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
URLConnection is only lazily executed whenever you call any of the get methods. Add the following to your code to actually execute the HTTP request and obtain the servlet response body. InputStream response = servletConnection.getInputStream(); See also: How to use java.net.URLConnection to fire and handle HTTP requests?
This should do the trick: URL url = new URL(yourUrlHere); Proxy proxy = new Proxy(Proxy.Type.DIRECT, new InetSocketAddress( InetAddress.getByAddress( new byte[]{your, ip, interface, here}), yourTcpPortHere)); URLConnection conn = url.openConnection(proxy); And you are done. Dont forget to handle exceptions nicely and off course change the values to suit your scenario. Ah and I omitted the import statements
This is how I do it, input = connection.getInputStream(); byte[] buffer = new byte[4096]; int n; OutputStream output = new FileOutputStream( file ); while ((n = input.read(buffer)) != -1) { output.write(buffer, 0, n); } output.close();
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
Try this: import java.net.HttpURLConnection; URL url = new URL(“http://www.myurl.com/sample.xml”); HttpURLConnection huc = (HttpURLConnection) url.openConnection(); HttpURLConnection.setFollowRedirects(false); huc.setConnectTimeout(15 * 1000); huc.setRequestMethod(“GET”); huc.setRequestProperty(“User-Agent”, “Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.9.1.2) Gecko/20090729 Firefox/3.5.2 (.NET CLR 3.5.30729)”); huc.connect(); InputStream input = huc.getInputStream(); OR import org.jsoup.nodes.Document; Document doc = null; try { doc = Jsoup.connect(“http://www.myurl.com/sample.xml”).get(); } catch (Exception e) { … Read more
Google has silently deprecated Apache HTTP client usage since Gingerbread: http://android-developers.blogspot.com/2011/09/androids-http-clients.html. And while they didn’t mark it with deprecated annotation, they suggest you to use HttpURLConnection for new applications as: it is where we [Google] will be spending our energy going forward. Personally I don’t like that decision and would rather stick to HttpClient 4.1+, … Read more
The response to my HTTP request returned with a status code 404, which resulted in a FileNotFoundException when I called getInputStream(). I still wanted to read the response body, so I had to use a different method: HttpURLConnection#getErrorStream(). Here’s a JavaDoc snippet of getErrorStream(): Returns the error stream if the connection failed but the server … Read more
Connection timeouts (assuming a local network and several client machines) typically result from a) some kind of firewall on the way that simply eats the packets without telling the sender things like “No Route to host” b) packet loss due to wrong network configuration or line overload c) too many requests overloading the server d) … Read more
Try: connection.setRequestProperty(“Range”, “bytes=” + fcheck.length() + “-“); Lowercase the range specifier per the spec. Also, if your partial file was 500 bytes, that means your byte range that you have is 0-499, and you want 500+.
