“Unexpected end of file” implies that the remote server accepted and closed the connection without sending a response. It’s possible that the remote system is too busy to handle the request, or that there’s a network bug that randomly drops connections. It’s also possible there is a bug in the server: something in the request … Read more
The answer is, that HttpUrlConnection does not support digest. You therefore have to implement RFC2617 by yourself. You can use the following code as a baseline implementation: HTTP Digest Auth for Android. The steps involve (see RFC2617 for reference): If you get a 401 response, iterate over all WWW-Authenticate headers and parse them: Check if … Read more
Turned out this is a known bug in Android’s class implementation. Calling Connection.setRequestProperty( “Accept-Encoding”, “” ); before connecting can be used as workaround. https://code.google.com/p/android/issues/detail?id=24672
I’ve implemented my own idea. It’s actually pretty cool. I’ve created my own implementation of java.net.CookieManager which forwards all requests to the WebViews’ webkit android.webkit.CookieManager. This means no sync is required and HttpURLConnection uses the same cookie storage as the WebViews. Class WebkitCookieManagerProxy: import java.io.IOException; import java.net.CookieManager; import java.net.CookiePolicy; import java.net.CookieStore; import java.net.URI; import java.util.Arrays; … Read more
Unfortunately, native JSON support was delayed past Java 9. But for the sake of sportmanship here is plain Java 8 hacky solution using Nashorn JavaScript engine without any external dependency: String json = “{\”foo\”:1, \”bar\”:\”baz\”}”; ScriptEngine engine = new ScriptEngineManager().getEngineByName(“nashorn”); Object o = engine.eval(String.format(“JSON.parse(‘%s’)”, json)); Map<String, String> map = (Map<String, String>) o; System.out.println(Arrays.toString(map.entrySet().toArray())); // [foo=1, … Read more
Its’ taken me a few hours but I managed to build a custom cookie storage myself. You have to attach this by doing this: public class application extends Application { @Override public void onCreate() { super.onCreate(); CookieManager cmrCookieMan = new CookieManager(new MyCookieStore(this.objContext), CookiePolicy.ACCEPT_ALL); CookieHandler.setDefault(cmrCookieMan); } } Here’s the actual storage: /* * This is a … Read more
This used to work in the past, but it has been disabled as part of a security-fix. Apparently without a note in the changelog. There are even bugs like #7022056 for this at bugs.sun.com. There is a similar question for another header, where the answer goes more into the details, so I just link it … Read more
The connection pool used by HttpURLConnection when it is keeping connections alive is broken such that it tries to use connections that have been closed by the server. By default Android sets KeepAlive on all connections. System.setProperty(“http.keepAlive”, “false”); is a workaround that disables KeepAlive for all connections so then you avoid the bug in the … Read more
I found out the reason. First of all, to all who aren’t aware of what this error means (I sure wasn’t): This exception is thrown if the server replies with a 401. Very intuitive, considering that it was thrown in getResponseCode() (i.o.w. you are never able to check for 401s yourself, but have to catch … Read more
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: … Read more
