EMConnectionEventHandler class

~english The connection event handler.

For the occasion of onDisconnected during unstable network condition, you don't need to reconnect manually, the chat SDK will handle it automatically.

Note: We recommend not to update UI based on those methods, because this method is called on worker thread. If you update UI in those methods, other UI errors might be invoked. Also do not insert heavy computation work here, which might invoke other listeners to handle this connection event.

Adds connection event handler:

  EMClient.getInstance.addConnectionEventHandler(UNIQUE_HANDLER_ID, EMConnectionEventHandler());

Remove a connection event handler:

  EMClient.getInstance.removeConnectionEventHandler(UNIQUE_HANDLER_ID);

~end

~chinese 服务器连接监听类。

对于不稳定网络条件下的onDisconnected情况，您不需要手动重新连接， SDK会自动处理。

添加 connection event handler:

  EMClient.getInstance.addConnectionEventHandler(UNIQUE_HANDLER_ID, EMConnectionEventHandler());

移除 connection event handler:

  EMClient.getInstance.removeConnectionEventHandler(UNIQUE_HANDLER_ID);

~end
