Meta Voice SDK - NullPointerException with Looper on Activation

Unity Engine
1

I am encountering a NullPointerException in the Meta Voice SDK while attempting to activate AppVoiceExperience in my Unity project. The error occurs when the SDK tries to access Android’s Looper.mQueue during initialization. I am on Mac.

I am developing for the Meat Quest 3. I have the Latest version of the Meta Voice SDK installed (v71) as well as the latest version of the Meta Core SDK. I do NOT have the Meta All in One SDK installed. I’ve set up all the Wit voice configuration files as well.

appVoiceExperience.Activate();

This code is causing the error. When I run it in game mode. I dont get an error

Here is the exact error:

This happens regardless of whether I call Activate() in the Awake, Start, or through a delayed coroutine. The same error persists in all cases.

Here are some of my key observations:

  1. Im actually also getting the exception before my script is even called.
  2. Awake in VoiceManager is successfully called, but Start encounters the NullPointerException.
  3. Even delaying the Activate() call with a coroutine or button click does not resolve the issue.
  4. The required permissions (RECORD_AUDIO, INTERNET, FOREGROUND_SERVICE) are all declared in the AndroidManifest.xml, and the app has been granted these permissions on the device.

I have the same problem.

Same here! The docs only have Play mode information, there’s nothing about building the game. But apparently things can go wrong.

Any Meta dev here?

Facing the same issue with Unity 6. Could anybody help?
