android - 在 android 中聊天时 Quickblox Chat 连接断开

Question

我正在开发一个涉及 Quickblox 的安卓应用程序。我不断收到消息“聊天连接已断开”。阅读 logcat 后，这就是我得到的:

我找不到相同的解决方案。

Answer 1

套接字是您用来通过网络进行通信的工具(例如，连接到 Internet 上的服务器)。错误信息的意思是某个程序试图通过网络从远程计算机接收数据，但是一段时间没有接收到数据，所以程序停止等待接收数据。

这里是可以通过增加套接字超时来解决此问题的代码 fragment ，因为 Quickblox 中的默认 SocketTimeOut 是 30 秒。

QBChatService.ConfigurationBuilder chatServiceConfigurationBuilder = new QBChatService.ConfigurationBuilder();
chatServiceConfigurationBuilder.setSocketTimeout(180); //Sets chat socket's read timeout in seconds
chatServiceConfigurationBuilder.setKeepAlive(true); //Sets connection socket's keepAlive option.
QBChatService.setConfigurationBuilder(chatServiceConfigurationBuilder);
