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.

Status{code=UNAUTHENTICATED, description=null, cause=java.io.IOException: Error getting access token for service account: }

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。让我们命名为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(在Samsung GT-P5110(Android 4.2.2)上)后出现此错误:

  1. 开始活动A - >按Button启动活动B.
  2. //第一次一切都好。我从服务器收到结果并显示此信息。

    1. 关闭活动B(按后退按钮或调用onBackPressed或完成)。

    2. 按按钮启动活动B.

    3. //在这一刻我得到错误,如上所示。

      我在联想A1000(API 5.0.1)和小米Mi4c(5.0.1)之后遇到此错误:

      1. 开始活动A - >按下按钮以启动活动B.

      2. 关闭活动B(按后退按钮或调用onBackPressed或完成)。

      3. 按按钮启动活动B.

      4. //一切都很好

        1. 关闭活动B(按后退按钮或调用onBackPressed或完成)。

        2. 最小化应用

        3. 5-6分钟后,返回活动A.

        4. 开始活动B.

        5. //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后会出现错误。

          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)。它没有解决问题。

          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);

我报告了此问题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,如下所示:

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

这样可以防止错误被抛出。
