## 🔄 Auto-Sync Implementierung
### WorkManager Periodic Task
Der Auto-Sync basiert auf **WorkManager** mit folgender Konfiguration:
```kotlin
val constraints = Constraints.Builder()
.setRequiredNetworkType(NetworkType.UNMETERED) // Nur WiFi
.build()
val syncRequest = PeriodicWorkRequestBuilder<SyncWorker>(
30, TimeUnit.MINUTES, // Alle 30 Minuten
10, TimeUnit.MINUTES // Flex interval
)
.setConstraints(constraints)
.build()
```
**Warum WorkManager?**
- ✅ Läuft auch wenn App geschlossen ist
- ✅ Automatischer Restart nach Device Reboot
- ✅ Battery-efficient (Android managed)
- ✅ Garantierte Ausführung bei erfüllten Constraints
### Network Detection
Statt SSID-basierter Erkennung (Android 13+ Privacy-Probleme) verwenden wir **Gateway IP Comparison**:
```kotlin
fun isInHomeNetwork(): Boolean {
val gatewayIP = getGatewayIP() // z.B. 192.168.0.1
val serverIP = extractIPFromUrl(serverUrl) // z.B. 192.168.0.188
return isSameNetwork(gatewayIP, serverIP) // Prüft /24 Netzwerk
}
```
**Vorteile:**
- ✅ Keine Location Permissions nötig
- ✅ Funktioniert mit allen Android Versionen
- ✅ Zuverlässig und schnell
### Sync Flow
```
1. WorkManager wacht auf (alle 30 Min)
2. Check: WiFi connected?
3. Check: Same network as server?
4. Load local notes
5. Upload neue/geänderte Notes → Server
6. Download remote notes ← Server
7. Merge & resolve conflicts
8. Update local storage
9. Show notification (if changes)
```
---
## 🔋 Akku-Optimierung
### Verbrauchsanalyse
| Komponente | Frequenz | Verbrauch | Details |
|------------|----------|-----------|---------|
| WorkManager Wakeup | Alle 30 Min | ~0.15 mAh | System wacht auf |
| Network Check | 48x/Tag | ~0.03 mAh | Gateway IP check |
| WebDAV Sync | 2-3x/Tag | ~1.5 mAh | Nur bei Änderungen |
| **Total** | - | **~12 mAh/Tag** | **~0.4%** bei 3000mAh |
### Optimierungen
1. **IP Caching**
```kotlin
private var cachedServerIP: String? = null
// DNS lookup nur 1x beim Start, nicht bei jedem Check
```
2. **Throttling**
```kotlin
private var lastSyncTime = 0L
private const val MIN_SYNC_INTERVAL_MS = 60_000L // Max 1 Sync/Min
```
3. **Conditional Logging**
```kotlin
object Logger {
fun d(tag: String, msg: String) {
if (BuildConfig.DEBUG) Log.d(tag, msg)
}
}
```
4. **Network Constraints**
- Nur WiFi (nicht mobile Daten)
- Nur wenn Server erreichbar
- Keine permanenten Listeners
---
## 📦 WebDAV Sync Details
### Upload Flow
```kotlin
suspend fun uploadNotes(): Int {
val localNotes = storage.loadAllNotes()
var uploadedCount = 0
for (note in localNotes) {
if (note.syncStatus == SyncStatus.PENDING) {
val jsonContent = note.toJson()
val remotePath = "$serverUrl/${note.id}.json"
sardine.put(remotePath, jsonContent.toByteArray())
note.syncStatus = SyncStatus.SYNCED
storage.saveNote(note)
uploadedCount++
}
}
return uploadedCount
}
```
### Download Flow
```kotlin
suspend fun downloadNotes(): DownloadResult {
val remoteFiles = sardine.list(serverUrl)
var downloadedCount = 0
var conflictCount = 0
for (file in remoteFiles) {
if (!file.name.endsWith(".json")) continue
val content = sardine.get(file.href)
val remoteNote = Note.fromJson(content)
val localNote = storage.loadNote(remoteNote.id)
if (localNote == null) {
// Neue Note vom Server
storage.saveNote(remoteNote)
downloadedCount++
} else if (localNote.modifiedAt < remoteNote.modifiedAt) {
// Server hat neuere Version
storage.saveNote(remoteNote)
downloadedCount++
} else if (localNote.modifiedAt > remoteNote.modifiedAt) {
// Lokale Version ist neuer → Conflict
resolveConflict(localNote, remoteNote)
conflictCount++
}
}
return DownloadResult(downloadedCount, conflictCount)
}
```
### Conflict Resolution
Strategie: **Last-Write-Wins** mit **Conflict Copy**
```kotlin
fun resolveConflict(local: Note, remote: Note) {
// Remote Note umbenennen (Conflict Copy)
val conflictNote = remote.copy(
id = "${remote.id}_conflict_${System.currentTimeMillis()}",
title = "${remote.title} (Konflikt)"
)
storage.saveNote(conflictNote)
// Lokale Note bleibt
local.syncStatus = SyncStatus.SYNCED
storage.saveNote(local)
}
```
---
## 🔔 Notifications
### Notification Channels
```kotlin
val channel = NotificationChannel(
"notes_sync_channel",
"Notizen Synchronisierung",
NotificationManager.IMPORTANCE_DEFAULT
)
```
### Success Notification
```kotlin
fun showSyncSuccess(context: Context, count: Int) {
val intent = Intent(context, MainActivity::class.java)
val pendingIntent = PendingIntent.getActivity(context, 0, intent, FLAGS)
val notification = NotificationCompat.Builder(context, CHANNEL_ID)
.setContentTitle("Sync erfolgreich")
.setContentText("$count Notizen synchronisiert")
.setContentIntent(pendingIntent) // Click öffnet App
.setAutoCancel(true) // Dismiss on click
.build()
notificationManager.notify(NOTIFICATION_ID, notification)
}
```
---
## 🛡️ Permissions
Die App benötigt **minimale Permissions**:
```xml
<!-- Netzwerk -->
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />
<!-- Notifications -->
<uses-permission android:name="android.permission.POST_NOTIFICATIONS" />
<!-- Boot Receiver -->
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
<!-- Battery Optimization (optional) -->
<uses-permission android:name="android.permission.REQUEST_IGNORE_BATTERY_OPTIMIZATIONS" />
```
**Keine Location Permissions!**
Frühere Versionen benötigten `ACCESS_FINE_LOCATION` für SSID-Erkennung. Jetzt verwenden wir Gateway IP Comparison.
---

zipalign -v 4 app-release-unsigned.apk app-release.apk
```
---
## 🐛 Debugging
### LogCat Filter
```bash
# Nur App-Logs
adb logcat -s SimpleNotesApp NetworkMonitor SyncWorker WebDavSyncService
# Mit Timestamps
adb logcat -v time -s SyncWorker
# In Datei speichern
adb logcat -s SyncWorker > sync_debug.log
```
### Common Issues
**Problem: Auto-Sync funktioniert nicht**
```
Lösung: Akku-Optimierung deaktivieren
Settings → Apps → Simple Notes → Battery → Don't optimize
```
**Problem: Server nicht erreichbar**
```
Check:
1. Server läuft? → docker-compose ps
2. IP korrekt? → ip addr show
3. Port offen? → telnet 192.168.0.188 8080
4. Firewall? → sudo ufw allow 8080
```
**Problem: Notifications kommen nicht**
```
Check:
1. Notification Permission erteilt?
2. Do Not Disturb aktiv?
3. App im Background? → Force stop & restart
```

# GitHub Actions Setup Guide
This guide explains how to set up the GitHub Actions workflow for automated APK builds with proper signing.
## Overview
The workflow in `.github/workflows/build-production-apk.yml` automatically:
- Builds signed APKs on every push to `main`
- Generates version numbers using `YYYY.MM.DD` + build number
- Creates 3 APK variants (universal, arm64-v8a, armeabi-v7a)
- Creates GitHub releases with all APKs attached
## Prerequisites
- GitHub CLI (`gh`) installed
- Java 17+ installed (for keytool)
- Git repository initialized with GitHub remote
## Step 1: Generate Signing Keystore
⚠️ **IMPORTANT**: Store the keystore securely! Without it, you cannot publish updates to your app.
```bash
# Navigate to project root
cd /path/to/simple-notes-sync
# Generate keystore (replace values as needed)
keytool -genkey -v \
-keystore android/app/simple-notes-release.jks \
-keyalg RSA \
-keysize 2048 \
-validity 10000 \
-alias simple-notes
# You will be prompted for:
# - Keystore password (remember this!)
# - Key password (remember this!)
# - Your name, organization, etc.
```
**Store these securely:**
- Keystore password
- Key password
- Alias: `simple-notes`
- Keystore file: `android/app/simple-notes-release.jks`
⚠️ **BACKUP**: Make a backup of the keystore file in a secure location (NOT in the repository).
## Step 2: Base64 Encode Keystore
```bash
# Create base64 encoded version
base64 android/app/simple-notes-release.jks > simple-notes-release.jks.b64
# Or on macOS:
base64 -i android/app/simple-notes-release.jks -o simple-notes-release.jks.b64
```
## Step 3: Set GitHub Secrets
Using GitHub CLI (recommended):
```bash
# Set KEYSTORE_BASE64 secret
gh secret set KEYSTORE_BASE64 < simple-notes-release.jks.b64
# Set KEYSTORE_PASSWORD (will prompt for input)
gh secret set KEYSTORE_PASSWORD
# Set KEY_PASSWORD (will prompt for input)
gh secret set KEY_PASSWORD
# Set KEY_ALIAS (value: simple-notes)
printf "simple-notes" | gh secret set KEY_ALIAS
```
Or manually via GitHub web interface:
1. Go to repository Settings → Secrets and variables → Actions
2. Click "New repository secret"
3. Add these secrets:
- `KEYSTORE_BASE64`: Paste content of `simple-notes-release.jks.b64`
- `KEYSTORE_PASSWORD`: Your keystore password
- `KEY_PASSWORD`: Your key password
- `KEY_ALIAS`: `simple-notes`
## Step 4: Verify Setup
```bash
# Check secrets are set
gh secret list
# Expected output:
# KEYSTORE_BASE64 Updated YYYY-MM-DD
# KEYSTORE_PASSWORD Updated YYYY-MM-DD
# KEY_PASSWORD Updated YYYY-MM-DD
# KEY_ALIAS Updated YYYY-MM-DD
```
## Step 5: Cleanup
```bash
# Remove sensitive files (they're in .gitignore, but double-check)
rm simple-notes-release.jks.b64
rm -f android/key.properties # Generated by workflow
# Verify keystore is NOT tracked by git
git status | grep -i jks
# Should return nothing
```
## Step 6: Trigger First Build
```bash
# Commit and push to main
git add .
git commit -m "🚀 feat: Add GitHub Actions deployment workflow"
git push origin main
# Or manually trigger workflow
gh workflow run build-production-apk.yml
```
## Verification
1. Go to GitHub repository → Actions tab
2. Check workflow run status
3. Once complete, go to Releases tab
4. Verify release was created with 3 APK variants
5. Download and test one of the APKs
## Troubleshooting
### Build fails with "Keystore not found"
- Check `KEYSTORE_BASE64` secret is set correctly
- Verify base64 encoding was done without line breaks
### Build fails with "Incorrect password"
- Verify `KEYSTORE_PASSWORD` and `KEY_PASSWORD` are correct
- Re-set secrets if needed
### APK files not found
- Check build logs for errors in assembleRelease step
- Verify APK output paths match workflow expectations
### Updates don't work
- Ensure you're using the same keystore for all builds
- Verify `applicationId` in build.gradle.kts matches
## Security Notes
- ✅ Keystore is base64-encoded in GitHub secrets (secure)
- ✅ Passwords are stored in GitHub secrets (encrypted)
-`key.properties` and `.jks` files are in `.gitignore`
- ⚠️ Never commit keystore files to repository
- ⚠️ Keep backup of keystore in secure location
- ⚠️ Don't share keystore passwords
## Versioning
Versions follow this pattern:
- **Version Name**: `YYYY.MM.DD` (e.g., `2025.01.15`)
- **Version Code**: GitHub run number (e.g., `42`)
- **Release Tag**: `vYYYY.MM.DD-prod.BUILD` (e.g., `v2025.01.15-prod.42`)
This ensures:
- Semantic versioning based on release date
- Incremental version codes for Play Store compatibility
- Clear distinction between builds
## APK Variants
The workflow generates 3 APK variants:
1. **Universal APK** (~5 MB)
- Works on all devices
- Larger file size
- Recommended for most users
2. **arm64-v8a APK** (~3 MB)
- For modern devices (2018+)
- Smaller, faster
- 64-bit ARM processors
3. **armeabi-v7a APK** (~3 MB)
- For older devices
- 32-bit ARM processors
Users can choose based on their device - Obtanium auto-updates work with all variants.

## ⚙️ Server Konfiguration
**Standard-Credentials:**
- Username: `noteuser`
- Password: Siehe `.env` im `server/` Verzeichnis
**Server-URL:**
- Lokal: `http://localhost:8080/`
- Im Netzwerk: `http://YOUR_IP:8080/`
IP-Adresse finden:
```bash
ip addr show | grep "inet " | grep -v 127.0.0.1
```
## 📱 Android App Setup
### Vorraussetzungen
- Android Studio Hedgehog (2023.1.1) oder neuer
- JDK 17
- Min SDK 24 (Android 7.0)
- Target SDK 34 (Android 14)
### In App konfigurieren
1. App starten
2. Einstellungen öffnen
3. Server-URL eintragen (z.B. `http://192.168.1.100:8080/`)
4. Username & Passwort eingeben
5. Heim-WLAN SSID eingeben
6. "Verbindung testen"
## 🔧 Entwicklung
### Server-Management
```bash
# Status prüfen
docker-compose ps
# Logs anschauen
docker-compose logs -f
# Neustarten
docker-compose restart
# Stoppen
docker-compose down
```
### Android-Build
**Option 2: Selbst bauen**
```bash
cd android
./gradlew assembleDebug
# APK Location:
# app/build/outputs/apk/debug/app-debug.apk
# APK: android/app/build/outputs/apk/debug/app-debug.apk
```
## 🧪 Testing
### WebDAV Server
### Server-Test
Der Server läuft als Docker-Container und speichert deine Notizen.
```bash
# Testdatei hochladen
echo '{"id":"test","title":"Test","content":"Hello"}' > test.json
curl -u noteuser:password -T test.json http://localhost:8080/test.json
# Datei abrufen
curl -u noteuser:password http://localhost:8080/test.json
# Datei löschen
curl -u noteuser:password -X DELETE http://localhost:8080/test.json
```
### Android-App
1. Notiz erstellen → speichern → in Liste sichtbar ✓
2. WLAN verbinden → Auto-Sync ✓
3. Server offline → Fehlermeldung ✓
4. Konflikt-Szenario → Auflösung ✓
## 📦 Deployment
### Server (Production)
**Option 1: Lokaler Server (Raspberry Pi, etc.)**
```bash
cd server
cp .env.example .env
nano .env # Passwort anpassen!
docker-compose up -d
```
**Option 2: VPS (DigitalOcean, Hetzner, etc.)**
**Server testen:**
```bash
# Mit HTTPS (empfohlen)
# Zusätzlich: Reverse Proxy (nginx/Caddy) + Let's Encrypt
curl -u noteuser:dein_passwort http://192.168.0.XXX:8080/
```
### Android App
```bash
# Release Build
./gradlew assembleRelease
# APK signieren
# Play Store Upload oder Direct Install
```
## 🔐 Security
**Entwicklung:**
- ✅ HTTP Basic Auth
- ✅ Nur im lokalen Netzwerk
**Produktion:**
- ⚠️ HTTPS mit SSL/TLS (empfohlen)
- ⚠️ Starkes Passwort
- ⚠️ Firewall-Regeln
- ⚠️ VPN für externen Zugriff
## 🐛 Troubleshooting
### Server startet nicht
```bash
# Port bereits belegt?
sudo netstat -tlnp | grep 8080
# Logs checken
docker-compose logs webdav
```
### Android kann nicht verbinden
- Ist Android im gleichen WLAN?
- Ist die Server-IP korrekt?
- Firewall blockiert Port 8080?
- Credentials korrekt?
```bash
# Ping zum Server
ping YOUR_SERVER_IP
# Port erreichbar?
telnet YOUR_SERVER_IP 8080
```

---
**Project Start:** 19. Dezember 2025
**Status:** 🚧 In Development
## 🚀 Schnellstart
1. **Server starten** (siehe oben)
2. **App installieren** und öffnen
3. **Einstellungen öffnen** (⚙️ Symbol oben rechts)
4. **Server konfigurieren:**
- Server-URL: `http://192.168.0.XXX:8080/notes`
- Benutzername: `noteuser`
- Passwort: (aus `.env` Datei)
- Auto-Sync: **AN**
5. **Fertig!** Notizen werden jetzt automatisch synchronisiert
---
## 💡 Wie funktioniert Auto-Sync?
Die App prüft **alle 30 Minuten**, ob:
- ✅ WLAN verbunden ist
- ✅ Server im gleichen Netzwerk erreichbar ist
- ✅ Neue Notizen vorhanden sind
Wenn alle Bedingungen erfüllt → **Automatische Synchronisierung**
**Wichtig:** Funktioniert nur im selben Netzwerk wie der Server (kein Internet-Zugriff nötig!)
---
## 🔋 Akkuverbrauch
| Komponente | Verbrauch/Tag |
|------------|---------------|
| WorkManager (alle 30 Min) | ~0.3% |
| Netzwerk-Checks | ~0.1% |
| **Total** | **~0.4%** |
Bei einem 3000 mAh Akku entspricht das ~12 mAh pro Tag.
---
## 📱 Screenshots
_TODO: Screenshots hinzufügen_
---
## 🛠️ Technische Details
Mehr Infos zur Architektur und Implementierung findest du in der [technischen Dokumentation](DOCS.md).
**Stack:**
- **Android:** Kotlin, Material Design 3, WorkManager
- **Server:** Docker, WebDAV (bytemark/webdav)
- **Sync:** Sardine Android (WebDAV Client)
---
## 🐛 Troubleshooting
### Server nicht erreichbar
```bash
# Server Status prüfen
docker-compose ps
# Logs ansehen
docker-compose logs -f
# IP-Adresse finden
ip addr show | grep "inet " | grep -v 127.0.0.1
```
### Auto-Sync funktioniert nicht
1. **Akku-Optimierung deaktivieren**
- Einstellungen → Apps → Simple Notes → Akku → Nicht optimieren
2. **WLAN Verbindung prüfen**
- App funktioniert nur im selben Netzwerk wie der Server
3. **Server-Status in App prüfen**
- Settings → Server-Status sollte "Erreichbar" zeigen
Mehr Details in der [Dokumentation](DOCS.md).
