刚刚第一次尝试使用我们的 APK 进行 ARC。它开始正常但无法连接到我们的后端服务器：

SocketException：setsockopt 失败：EINVAL（无效参数）

2015-04-07 下载的当前 Chrome 和 ARC。

堆栈跟踪显示它尝试设置不支持的 KeepAlive 套接字选项失败（比该指针）。

添加SocketConfig socket = SocketConfig.custom().setSoKeepAlive(false).build();到 HttpClient 并没有帮助，就像HttpClientConnectionOperator总是调用一样sock.setKeepAlive(socketConfig.isSoKeepAlive());，在我看来，即使使用false...调用，调用也会崩溃

谢谢，干杯，汤姆。

这里有两个问题：

隐含地，您是在询问有关基于错误的 setsockopt 支持。是的，ARC 支持 setsockopt 调用的子集。您可以在我们的开源存储库中查看我们的 posix 翻译层以及支持哪些标志：https ://chromium.googlesource.com/arc/arc/+/release-41.4410.244.0/src/posix_translation/socket_stream.cc# 98（这是针对当前的 ARC 41 版本）。不幸的是，根据您的调用堆栈，您正在尝试设置 SO_KEEPALIVE，目前不支持。如果您想给它加星标，这里有一个跟踪问题，但不太可能很快实施：https ://code.google.com/p/chromium/issues/detail?id=384940

关于 HTTPS/SSL，我们从外部得到了一些关于这方面的报告，但这些报告大多是模糊的。一些 SSL 确实有效，因此尚不清楚为什么有些人会遇到问题。如果您可以使用突出显示 HTTPS/SSL 问题的源创建一个小的复制 APK，您可以提交错误以帮助隔离此问题。
