pointing to GitHub Discussions for non-bug feature discussions
This commit fixes the critical crash on Android 9 (API 28) that occurred when using
WorkManager Expedited Work for background sync operations.
## Root Cause
When setExpedited() is used in WorkManager, the CoroutineWorker must implement
getForegroundInfo() to return a ForegroundInfo object with a Foreground Service
notification. On Android 9-11, WorkManager calls this method, but the default
implementation throws: IllegalStateException: Not implemented
## Solution
- Implemented getForegroundInfo() in SyncWorker
- Returns ForegroundInfo with sync progress notification
- Android 10+: Sets FOREGROUND_SERVICE_TYPE_DATA_SYNC for proper service typing
- Added required Foreground Service permissions to AndroidManifest.xml
## Technical Changes
- SyncWorker.kt: Added getForegroundInfo() override
- NotificationHelper.kt: Added createSyncProgressNotification() factory method
- strings.xml: Added sync_in_progress UI strings (EN + DE)
- AndroidManifest.xml: Added FOREGROUND_SERVICE permissions
- Version updated to 1.7.1 (versionCode 18)
## Previously Fixed (in this release)
- Kernel-VPN compatibility (Wireguard interface detection)
- HTTP connection lifecycle optimization (SafeSardineWrapper)
- Stability improvements for sync sessions
## Testing
- Tested on Android 9 (API 28) - No crash on second app start
- Tested on Android 15 (API 35) - No regressions
- WiFi-connect sync working correctly
- Expedited work notifications display properly
Fixes#15
Thanks to @roughnecks for detailed bug report and testing!
- Added SafeSardineWrapper to properly close HTTP responses
- Prevents resource exhaustion after extended use (30-45 min)
- Added preemptive authentication to reduce 401 round-trips
- Added ProGuard rule for TextInclusionStrategy warnings
- Updated version to 1.7.1
Refs: #15
Fixes:
1. Notification click now opens ComposeMainActivity instead of legacy MainActivity
2. WiFi-Only toggle moved to its own 'Network Restriction' section at top of sync settings
3. Added hint explaining WiFi-Connect trigger is not affected by WiFi-Only setting
UI Changes:
- New section header: 'Network Restriction' / 'Netzwerk-Einschränkung'
- WiFi-Only toggle now clearly separated from sync triggers
- Info card shows when WiFi-Only is enabled explaining the exception
- Add WebDavSyncService.canSync() as single source of truth
- Add SyncGateResult data class for structured response
- Update MainViewModel.triggerManualSync() to use canSync()
- Update MainViewModel.triggerAutoSync() to use canSync() - FIXES onResume bug
- Update NoteEditorViewModel.triggerOnSaveSync() to use canSync()
- Update SettingsViewModel.syncNow() to use canSync()
- Update SyncWorker to use canSync() instead of direct prefs check
All 9 sync paths now respect WiFi-only setting through one central gate.
- SyncWorker: Add central WiFi-only guard before all sync operations
- NoteEditorViewModel: Add WiFi-only check before onSave sync trigger
- Prevents notes from syncing over 5G/mobile when WiFi-only is enabled
- Fixes: onSave sync ignored WiFi-only setting completely
- NEW: Configurable sync triggers (onSave, onResume, WiFi, Periodic, Boot)
- NEW: Offline mode toggle to disable all network features
- Various fixes and UI improvements
- Version bumped to 1.6.0 (code 14)
