    <blockquote><b>Update: </b> Found the answer myself, see below :-)</blockquote> <p>Hi, </p> <p>I'am currently coding an android app that submits stuff in the background using HTTP Post and AsyncTask. I use the <a href="http://developer.android.com/reference/org/apache/http/client/package-summary.html" rel="noreferrer">org.apache.http.client</a> Package for this. I based my code on <a href="http://www.androidsnippets.org/snippets/36/" rel="noreferrer">this example</a>.</p> <p>Basically, my code looks like this: </p> <pre><code>public void postData() { // Create a new HttpClient and Post Header HttpClient httpclient = new DefaultHttpClient(); HttpPost httppost = new HttpPost("http://192.168.1.137:8880/form"); try { List&lt;NameValuePair&gt; nameValuePairs = new ArrayList&lt;NameValuePair&gt;(2); nameValuePairs.add(new BasicNameValuePair("id", "12345")); nameValuePairs.add(new BasicNameValuePair("stringdata", "AndDev is Cool!")); httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs)); // Execute HTTP Post Request HttpResponse response = httpclient.execute(httppost); } catch (ClientProtocolException e) { Log.e(TAG,e.toString()); } catch (IOException e) { Log.e(TAG,e.toString()); } } </code></pre> <p>The problem is that the <b>httpclient.execute(..) line takes around 1.5 to 3 seconds</b>, and I do not understand why. Just requesting a page with HTTP Get takes around 80 ms or so, so the problem doesn't seem to be the network latency itself.</p> <p>The problem doesn't seem to be on the server side either, I have also tried POSTing data to <a href="http://www.disney.com/" rel="noreferrer">http://www.disney.com/</a> with similarly slow results. And Firebug shows 1 ms response time when POSTing data to my server locally.</p> <p>This happens on the Emulator and with my Nexus One (both with Android 2.2).</p> <p>If you want to look at the complete code, I've put it on <a href="http://github.com/pableu/http-post-example/blob/master/src/com/gaga/project/newA.java" rel="noreferrer">GitHub</a>.</p> <p>It's just a dummy program to do HTTP Post in the background using AsyncTask on the push of a button. It's my first Android app, and my first java code for a long time. And incidentially, also my first question on Stackoverflow ;-)</p> <p>Any ideas why httpclient.execute(httppost) takes so long? </p>

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.
