Body
Several problems with your code: <ol> <li>I guess your code fails - You requesting dialog show but have no OnCreateDialog which returns dialog to show, so You getting :</li> </ol> 08-16 16:26:52.748: E/AndroidRuntime(905): Caused by: java.lang.NullPointerException 08-16 16:26:52.748: E/AndroidRuntime(905): at android.app.Dialog.(Dialog.java:141) ). You need to to override onCreateDialog() in your Activity class <pre><code>@Override protected Dialog onCreateDialog(int id) { ProgressDialog progress; progress = new ProgressDialog(this); progress.setMessage("Loading data, please wait"); return progress; } </code></pre> <ol start="2"> <li>To start showing dialog, use this code in ProgressTask.preExecute(): { int taskId=1; //just example showDialog(taskId); }</li> <li>To dismiss dialog - use dismissDialog(taskId) in ProgressTask.postExecute();</li> <li>HTTP connection in main stream will cause exception. You have to use ProgressTask.doInBackground() to perform http connections.</li> <li>You should not modify UI elements from .doInBackground. Modify listAdapter of Activity and other UI elements in .preExecute() and/or .postExecute() of AsyncTask. It's covered in Google tutorial for AsyncTask usage.</li> </ol> Complete code example covering all the mentioned issues I've provided here: <a href="https://stackoverflow.com/questions/4081317/android-synctask-not-showing-the-list-after-progressdialog/13862657#13862657">Android, synctask not showing the list after progressDialog</a>

Guidance

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.
