I need an option for a teacher to pass a file to a student (Airdrop?) who can then use it to launch my App or open it from my App. Is it anything to do with MobileApplication.HandleURL
Yes. The other piece of the puzzle you’ll need is to declare a file type for these files. The teacher’s app needs to be marked as the creator of the file type and the student app needs to be declared as editor or viewer, depending on what they’re allowed to do with it.
After Airdropping the file to the iPad I managed to launch the App on the iPad by selecting the File>Share what event in the App is triggered for me to process the file?
HandleUrl. You’ll get a file url in there that you can use to get access to the file.
