Android的 - HttpURLConnection的不打烊。最终结果以SocketException [英] Android - HttpUrlConnection is not closing. Eventually results to SocketException

问题描述

我遇到了一些问题，运行杰利贝恩（4.1 - 4.3）中的HttpURLConnection中的设备，其中连接不关闭，结果SocketException异常打开的文件过多执行的若干倍。

I am encountering some problems with the HttpUrlConnection in devices running Jellybean (4.1 - 4.3) wherein connections are not closed and results to a SocketException "Too many open files" after executing a number of times.

我叫HttpUrlConnection.disconnect（）和我关闭所有的InputStream，OutputStream中，读者和作家finally块。

I do call HttpUrlConnection.disconnect() and am closing all the Inputstream, Outputstream, Reader and Writers in a finally block.

将亚行外壳和执行的netstat 显示所有的应用程序创建的连接被留在CLOSE_WAIT状态。

Going to adb shell and executing a netstat shows all the connections created by the application are left in CLOSE_WAIT state.

InputStream inputStream = httpUrlConnection.getInputStream();

// After calling inputStream.read() then the problem occurs. I think the 
// inputstream doesn't get closed even after calling close in a finally block. 
// The InputStream is a ChunkedInputStream if that helps.

我尝试了2.3.3，4.0.3和4.4上运行的其他设备并没有遇到这个问题。

I have tried other devices running on 2.3.3, 4.0.3 and 4.4 and did not encounter this issue.

有另一种方式，我可以手动关闭连接？

Is there another way that I can manually close the connections?

推荐答案

我终于找到了解决办法。看来，杰利贝恩正在对保持活动连接的问题。我只是说连接=关闭我的请求头，现在一切正常。做一个netstat的，我看到，现在连接被关闭，我不再让SocketException由于打开的文件太多。

I finally found a workaround. It seems that Jellybean is having an issue on "Keep-Alive" connections. I just added Connection=Close to my request header and now all is working. Doing a netstat, I see that the connections are now being closed and I no longer get the SocketException due to "Too many open files".
