ADFA-5646

The Add-ons Manager's discover-plugins arrow opens a website with no offline fallback, so tapping it offline was a dead end. It is now hidden when the device has no validated connection, or when Gradle offline mode is on.

Review by commit

1. 86062e7ac - ConnectivityObserver (common): a NetworkCallback in a callbackFlow. PluginManagerViewModel collects it into PluginManagerUiState.isOnline (default true, so a connected cold start does not flash-hide the arrow), and ManagerScreen gates the arrow on it.

2. 1c960a843 - review fixes. State comes from the callbacks' own data via OnlineNetworks, never from re-querying ConnectivityManager: in onLost, activeNetwork could still name the lost network and leave the arrow visible offline. The callback is registered before the initial sample, so a disconnect during startup is not lost. Online requires NET_CAPABILITY_VALIDATED, so a captive portal counts as offline. (Commit 4 replaces this commit's network set with the default network.) isNetworkConnected() is unchanged: it also gates Git clone, pull and push, and tightening those is outside this PR.

3. ae62b898c - the arrow is also hidden when Gradle offline mode is on (Preferences > Build & Run, BuildPreferences.isOfflineEnabled). The UI state exposes showDiscoverPlugins = isOnline && !isOfflineModeEnabled.

4. b810e7b53 - review fix: the observer uses registerDefaultNetworkCallback, so the callbacks and the initial sample (activeNetwork) follow the same network, a VPN included. Before, a NetworkRequest excluded VPNs, so a broken VPN left the arrow visible while the network underneath stayed validated. OnlineNetworks became DefaultNetworkState, which tracks that one network: a loss counts only for the current default, so a switch to a new default is not a disconnect.

5. 447fd9360 - merge repair. Today's merge of stage (c37a0d340, bringing in ADFA-6729 ADFA-6729: List only .cgp/.cgt files when installing from Downloads #2177) resolved its two conflicts to stage's side only:

   • Dropped: PluginModule.kt lost the BuildPreferences import (CI failed with Unresolved reference 'BuildPreferences') and the ConnectivityObserver Koin binding, which would have made the ViewModel's get() throw at runtime. ManagerScreen.kt lost the KDoc offline sentence.
   • Semantic conflict: ADFA-6729's new PluginManagerViewModelSourceDeleteTest built the ViewModel without this PR's two new parameters, so it now passes an always-online observer.
   • Checked: with --remerge-diff and a line-by-line comparison, no other line from either side was lost. :app compiles, PluginManagerViewModelTest (5), PluginManagerViewModelSourceDeleteTest (2), DefaultNetworkStateTest (8) and spotlessCheck pass.

Testing

• DefaultNetworkStateTest (8, plain JUnit): losing the default network reports offline; a switch to a new default stays online; a default network that loses validation (a broken VPN) reports offline; validation gates online; the initial sample loses to an earlier callback; a first callback reporting offline is sent; unchanged answers are not resent. With the current-default guard in onLost removed, the switch test fails.
• PluginManagerViewModelTest (5): isOnline on init and on change; the arrow shows only when online and not in offline mode. With the offline-mode check removed, showDiscoverPlugins_hiddenInOfflineModeEvenWhenOnline fails.
• spotlessCheck and :app:compileV8DebugKotlin pass on b810e7b53.
• On device, for 86062e7ac: turning Wi-Fi and mobile data off hides the arrow, and turning them on brings it back.
• On a Pixel 6 Pro (Android 17), with Wi-Fi as the only network, on both ae62b898c and b810e7b53, the arrow updated live each time with no navigation:
  • online, offline mode off: shown;
  • Wi-Fi off (the lost-only-network case): hidden;
  • Wi-Fi back on: hidden while the connection was not yet validated (about 5 s), shown once validated;
  • --offline on with Wi-Fi validated: hidden; off again: shown.
• Not tested on a device: switching between Wi-Fi and mobile data (the test phone's SIM had no data service), a captive portal, and a VPN. Unit tests cover the switch and a broken VPN.
• No new screen or layout change, so no font-scale check.

Summary

• Hide the discover-plugins action when the device’s default network lacks validated internet or Gradle offline mode is enabled.
• Update visibility as connectivity changes. Treat captive portals as offline.
• Risk: Device testing did not cover captive portals or Wi-Fi-to-mobile-data switching.
• Tests and checks: The supplied context reports six connectivity tests, five view-model tests, and a passing spotlessCheck. These results are author-reported and were not independently verified.
• Review findings: Severity counts are unavailable.

The plugin manager now tracks validated network connectivity and Gradle offline mode. It hides the Discover action when the device is offline or Gradle offline mode is enabled.

Changes: Plugin connectivity flow

Layer / File(s)	Summary
Connectivity observation and injection common/src/main/java/com/itsaky/androidide/utils/ConnectivityObserver.kt, app/src/main/java/com/itsaky/androidide/di/PluginModule.kt, common/src/test/java/com/itsaky/androidide/utils/DefaultNetworkStateTest.kt	Adds an Android observer for validated network status, injects it into the plugin manager, and tests network-state handling.
ViewModel state and offline-mode gating app/src/main/java/com/itsaky/androidide/ui/models/PluginManagerUiState.kt, app/src/main/java/com/itsaky/androidide/viewmodels/PluginManagerViewModel.kt, app/src/test/java/com/itsaky/androidide/viewmodels/PluginManagerViewModelTest.kt	The ViewModel updates UI state with connectivity and offline-mode values. UI state derives whether the Discover action can appear. Tests cover initial and changed connectivity and visibility conditions.
Discover action visibility app/src/main/java/com/itsaky/androidide/ui/compose/ManagerScreen.kt	The screen shows the Discover action on the Plugins tab only when UI state permits it.

Merge Risk: Minimal · up to b810e

Discover visibility follows connectivity and offline mode; no merge-blocking risk was identified.

Security architecture risk: Low · up to 86062

The new connectivity flow controls whether an existing discovery link is visible. It does not grant plugin installation authority or replace an access control. The link may briefly remain visible before connectivity is observed or if observation fails.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

• inferred — The inspected effect of an incorrect online value is limited to visibility of the discovery link, not expanded plugin-installation authority.

Trust Boundaries and Controls

• observed — Platform connectivity is treated as presentation state, not as proof of user identity, permission, or a safe destination. The Discover click still delegates to the existing URL opener.

Resilience and Maintainability Implications

• inferred — Normal cancellation releases the registered callback. If registration fails, collection may end without later corrections to the optimistic online value; that affects this UI availability cue, not an identified security control.

- Line 62: Update the startup sequence around
trySend(context.isNetworkConnected()) to register the network callback before
relying on the initial connectivity sample, and coordinate the sample with
callback delivery so a disconnect during startup cannot leave the flow reporting
stale connectivity.
- Line 47: Update the NetworkCallback flow so it derives internet connectivity
from the networks and capabilities delivered by callbacks, rather than calling
context.isNetworkConnected(). Track callback-delivered state in callback order,
and handle onLost using the remaining tracked networks so losing one network
does not report disconnection while another is available.

IMPORTANT

• ConnectivityObserver.kt:50 - onLost can re-report the lost network as online

MINOR

• ContextUtils.kt:127 (anchored at ConnectivityObserver.kt:58) - online check ignores NET_CAPABILITY_VALIDATED

[hal-eisen-adfa]

I feel like the sense of this PR is backwards. Cogo is intended to be primarily offline so the icon should default to not visible, and only appear when the app is online.
