onPreviewFrame MLKitImageLabeling error on Android #1192

Occasionally the MLKitImageLabeling camera will fail with the below exception. I think it loses reference to the JavaScript method.

System.err: com.tns.NativeScriptException:

When putting the phone to and out of sleep I also sometimes start getting the below exception.

Can you share the code that triggers these?
