Error with Azure AD Authentication in Unity for Android

Question

I'm building Azure AD authentication into my Android Application, using MSAL 3.x, however it is throwing errors when attempting to Acquire Token with User Interaction. The documentation for MSAL 3.x suggests that the parent activity or window is needed, however using Unity I'm pretty lost with this. Any help here would be much appreciated.

Answer 1

Depending on the version, Unity uses UnityPlayerActivity or UnityPlayerNativeActivity.
The Activity is necessary in MSAL.NET for Android applications because it provides the context for creating the interactive token acquisition procedure.
You might want to use the main/launcher activity in other instances.
You might consider extending a Unity Activity and implementing a hook for your MSAL.NET code in Unity.
