Android HttpsUrlConnection eofexception

android, eofexception, httpurlconnection

Solution

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

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");
}

Problem

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: ``` 03-14 09:49:18.547: W/System.err(6270): java.io.EOFException 03-14 09:49:18.547: W/System.err(6270): at libcore.io.Streams.readAsciiLine(Streams.java:203) 03-14 09:49:18.547: W/System.err(6270): at libcore.net.http.HttpEngine.readResponseHeaders(HttpEngine.java:573) 03-14 09:49:18.547: W/System.err(6270): at libcore.net.http.HttpEngine.readResponse(HttpEngine.java:821) 03-14 09:49:18.547: W/System.err(6270): at libcore.net.http.HttpURLConnectionImpl.getResponse(HttpURLConnectionImpl.java:283) 03-14 09:49:18.547: W/System.err(6270): at libcore.net.http.HttpURLConnectionImpl.getResponseCode(HttpURLConnectionImpl.java:495) 03-14 09:49:18.547: W/System.err(6270): at libcore.net.http.HttpsURLConnectionImpl.getResponseCode(HttpsURLConnectionImpl.java:134) ``` BufferedInputStream: ``` 03-14 09:39:14.077: W/System.err(5935): java.io.EOFException 03-14 09:39:14.077: W/System.err(5935): at libcore.io.Streams.readAsciiLine(Streams.java:203) 03-14 09:39:14.077: W/System.err(5935): at libcore.net.http.HttpEngine.readResponseHeaders(HttpEngine.java:573) 03-14 09:39:14.077: W/System.err(5935): at libcore.net.http.HttpEngine.readResponse(HttpEngine.java:821) 03-14 09:39:14.077: W/System.err(5935): at libcore.net.http.HttpURLConnectionImpl.getResponse(HttpURLConnectionImpl.java:283) 03-14 09:50:46.547: W/System.err(6476): at libcore.net.http.HttpURLConnectionImpl.getInputStream(HttpURLConnectionImpl.java:177) 03-14 09:50:46.547: W/System.err(6476): at libcore.net.http.HttpsURLConnectionImpl.getInputStream(HttpsURLConnectionImpl.java:271) ``` Thank you for any help, Rick EDIT I found my answer: This was not a well documented answer.
