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。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:
//第一次一切都好。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)。
按按钮启动活动B.
//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:
开始活动A - >按下按钮以启动活动B.
关闭活动B(按后退按钮或调用onBackPressed或完成)。
按按钮启动活动B.
//一切都很好
关闭活动B(按后退按钮或调用onBackPressed或完成)。
最小化应用
5-6分钟后,返回活动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);

谢谢你的时间:)
答案 0 :(得分:1)
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。
