I'm trying to access a directory inside my app by using a document picker and setting the directoryURL property.
The document picker appears to be ignoring my directory input.
Is this not allowed? And if it isn't what is the best way to create a picker for these types internal app files?
A document picker can't access files inside the app bundle.
Use the methods in the Bundle class to load files from the app bundle. If you have documents in the app bundle that you want people to open in the app, copy the documents from the app bundle to the app's Documents directory. The FileManager class has a copyItem method to copy a file from one URL to another.
