    <p><strong>EDIT</strong></p> <p>This in combination with Nikolay Elenkov suggestion about using ScheduledThreadPoolExecutor provided a very nice solution.</p> <hr> <p>I found a solution that fits my purpose better than using a Service and BroadcastReceiver. I have no need to check for news/updates when the app is not running, so using a service would be overkill and just use more data than needed. I found that using Handlers was the way to go. Here is the implementation that works perfectly:</p> <p><strong>Avtivity:</strong></p> <pre><code>public class UpdateServiceActivity extends Activity implements OnClickListener { private Handler handlerTimer; private Runnable newsHandler; @Override public void onCreate( Bundle savedInstanceState ) { handlerTimer = new Handler(); newsHandler = new NewsHandler( handlerTimer, this ); handlerTimer.removeCallbacks( newsHandler ); } @Override protected void onPause() { handlerTimer.removeCallbacks( newsHandler ); super.onPause(); } @Override protected void onResume() { handlerTimer.postDelayed( newsHandler, 5000 ); super.onResume(); } } </code></pre> <p><strong>NewsHandler</strong></p> <pre><code>public class NewsHandler implements Runnable { private static final int THERE_IS_NEWS = 999; private Handler timerHandler; private Handler newsEventHandler; private Context context; public NewsHandler( Handler timerHandler, Context context ) { this.timerHandler = timerHandler; this.newsEventHandler = new NewsEventHandler(); this.context = context; } public void run() { Message msg = new Message(); msg.what = THERE_IS_NEWS; newsEventHandler.sendMessage( msg ); timerHandler.postDelayed( this, 5000 ); } private class NewsEventHandler extends Handler { @Override public void handleMessage( Message msg ) { if( msg.what == THERE_IS_NEWS ) Toast.makeText( context, "HandlerMessage recieved! There is news!", Toast.LENGTH_SHORT ).show(); } }; } </code></pre>

    1. COThis will run on the UI thread, so if you have to do actual network I/O, it will be a problem. If you only need this to work while the app is visible, you may look at `AsyncTask` or start a processing thread.

    2. COCould you provide a sample implementation that provides the same functionality? I considered using AsynTask, but I found that doing so did not fit that well into the Android framework (scheduling a specific task to run at a given interval, which should then post results on the UI). AsyncTask is good for one-time execution, but I need it to run as long as my Activity is visible (e.g. the task gets stopped in onPause and restarted in onResume).

    3. COYou can schedule your `NewsHandler` to run periodically using `ScheduledThreadPoolExecutor` and post messages to `NewsEventHandler` to update the UI (you won't need `postDelayed()`, but you'll need to start/stop the executor on pause/resume). Or, if want to do this using handlers, have it run on a background thread with something like `HandlerThread thread = new HandlerThread("HT"); Handler handlerTimer = new Handler(thread.getLooper());`

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.
