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.
