(Android™) OneDrive -- List Non-Root Directory

See more OneDrive Examples

This gets the collection of DriveItem children for a non-root DriveItem. This is the same as for getting the children for the root DriveItem, except the URL includes the path to the desired non-root DriveItem.

Note: This example requires Chilkat v9.5.0.97 or greater.
