    <p>I use this code to activate periodic alarms via broadcast receiver:</p> <pre><code>public class UpdateReceiver extends BroadcastReceiver { public static final String LOG_TAG = "camerawatch.alarmactivator"; public static final String ACTION = "de.pribluda.android.camerawatch.UPDATE_ALARM"; public static void activate(Context context) { AlarmManager alarmService = (AlarmManager)context.getSystemService(Context.ALARM_SERVICE); Intent intent = new Intent(ACTION); PendingIntent pendingIntent = PendingIntent.getBroadcast(context, 0, intent, PendingIntent.FLAG_NO_CREATE); Log.d(LOG_TAG, "pending intent: " + pendingIntent); // if no intent there, schedule it ASAP if (pendingIntent == null) { pendingIntent = PendingIntent.getBroadcast(context, 0, intent, 0); // schedule new alarm in 15 minutes alarmService.setInexactRepeating(AlarmManager.RTC, System.currentTimeMillis(),300000, pendingIntent); Log.d(LOG_TAG, "scheduled intent: " + pendingIntent); } } @Override public void onReceive(Context context, Intent intent) { Log.d(LOG_TAG, "received intent: " + intent); CameraWidgetProvider.displayCurrentState(context); } } </code></pre> <p>Note, that activation is done in static method, so I can call it from almost everywhere. I schedule alarm if and only there is no such pending intent. As for context - it is available virtually everywhere - In activity ( it is context itself ) in broadcast receiver (serice method parameter) etc. </p> <p>PS: broadcast receiver is preferable to service, because it does not run all the time. When service method returns, it is stopped and application is potentially disposed ( unles it does something else, but mostly it stays around in background). This provides better battery life</p>

    1. COit works... thanks.... On addition is I added name to the intent and I am filtering the intent with the name... so no need to specify the alarm receiver in intent. Thanks :D

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.
