What does the error 'Create engine failed, error code: -7', mean when I initialize my app using an App ID?

February 03, 2022 08:56

Symptoms:

I'm running my app in the Unity Editor. The app works correctly the first time I run it, but subsequent runs show an error. After restarting the Editor, the error disappears.

Cause:

RTCEngine instances have a life cycle. This error is returned when you do not destroy the instance when the app or the Editor closes.

Resolution:

To resolve the 'create engine failed' error, Call IrtcEngine.Destroy() when you close your app. For example:

void OnApplicationQuit()
	{    	
         Debug.Log("OnApplicationQuit");
    	  if (mRtcEngine != null)
    	  {
        	mRtcEngine.LeaveChannel();
        	mRtcEngine.DisableVideoObserver();        	
             IRtcEngine.Destroy();
    	  }
	}

More Information:

The Destroy() API will be replaced by Dispose(). Please check the release notes for more information.
