Cloud Speech API返回码= UNAUTHENTICATED,cause = java.io.IOException:获取服务帐户的访问令牌时出错:

我在我的应用中使用Google Cloud Speech API(通过gRPC进行StreamingRecognize)进行语音识别.我在
Android设备API级别上验证了问题< 23.

我不是每次都会收到此错误,但仅限于特定情况.我有两项活动.我们叫A和B.

活动A有一个按钮,它启动活动B.
活动B与Google Cloud Speech API通信并在TextView中显示结果.

按照以下步骤操作后出现此错误(在Samsung GT-P5110(Android 4.2.2)上):

>开始活动A – >按下按钮启动活动B.

//第一次一切都好的我从服务器收到结果并显示此信息.

>关闭活动B(按后退按钮或调用onBackPressed或完成).
>按按钮开始活动B.

//在这一刻我得到错误,如上所示.

之后,我在联想A1000(API 5.0.1)和小米Mi4c(5.0.1)上出现此错误:

>开始活动A – >按下按钮启动活动B.
>关闭活动B(按后退按钮或调用onBackPressed或完成).
>按按钮开始活动B.

// 一切正常

>关闭活动B(按后退按钮或调用onBackPressed或完成).
>最小化应用程序.
> 5-6分钟后再回到活动A.
>开始活动B.

//在这一刻我总是得到这个错误.

重新启动应用程序后,一切正常,但重新打开活动B后出现错误.

谁知道我怎么能解决这个问题?

我使用Play服务动态安全提供程序(It is required for gRPC).
我安装了最新版Google Play服务(9.6.83).它无法解决问题.

我通过以下代码创建ManagedChannel:

GoogleCredentials creds = GoogleCredentials.fromStream(credentials);
    creds = creds.createScoped(OAUTH2_SCOPES);
    OkHttpChannelProvider provider = new OkHttpChannelProvider();
    OkHttpChannelBuilder builder = provider.builderForAddress(host, port);
ManagedChannel channel = builder.intercept(new ClientAuthInterceptor(creds, Executors
            .newSingleThreadExecutor
                    ()))
            .build();

private static final List<String> OAUTH2_SCOPES =
        Arrays.asList("https://www.googleapis.com/auth/cloud-platform");

创建SpeechGrpc.SpeechStub:

SpeechGrpc.SpeechStub mSpeechClient = SpeechGrpc.newStub(channel);

感谢您的时间 :)

最佳答案 我报告了这个问题
in the forum.

出现此问题的原因是您将服务帐户凭据嵌入应用程序中.一段时间后,当内部刷新创建的令牌时,将抛出错误:

com.google.auth.oauth2.ServiceAccountCredentials.refreshAccessToken link

在生产中,您将从服务器提供访问令牌,因此能够实例化GoogleCredentials:

    final GoogleCredentials googleCredentials = new GoogleCredentials(accessToken) {
        @Override
        public AccessToken refreshAccessToken() throws IOException {
            return accessToken;
        }
    }.createScoped(OAUTH2_SCOPES);

这样可以防止抛出错误.
