问题描述
我使用以下代码成功创建了EmbeddedAssistantStub.
I successfully created EmbeddedAssistantStub using the below code.
EmbeddedAssistantGrpc.EmbeddedAssistantStub mAssistantService = EmbeddedAssistantGrpc.newStub(channel)
.withCallCredentials(MoreCallCredentials.from(
Credentials.fromResource(mClientId,mRefreshToken,mAccessToken)
));
此后，我将音频数据传递给StreamObserver，当时发生了低于感受的情况.
After this i passed audio data to StreamObserver, At that time below exxception was occured.
