The process I went through:

• In the app I have the location set to being the removable SD card
• I copy the attached course file into /sdcard0/Android/data/org.digitalcampus.mobile.learning/files/download
• I open up the app and the course appears to be auto installed
• However the course zip file is not removed from the download directory and the folder for the course is not generated on in the modules directory
• The course appears on the homepage (so has been loaded into the app db)
• But when trying to open, the app crashes (stack trace below)

It seems like this course install process is using a different reference for the location of the course files/xml.

In any case there seem to be a mismatch in the directories used for installing the course depending on whether installed by downloading from the server and into the app, or when installing directly by copying onto the phone (either sdcard or internal) - although the video files are being stored in the sdcard.
