Für einige wenige Bilder reicht das Laden von Ressourcen im Hauptanwendungs-Thread möglicherweise aus, jedoch nicht für Hunderte. Möglicherweise müssen Sie in eine [Bildlade-Bibliothek] (https://android-arsenal.com/tag/46) wie [Picasso] (http://square.github.io/picasso/) schauen kann diese Bilder auf Hintergrundthreads laden. – CommonsWare
