Can a mobile app programmatically trigger the OneDrive mobile app?

Hi,

I am developing a native mobile application (Android and iOS) and I would like to clarify
what is officially supported when interacting with OneDrive on mobile devices.

Specifically, I would like to know:
- Is there any supported way (Android Intent, iOS URL scheme, or similar)
  for a third-party mobile app to programmatically trigger the OneDrive mobile app
  to create folders or upload files?
- Or is Microsoft Graph API the only supported approach
  to create folders and upload files to OneDrive / SharePoint from a mobile application?

I am looking for an official clarification on the supported approach.

Thank you.
