    <p>I'm working on an android app that has to send and receive information from a 3rd party server. I'm not experienced at this at all, so bear with me if I give too much/too little/not the right kind of information at first.</p> <p>The API that was provided to send information has the format </p> <pre><code>https://methodurl.com/username=user&amp;password=pass&amp;key=key&amp;info=infotosend </code></pre> <p>When I put this URL into my desktops browser, it returns a string, which I'm also trying to get. At least, I'm assuming all it returns is a string, since if I look at the page source, there is just a string, such as "200 OK" or "401 Unauthorized".</p> <p>The code I'm using is what I can glean from the web what I'm supposed to use. Unfortunately, for all I know, I'm writing code to do something very different than what I want. I've never written code to interact with a server before, so this is all new to me.</p> <p>Here's my code:</p> <pre><code>TextView urlView = (TextView)findViewById(R.id.url_view); HttpClient client = new DefaultHttpClient(); HttpGet request = new HttpGet(siteToSubmit); ResponseHandler&lt;String&gt; responseHandler = new BasicResponseHandler(); try { String serverResponse = client.execute(request, responseHandler); urlView.setText(serverResponse); } catch (ClientProtocolException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } </code></pre> <p>Logcat in eclipse (when app is running on the emulator) is</p> <pre><code>java.net.UnknownHostException </code></pre> <p>The way I understand the code to be working is I'm creating a client that will execute on a url (like would happen when I hit enter in the URL bar on a browser), a request for that client to execute on, and a handler to receive the response from the server, which is set to be recieved as a string. I am then trying to set that string as the text in a TextView to verify that I am getting the proper response. Right now, I just get the log error, and urlView does not change. Any ideas why? Am I understanding the process correctly?</p> <p>Thanks!</p>

    2. COWell, I feel dumb. Nope, I didn't add the permission. This is also my first android app. Thanks! Can't seem to select your answer though, not sure why. Worked perfectly once I did.

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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
