android - DialogFlow Android SDK需要grpc-okhttp，但添加它会导致Socket IO CLient崩溃

Question

环境细节
DialogFlow Android SDK v2.1.0的问题
重现步骤

我已经使用DialogFlow在Android应用中实现了聊天机器人。我使用gradle实现导入了DialogFlow sdk。

我崩溃了，说java.lang.NoSuchFieldError:类Lio / grpc / internal / GrpcUtil中没有Z类型的静态字段IS_RESTRICTED_APPENGINE

根据我在Google搜索中解决此问题的搜索结果，我必须添加io.grpc:grpc-okhttp sdk。因此，我添加了它，此问题已解决，但又出现了一个问题。

我的Android应用程序项目还具有Socket IO Client。当我初始化套接字客户端时，出现崩溃，提示没有虚拟方法callEngineGetConnection(Lcom / squareup / okhttp / Call;)Lcom / squareup / okhttp / Connection;在Lcom / squareup / okhttp / internal / Internal类中；

如果我删除grpc-okhttp，那么Socket工作正常。

代码示例
如果您想测试一下，此代码可以重现该问题
套接字初始化

val socket = IO.socket("URL_HERE")
socket.connect()

DialogFlow初始化

val stream = resources.openRawResource(R.raw.credentials)
val credentials = GoogleCredentials.fromStream(stream)
val projectId = (credentials as ServiceAccountCredentials).projectId

val settingsBuilder = SessionsSettings.newBuilder()
val sessionsSettings = settingsBuilder.setCredentialsProvider(FixedCredentialsProvider.create(credentials)).build()
val sessionsClient = SessionsClient.create(sessionsSettings) //This line causes the crash
val session = SessionName.of(projectId, UUID.randomUUID().toString())

这是我的build.gradle

以下任何其他信息
简而言之，如果未添加grpc，则对话框流崩溃。如果添加了grpc，则Socket崩溃。

升级到最新的SocketIO客户端。它将使用与gRPC不冲突的okhttp3 API。每当遇到此类问题时，也请考虑升级依赖项。
