							 Abstract= "The presented project provides a virtual learning environment for university courses tea-
ching app development using Android and Kotlin. It features both self-guided lessons and associated 
tests as well as practical app development tasks and associated self-assessed programming exercises. 
The well-known Moodle plug-in Virtual Programming Lab (VPL) serves as a starting point for the 
latter part. VPL gets extended by means for the usage of the Gradle build tool, the Android SDK tools 
and AndroidX tests for unit tests at the level of Android activities and fragments. In particular, the 
rather excessive resource requirements of the Gradle tool created numerous problems in the sand-
boxes used by VPL. These issues were addressed by configuring suitable VPL settings. In addition, 
problems associated with the proper usage of these settings had to be addressed in VPL Altogether 
the  proposed  virtual  learning  environment  provided  a  suitable means  for  learning  in  the  described  
field as determined by questionnaires send to students.",
