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!
