    <p>A few things... </p> <ol> <li><code>onEnabled</code> in an AppWidgetProvider is only called once when the first appwidget is added (that's when this AppWidgetProvider becomes "enabled"). Notice that onEnabled doesn't give you an <code>appWidgetId</code> - it's not a callback associated with a particular instance of an app widget on the home screen.</li> <li>You are calling <code>getStringExtra(AppWidgetManager.EXTRA_APPWIDGET_ID)</code> on an Intent you've just created. I think you meant to call <code>putExtra(AppWidgetManager.EXTRA_APPWIDGET_ID, appWidgetId)</code>. However, as mentioned above, this won't work either since you aren't given an id in <code>onEnabled()</code>.</li> </ol> <p>If you want to set an alarm that is associated to each appwidget instance on the home screen, you need to do some extra work.</p> <ol> <li>When you finish configuring an app widget, store its <code>appWidgetId</code> in SharedPreferences (you could use the key "appwidgetid_##" to store a boolean value, for instance).</li> <li>When <code>onUpdate()</code> is called and you are iterating over the <code>appWidgetIds</code> array, check each <code>appWidgetId</code> in SharedPreferences first. If the check passes, you know the user has configured that appWidget and you can create and set your alarm for it; otherwise, <code>continue</code> to the next <code>appWidgetId</code>.</li> <li>When setting the alarm, note that <code>Intent</code>s must be unique when creating <code>PendingIntent</code>s, otherwise you'll get a <code>PendingIntent</code> that reuses or overwrites the old one (depending on which flag you specify as the last argument to the <code>PendingIntent</code> call). Since extras are not considered when checking for uniqueness, see the code at the bottom for how to make it unique.</li> <li>In <code>onDelete()</code>, cancel the alarm for that appwidget. Make sure you construct the PendingIntent the exact same way. You can also remove the <code>appWidgetId</code> from SharedPreferences here.</li> </ol> <p>To make the intent unique:</p> <pre><code>Intent intent = new Intent(context, AlarmManagerBroadcastReceiver.class); intent.putExtra(AppWidgetManager.EXTRA_APPWIDGET_ID, appWIdgetId); // IMPORTANT! intent.setData(Uri.parse(intent.toUri(Intent.URI_INTENT_SCHEME))); // Note the FLAG_UPDATE_CURRENT PendingIntent pi = PendingIntent.getBroadcast(context, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT); AlarmManager am = ... am.setInexactRepeating(...); </code></pre>

    1. COThanks for replying, now my problem is that onUpdate is called before the configure activity finishes, and so the alarm can never being started...

    2. COIs it not calling `onUpdate()` again after configuration is complete? I suppose you could force the `onUpdate()` yourself by broadcasting an Intent with the `AppWidgetManager.ACTION_APPWIDGET_UPDATE` action and the `appWidgetId` as an extra. Or write a public static method to update the appwidget. Your `onUpdate()` method can call it, and so can your configuration activity. That way either one will start the alarms (`onUpdate()` will start it after device reboot, for instance).

    3. COI tried to call sendBroadcast(resultValue), but nothing happens, while with the static method when onReceive() is called if for example i've two widgets, they are both updated with the same data. Maybe there is something wrong with the context? In my static method StartAlarm(Context context, int widgetId), i use the configure activity context...

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.
