What is the most suitable approach if we are planning to use ACS (Azure Communication Services)'s Android Calling SDK on non-standard devices (smart glasses)?

Question

We are planning to add Microsoft Teams' meeting feature to our custom Unity app for a smart glass.

We found the following note on the ACS Android Calling SDK's document.

Is there a way to implement a feature using Azure Communication Services SDK which enables smart glass users to join a Teams meeting and send or receive screen shares through our custom Unity app on the device?

The followings are our development platform details and what we would like to implement:
■ Development tools details
- Unity 6000.0.49f1 (Platform: Android)
- MRTK3
- Snapdragon Spaces SDK ver1.0.4

■ What we would like to implement
Smart glasses users can...

• Join a Teams meeting from the custom Unity app.
• Share their screens (the view of smart glasses) in a Teams meeting
• Receive screen shares from Teams meeting attendees

Any information or advice would be appreciated.

Hi SatoKanade-5771 ,

Today, there is no supported approach to integrate Microsoft Teams meetings into a custom Unity application running on smart glasses using Azure Communication Services (ACS).

The ACS Android Calling SDK is designed for standard Android devices and supports Teams interoperability only at a basic calling level. It does not support custom rendering, screen sharing, or Unity-based media pipelines, and it depends on Android system components that are not available on smart glasses.

For your requirements:

Joining a Teams meeting from a Unity app on smart glasses
Not supported.

Sharing the smart-glass view as a screen share in a Teams meeting
Not supported.

Receiving and rendering Teams screen shares inside a Unity app
Not supported.

Teams meeting features such as screen sharing are tightly coupled to the official Teams client and are only supported on Teams-certified devices. ACS is intended for building custom calling experiences, not embedding full Teams meeting functionality into custom or non-certified devices.

If Teams participation is mandatory, the only supported path is using a Teams-certified device or vendor-provided Teams client.
If a custom Unity experience is mandatory, you must use pure ACS calling without Teams interoperability and implement your own collaboration logic.

There is currently no configuration, workaround, or SDK option that enables full Teams meeting support with screen sharing on smart glasses using ACS.

Answer 2

Hii @SatoKanade-5771,

Thank you for your question. Azure Communication Services (ACS) Calling SDK for Android is currently supported only on standard Android phones and tablets. Smart‑glasses and other XR/AR hardware fall under “non‑standard devices,” and therefore Microsoft cannot provide guaranteed or production‑level support for calling, video, or screen‑sharing scenarios on these devices.
Feasibility of Requirements

• Joining a Teams meeting:
  Yes, technically possible via ACS > Teams interoperability. Your app can join as an ACS user and participate seamlessly.
• Receiving video or screen‑share from other meeting participants:
  This may work depending on the device’s hardware acceleration and Unity rendering pipeline, but it is not officially supported.
• Sending smart‑glasses camera feed or screen share into a Teams meeting: This relies on ACS Raw Media APIs and advanced media processing. These APIs have not been validated for non‑standard Android devices and are not officially supported on such hardware, so functionality and performance cannot be guaranteed.

Smart‑glasses are outside the supported platform matrix. So, Please raise a support ticket before committing to this architecture.
