[已回复] MobileIMSDK的android端当手机黑屏后，再次唤醒手机的异常信息解读

UDPUtils.send 中报错了，虽然最后是能链接上，但是总感觉不爽，
是什么原因导致的呢？ 各位大佬，看看呢

这样的异常不用理会，因为每个厂商的ROOM里，对于熄屏省电的理解和策略都不同，所以到底是什么具体的方式让你的socket处于无法工作状态都不重要（或者说你是无法预测到底是什么方式，因为厂商太多了，方法也太多了），重要的是能在亮屏后依靠自动治愈算法恢复就行了。

你如果非得纠结这个异常的原因，那基本上最 大的可能就是厂商通过省电策略禁了你的socket后，它已处于一个非正常的状态（即脏现场），后绪的操作当然会报乱七八糟与此有关的异常了。总之，算法有治愈能力，可以恢复就不存在任何问题，属于算法可以掌控的范围内的非正常情况。
