    <p>The ELAPSED_REALTIME approach could work I think, but strangly it is not for a small test app I created. Basically the test app is a widget and a IntentService. The widget only shows the current time, while the Intent Service gets the current time and sends a broadcast which the widget consumes in the onReceive() method and updates itself. The widget is of course a registered receiver for the custom broadcast action. In the onEnabled() method in the widget, I initialize the alarm for AlarmManager. Now some code:</p> <p><strong>Widget onEnabled():</strong></p> <pre><code>@Override public void onEnabled(Context c) { super.onEnabled(c); Intent intent = new Intent(c.getApplicationContext(), SimpleIntentService.class); PendingIntent intentExecuted = PendingIntent.getService(c.getApplicationContext(), 45451894, intent, PendingIntent.FLAG_UPDATE_CURRENT); AlarmManager alarmManager = (AlarmManager) c.getApplicationContext().getSystemService(Context.ALARM_SERVICE); alarmManager.setInexactRepeating(AlarmManager.ELAPSED_REALTIME, 0, 3000, intentExecuted); } </code></pre> <p><strong>Widget onReceive():</strong></p> <pre><code>@Override public void onReceive(Context context, Intent intent) { super.onReceive(context, intent); if (intent.getAction().equals(ACTION_RESP)) { AppWidgetManager appWidgetManager = AppWidgetManager.getInstance(context); ComponentName thisWidget = new ComponentName(context.getApplicationContext(), Widget.class); int[] allWidgetIds = appWidgetManager.getAppWidgetIds(thisWidget); for (int appWidgetId : allWidgetIds) { RemoteViews remoteViews = new RemoteViews(context.getApplicationContext().getPackageName(), R.layout.widget); String s = ""; if (intent.hasExtra("msg")) s = intent.getStringExtra("msg"); // Set the text remoteViews.setTextViewText(R.id.textView1, s); appWidgetManager.updateAppWidget(allWidgetIds, remoteViews); } } } </code></pre> <p><strong>SimpleIntentService onHandleIntent():</strong></p> <pre><code>@Override protected void onHandleIntent(Intent intent) { Log.w("TestService", "SimpleIntentService onHandleIntent called."); String msg = new Date().toGMTString(); Intent broadcastIntent = new Intent(); broadcastIntent.setAction(Widget.ACTION_RESP); broadcastIntent.addCategory(Intent.CATEGORY_DEFAULT); broadcastIntent.putExtra("msg", msg); sendBroadcast(broadcastIntent); } </code></pre> <p>So, I have tested this on my Nexus 4 running Android 4.2.1 and on an emulator with Android 4.0.4. In both cases the SimpleIntentService gets created and onHandleIntent() gets called every 3 seconds, even when I manually turn the display off. I have absolutely no idea why the AlarmManager still schedules the alarm, do you have?!</p> <p>Thank you!</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.
