From 7e277e7fb9e9690b027c7fc4034e664e9a472d8e Mon Sep 17 00:00:00 2001 From: inventory69 Date: Sun, 21 Dec 2025 11:09:29 +0100 Subject: [PATCH] =?UTF-8?q?=F0=9F=9A=80=20feat:=20Production=20release=20p?= =?UTF-8?q?reparation=20with=20GitHub=20Actions=20deployment?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ## Major Features - ✅ Battery optimized auto-sync (30 min interval, ~0.4%/day) - ✅ BuildConfig.DEBUG conditional logging (Logger.kt) - ✅ Settings UI cleanup (SSID field removed) - ✅ Interactive notifications (click opens app) - ✅ Post-reboot auto-sync (BootReceiver) - ✅ GitHub Actions deployment workflow ## Implementation Details ### Auto-Sync Architecture - WorkManager PeriodicWorkRequest (30 min intervals) - Gateway IP detection via network interface enumeration - Smart sync only when on home network - BootReceiver restarts monitoring after device reboot ### Logging System - Logger.kt object with BuildConfig.DEBUG checks - Debug logs only in DEBUG builds - Error/warning logs always visible - All components updated (NetworkMonitor, SyncWorker, WebDavSyncService, etc.) ### UI Improvements - Removed confusing SSID field from Settings - Gateway detection fully automatic - Material Design 3 info boxes - Cleaner, simpler user interface ### Notifications - PendingIntent opens MainActivity on click - setAutoCancel(true) for auto-dismiss - Broadcast receiver for UI refresh on sync ### GitHub Actions - Automated APK builds on push to main - Signed releases with proper keystore - 3 APK variants (universal, arm64-v8a, armeabi-v7a) - Semantic versioning: YYYY.MM.DD + build number - Comprehensive release notes with installation guide ## Documentation - README.md: User-friendly German guide - DOCS.md: Technical architecture documentation - GITHUB_ACTIONS_SETUP.md: Deployment setup guide ## Build Configuration - Signing support via key.properties - APK splits for smaller downloads -
