httpurlconnection

I'm trying to modify the open source library of cloudinary so that I can listen to the progress of the upload of my photo. The library class contains a MultipartUtility java class that I modified to listen to the progress of the upload. The original code before modifications can be found on github: https://github.com/cloudinary/cloudinary_java/blob/master/cloudinary-android/src/main/java/com/cloudinary/android/MultipartUtility.java I literally modified it to resemble the code from another cloud service CloudFS that supports progress when uploading files / images etc: https://github.com/bitcasa

How come HttpURLConnection.getResponseCode() throws IOException even if the status is known? Caused by: java.io.IOException: Server returned HTTP response code: 412 for URL: <my url> It's not a problem of getting the response code because it is written in the exception message. I would expect to have an option to get the status code (even if it's not ~200) without getting an exception, so I'll be able to decide in my code what to do. Full stack trace: Caused by: java.io.IOException: Server returned HTTP response code: 412 for URL: <my url> at sun.net.www.protocol.http.HttpURLConnection

Which is better for API Level 9(Gingerbread) and why? Is there any benefit to use AndroidHttpClient over HttpUrlConnection? Any help or guidance will be well appreciated. Google doesn't recommend using AndroidHttpClient , only on very old Android versions. But as you can see in many questions on SO, HttpURLConnection is not easy to use. It's very low-level and doesn't have a comfortable interface. You have to know quite a lot how it's working internally and if you have luck, you get exceptions when you use it the wrong way. For that reason many libraries have been developed for Android

For my Android app I need to download a file from a site requiring login. It is not basic http authentication but rather form emulation. Being new to Android I really don't know how to get started, but in PHP it is easy with cUrl: // Set standard options curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE); curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1); curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7) Gecko/20040803 Firefox/0.9.3"); curl_setopt($ch, CURLOPT_HEADER, 0); curl_setopt($ch, CURLOPT_POST, 1); curl_setopt($ch, CURLOPT_COOKIEJAR, "somecookiejar");

I want to read a remote text file and show its content in a textview. I have written this below code, but it doesn't get any information from the text file. How can I find the reason of this problem or solve it? isn't there anything wrong in my code? private void readFile() { try { String path ="http://host.com/info.txt"; URL u = new URL(path); HttpURLConnection c = (HttpURLConnection) u.openConnection(); c.setRequestMethod("GET"); c.setDoOutput(true); c.connect(); InputStream in = c.getInputStream(); Log.e("value",in.toString()); AssetManager mngr=getAssets(); ByteArrayOutputStream bo = new

Is HttpUrlConnection thread safe? I.e. if I have an HttpConnection instance connected to a server and this instance is used by different threads (e.g.try to send a POST concurrently) how will this situation be handled by HttpUrlConnection? a) Will they send the POSTs serially, or b) the first thread sends the POST, gets the response and then the second thread will send the POST? If they send the POSTs serially, this means multiple active POSTs to the same tcp connection. Is this allowed? Can it be handled by a server? Thanks It does not say if it is or not in the docs.
