问题
I successfully created EmbeddedAssistantStub using the below code.
EmbeddedAssistantGrpc.EmbeddedAssistantStub mAssistantService = EmbeddedAssistantGrpc.newStub(channel)
.withCallCredentials(MoreCallCredentials.from(
Credentials.fromResource(mClientId,mRefreshToken,mAccessToken)
));
After this i passed audio data to StreamObserver, At that time below exxception was occured.

They messed up with their backend. Just wait until they fix it. Here is the github thread regarding that bug: https://github.com/googlesamples/assistant-sdk-python/issues/138
回答2:
They fixed this issue at back-end.
@JHorseman : Thanks for the support.
