+# YourPart Native Android
+
+Native Android-App fuer YourPart als paralleler Aufbau zur bestehenden Capacitor-App.
+
+## Entscheidungen
+
+- Pfad: `/android/native`
+- Sprache: Kotlin
+- UI: Jetpack Compose
+- App-ID Debug/Local: `de.yourpart.nativeapp.local.debug`
+- App-ID Production Release: `de.yourpart.nativeapp`
+- minSdk: 26
+- compileSdk/targetSdk: 36
+- Flavors: `local`, `staging`, `production`
+- Build Types: `debug`, `release`
+
+## Kommandos
+
+```bash
+cd android/native
+../android/gradlew -p . :app:assembleLocalDebug
+../android/gradlew -p . :app:installLocalDebug
+./scripts/assemble-local-debug.sh
+```
+
+## Emulator-Backend
+
+Der Android-Emulator erreicht den Host-Rechner ueber `10.0.2.2`.
+
+Der `local` Flavor nutzt:
+
+- API: `http://10.0.2.2:2020`
+- Socket.IO: `http://10.0.2.2:2020`
+- Daemon: `ws://10.0.2.2:2021`
