httpurlconnection

I am newbie to android and this is my first project on android. I am struggling with "authentication" problem for more than a day. I tried several options but none of them worked. Basically, I want to call a REST API and get response. I am sure that there is no problem in API as I use the same one in another iOS application. I pass authorization header but still authentication no found message is shown. I found few question on stackoverflow related to this, but some of them did not work and some does not make sense to me. I get status code 401 . I know this means either no authentication

I have some typical codes which used HttpURLConnection to get a file with an URL. They worked fine in android 1.x and 2.x. But failed in Android 4.1! I searched on the web but found little similar information. Would anybody please help to investigate this issue? private String mURLStr; private HttpURLConnection mHttpConnection; ... url = new URL(mURLStr); ... mHttpConnection = (HttpURLConnection) url.openConnection(); mHttpConnection.setDoOutput(true); mHttpConnection.setRequestMethod("GET"); ... InputStream is = mHttpConnection.getInputStream(); The getInputStream method throws an exception:

I'm trying to write out to URLConnection#getOutputStream , however, no data is actually sent until I call URLConnection#getInputStream . Even if I set URLConnnection#doInput to false, it still will not send. Does anyone know why this is? There's nothing in the API documentation that describes this. Java API Documentation on URLConnection: http://download.oracle.com/javase/6/docs/api/java/net/URLConnection.html Java's Tutorial on Reading from and Writing to a URLConnection: http://download.oracle.com/javase/tutorial/networking/urls/readingWriting.html import java.io.IOException; import java.io

I am doing basic http auth with the HttpURLConnection object in Java. URL urlUse = new URL(url); HttpURLConnection conn = null; conn = (HttpURLConnection) urlUse.openConnection(); conn.setRequestMethod("GET"); conn.setRequestProperty("Content-length", "0"); conn.setUseCaches(false); conn.setAllowUserInteraction(false); conn.setConnectTimeout(timeout); conn.setReadTimeout(timeout); conn.connect(); if(conn.getResponseCode()==201 || conn.getResponseCode()==200) { success = true; } I am expecting a JSON object, or string data in the format of a valid JSON object, or HTML with simple plain text

I am using HTTPURLConnection to connect to a web service. I know how to use HTTPURLConnection but I want to understand how it works. Basically, I want to know the following: On which point does HTTPURLConnection try to establish a connection to the given URL? On which point can I know that I was able to successfully establish a connection? Are establishing a connection and sending the actual request done in one step/method call? What method is it? Can you explain the function of getOutputStream and getInputStream in layman's term? I notice that when the server I'm trying to connect to is down,

I'm relatively new to android development. I'm developing an android application where i'm sending request to web server and parsing json objects. Frequently i'm getting java.net.SocketTimeoutException: Connection timed out exception while communicating with the server. Some times it will work perfectly without any problem. I know this same question has been asked in SO many times. But still i didn't get any satisfying solution to this problem. I'm posting my logcat and app-server communication code below. public JSONObject RequestWithHttpUrlConn(String _url, String param){ HttpURLConnection
