httpurlconnection - Android HttpsUrlConnection eofexception

Question

I have a problem where my HttpsURLConnection will throw an EOFException when i try to read any input. The code works for some network calls, but fails on others. If i try and read anything from the connection, it fails with the aforementioned error.

Example:

urlConnect.getResponseCode() // will throw error
urlConnect.getResponseMessage() // will throw error
BufferedInputStream in = new BufferedInputStream(urlConnect.getInputStream()); //will throw error

Here is the stack trace for each:

getResponse:

Thank you for any help,

EDIT I found my answer:

This was not a well documented answer. It appears in some of the newer versions of android, there is a bug with recycled url connections. To fix this (although there may be some performance issues), I needed to add:

if (Build.VERSION.SDK != null
&& Build.VERSION.SDK_INT > 13) {
urlConnect.setRequestProperty("Connection", "close");
}

Thanks!

Someone requested I answer my own question instead of editing. So here is the answer again.
