Benötigte Android Berechtigungen:

Tipps zum Clonen von Github in AndroidStudio (nur für Entwickler):

Wenn das Clonen bzw. das Öffnen des Projektes wegen eines ausgegrauten "Use default gradle wrapper (not configured for the current project)" nicht möglich ist, dann

  • das Projekt nochmal normal als "Open an existing Android Studio project" öffnen und im "Gradle Sync" Dialog einfach OK klicken
  • Wenn nötig unter Settings => Version Control das "Unregistered Root" auswählen und auf das grüne "+" klicken, fertig
