加载未完成时断网，之后一直报错[单例模式]

[Loyea]

使用的是getInstance()的模式

加载未完成时断网，此后无论加载什么都是先走完超时后由webview原生重新进行加载（似乎是），而且缓存功能也失效了

报的都是这同一个错误

加载未完成应该就没有缓存，超时后交给系统webview处理了，系统webview应该判断断网，处理速度也应该很快的

[Loyea]

问题是以后无论请求啥，网络状态也没问题，都会报这个错，这个库的功能就彻底失效了

[yale8848]

你意思，先联网，再断网，再联网，一直都会报这个错吗？断网后再联网应该能正常访问的，这个我都是测试过的。

@yale8848 对的。写了个简单的demo 我截了个视频: https://www.youtube.com/watch?v=bwWOz_Yn75A

我测试几个图片ok，youtub +vpn 按照你说的模式也ok；那麻烦你提供更多代码，以便分析问题

[Loyea]

就上面这点代码就能复现啊。。。。而且还是100%复现的 我视频里面就是这个 没别的代码了 布局就一个button和webview 我的视频不够详细么

[Loyea]

另外没有使用代理

[Loyea]

用非单例模式先规避了，还是很好用的。这个bug我也看不懂原因，麻烦你了

[yale8848]

你用真机再试试，看还有没有问题
