+# deskhub Android
+
+Ersteller: M_Viper
+Produktname: deskhub
+
+Dieses Verzeichnis ist das vollständige, eigenständig baubare Android-Projekt für deskhub-Mitarbeiter.
+Die App ist nativ in Kotlin mit Jetpack Compose und Material 3 implementiert; sie enthält weder WebView
+noch PWA-Wrapper.
+
+## Funktionsumfang
+
+- Mitarbeiter-Login mit optionalem TOTP
+- Keystore-geschützte, widerrufbare API-Anmeldung
+- Ticketliste mit Volltextsuche sowie Status-, Zuständigkeits- und Abteilungsfiltern
+- Ticketdetails mit vollständigem Verlauf und internen Kommentaren
+- Änderung von Status und zuständiger Person
+- öffentliche Antworten und interne Notizen
+- Lade-, Leer- und Fehlerzustände sowie serverseitiger Logout
+
+Die App fragt beim Login die HTTPS-Adresse der deskhub-Installation ab, beispielsweise
+`https://support.example.de` oder `https://example.de/deskhub`. Klartext-HTTP ist nicht zugelassen.
+
+## Debug-APK bauen
+
+Voraussetzungen: JDK 17 und Android SDK 34.
+
+```powershell
+Set-Location C:\Users\Viper\Desktop\deskhub\mobile
+.\gradlew.bat testDebugUnitTest assembleDebug
+```
+
+Der Build exportiert die direkt installierbare, mit dem Android-Debugschlüssel signierte APK nach:
+
+`artifacts\deskhub-employee-debug.apk`
+
+Die normale Gradle-Ausgabe liegt unter `build\outputs\apk\debug\DeskHubMobile-debug.apk`.
+
+## Produktiv signierte Release-APK
+
+Der kundeneigene Keystore bleibt außerhalb des Projekts:
+
+```powershell
+keytool -genkeypair -v -keystore C:\secure\deskhub-release.jks -alias deskhub `
+  -keyalg RSA -keysize 4096 -validity 10000
+```
+
+Pfad und Zugangsdaten werden nur über Umgebungsvariablen bereitgestellt:
+
+```powershell
+$env:JAVA_HOME = 'C:\Program Files\Eclipse Adoptium\jdk-17.0.16.8-hotspot'
+$env:DESKHUB_RELEASE_STORE_FILE = 'C:\secure\deskhub-release.jks'
+$env:DESKHUB_RELEASE_STORE_PASSWORD = '<Keystore-Passwort>'
+$env:DESKHUB_RELEASE_KEY_ALIAS = 'deskhub'
+$env:DESKHUB_RELEASE_KEY_PASSWORD = '<Schlüssel-Passwort>'
+.\build-release.ps1
+```
+
+Das Skript erzeugt eine minifizierte, produktiv signierte APK unter
+`artifacts\deskhub-employee-release.apk`. Schlüssel und Passwörter werden nicht eingecheckt.

+#   Gradle start up script for POSIX generated by Gradle.
+#
+#   Important for running:
+#
+#   (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
+#       noncompliant, but you have some other compliant shell such as ksh or
+#       bash, then to run this script, type that shell name before the whole
+#       command line, like:
+#
+#           ksh Gradle
+#
+#       Busybox and similar reduced shells will NOT work, because this script
+#       requires all of these POSIX shell features:
+#         * functions;
+#         * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
+#           «${var#prefix}», «${var%suffix}», and «$( cmd )»;
+#         * compound commands having a testable exit status, especially «case»;
+#         * various built-in commands including «command», «set», and «ulimit».
+#
+#   Important for patching:
+#
+#   (2) This script targets any POSIX shell, so it avoids extensions provided
+#       by Bash, Ksh, etc; in particular arrays are avoided.
+#
+#       The "traditional" practice of packing multiple parameters into a
+#       space-separated string is a well documented source of bugs and security
+#       problems, so this is (mostly) avoided, by progressively accumulating
+#       options in "$@", and eventually passing that to Java.
+#
+#       Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
+#       and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
+#       see the in-line comments for details.
+#
+#       There are tweaks for specific operating systems such as AIX, CygWin,
+#       Darwin, MinGW, and NonStop.
+#
+#   (3) This script is generated from the Groovy template
+#       https://github.com/gradle/gradle/blob/HEAD/subprojects/plugins/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
