    <p>For those who don't know, there are two major Http client API's available for use in Android:</p> <ul> <li>Apache HTTP Client</li> <li>java.net HttpURLConnection</li> </ul> <p>A recent overview of both of these is given in this <a href="http://android-developers.blogspot.com/2011/09/androids-http-clients.html" rel="nofollow">Android Developers Blog post</a>.</p> <p>I've chosen to use the java.net implementation, because, quoting the blog: "<em>New applications should use HttpURLConnection; it is where we will be spending our energy going forward.</em>" Also, HttpURLConnection will connect using SSL automatically if the Url provided is Https. As I stated in the original post, I was looking for an interface within the API that would allow me to automatically handle authentication challenges, if necessary. I've found that the Authenticator class does what I want.</p> <p>Here is the code that I have so far, and it works: </p> <pre><code>URL Url = new URL(url); Authenticator.setDefault(new Authenticator () { protected PasswordAuthentication getPasswordAuthentication() { return (new PasswordAuthentication("username", "password".toCharArray())); } }); connection = (HttpURLConnection) Url.openConnection(); connection.setRequestProperty("Authorization", "Basic"); content = new BufferedInputStream(connection.getInputStream()); BufferedReader reader = new BufferedReader(new InputStreamReader(content)); String line; while ((line = reader.readLine()) != null) { stringBuilder.append(line); } </code></pre> <p>The key (for me) to getting the Authenticator's method to actually be called, was this line:</p> <pre><code>connection.setRequestProperty("Authorization", "Basic"); </code></pre> <p>Otherwise, the request would actually return a response of 200 (OK), and redirect me to a login page.</p> <p><strong>Next Step</strong>: From the <code>getPasswordAuthentication</code> method above, prompt the user for a username and password, and somehow return it. If you can help with this, post an answer!</p>

    1. COHeh; learn something new every day. I had read that java.net was considered obsolete, having been developed for JavaME, and that everybody should use the Apache client. I've only used java.net in situations where the Apache library was unavailable. I guess it's time to switch back.

    2. COEdward, I just came across a question you asked (http://stackoverflow.com/questions/6100989/java-how-to-launch-a-ui-dialog-from-another-thread-e-g-for-authenticator), and the answer you/Andrew provided seems to be somewhere along the lines of what I'm trying to do now. You said in a comment "I kind of wish Java had the message-passing facility of Android." Since we're talking about Android now, how would you recommend going about it?

    3. CONice work guys..I have a complicated iOS auth process and had no idea how to do it in Android. I'm surprised there aren't more upvotes for both of you. I have to store un/pw to pass an SSL and then pass a Windows Authentication challenge after that, so this post helps for this type of process.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
