(Android™) Duo Auth API - Async Auth

See more Duo Auth MFA Examples

If you enable async, then your application will be able to retrieve real-time status updates from the authentication process, rather than receiving no information until the process is complete.

Note: This example requires Chilkat v9.5.0.89 or greater.
