` 不是必现，但在一台Android手机上复现几率达90%，基本都是一样的问题，下载一部分就不下载了，然后就任务失败了。别的手机暂时没发现这个问题。 看了很多人的帖子，什么添加Header都没有用，issues里感觉都没人解决这个问题，基本都是说服务端问题，文件是在阿里云上的，文件地址 ，求大佬帮忙看看，该怎么处理。

[RocZhengPeng]

我也遇到了

[YuriTam]

有没有人解决了这个问题的

[jingzhanwu]

最后怎么解决的

[chailijun]

碰到同样的问题，资源放在阿里云OSS上，浏览器下载正常，用该下载库下载基本100%复现该问题，求解？？

[javakam]

应该是 okhttp 的问题 https://github.com/square/okhttp/issues/3715

[javakam]

我遇到的情况是Android模拟器无法访问到局域网域名问题, 需要给模拟器也设置hosts

[lixbandroid]

现在是不维护了吗？为啥没有反馈啊？后台收到一大堆的崩溃日志

[skyzhw]

遇到同样问题，经过测试发现，在华为系列手机+阿里云CDN+特定的Wifi网络下，这个问题出现的概率很高。并且和当时的用网情况也有关系。根据排查，发现华为系手机socket的ReceiveBufferSize默认值是2097152,三星系统默认值是1048576.猜测和这个参数的系统调优有关。把华为系socket的ReceiveBufferSize参数调整到49152以下，这个问题出现概率很低，几乎很难复现。遇到同类问题的也可以试试.核心代码：new OkHttpClient.Builder().socketFactory()，socket.setReceiveBufferSize(49152);

[v587jasonzou]

同样的问题，我们通过抓包发现，我们的源文件设置了no-cache，阿里检测到文件大于100mb就会概率连接断开，出现response contnet-length和body大小不一的问题
