure setup failures release the guard correctly. Update performStopVPN() to
cancel or invalidate and await the active connection operation before performing
cleanup, preventing late completion from publishing Connected or restoring the
tunnel.
- Around line 497-500: Update the cleanup logic around the vpnConnected check
and performStopVPN so failed or in-flight native VPN operations preserve an
unknown state rather than being treated as disconnected. Keep the status
receiver while connectInFlight is true, and invoke serviceCleanUp only after
Mobile.isVPNConnected confirms disconnection or stopVPNTunnel confirms teardown
without swallowing failure state.

This pull request refactors how the app stops the VPN service, ensuring that stop requests are reliably delivered even if the status receiver is not active. It replaces broadcast intents with direct service intents for stopping the VPN, improves error handling for duplicate connect attempts, and prevents premature cleanup of the status receiver when a VPN tunnel is still active.
