Android retrofit＋rxjava + okhttp 框架无网络的情况启动app崩溃

[louislrt]

软件采用retrofit＋rxjava + okhttp 框架实现网络通信，在启动时会崩溃，我已经查到崩溃原因是未能连接到服务器->SocketExceptionjava.net.ConnectException: Failed to connect to /101.200.217.254:8001。而且我在RequestListener中已经对错误有过记录（虽然没有进一步的操作），但是为什么还会一起崩溃。请大神指教

部分报错信息如下：

谢谢，我看了不是这个问题，我解决了。 参考的是https://stackoverflow.com/questions/43140321/why-retrofit-client-crashes-when-theres-no-network-connection 是个很蠢的问题，但是原理不是很懂，我在处理时重载Requestlistener里的onError就可以了，不知道为什么，但是确实好用，其他页面不重载也没问题，只有MainActivity里会引起崩溃
