    <p>After reading lots of sample code into this matter, I'm trying to figure out the simplest way to achieve the following:</p> <p>I want to be able to schedule an Intent that calls back to my Alarm BroadcastReceiver, which in turn fires off my Service. However, I want to set up so that it calls said Intent twice a day and to only schedule the alarms if they haven't already been set (likewise for canceling the alarms).</p> <p>However, I am unsure if the following code is the correct way to set and cancel alarms.</p> <pre><code>//Static function for setting the alarm //My midday calendar object (cal1) ... //My evening calendar object (cal2) AlarmManager alarms = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE) Intent myIntent = new Intent(context, MyAlarmReceiver.class); PendingIntent firstCallIntent = PendingIntent.getBroadcast(context, FIRST_CALL_ID, myIntent, PendingIntent.FLAG_NO_CREATE); PendingIntent secondCallIntent= PendingIntent.getBroadcast(context, SECOND_CALL_ID, myIntent, PendingIntent.FLAG_NO_CREATE); if(firstCallIntent == null){ if(DEBUG){ Log.d(TAG, "Setting Midday Alarm"); } firstCallIntent = PendingIntent.getBroadcast(context, FIRST_CALL_ID, myIntent, 0); alarms.setInexactRepeating(AlarmManager.RTC_WAKEUP, cal1.getTimeInMillis(), AlarmManager.INTERVAL_DAY, firstCallIntent); } if(secondCallIntent == null){ if(DEBUG){ Log.d(TAG, "Setting Evening Alarm"); } secondCallIntent = PendingIntent.getBroadcast(context, SECOND_CALL_ID, myIntent, 0); alarms.setInexactRepeating(AlarmManager.RTC_WAKEUP, cal2.getTimeInMillis(), AlarmManager.INTERVAL_DAY, secondCallIntent); } //Static call to cancel the alarm. AlarmManager alarms = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE) Intent myIntent = new Intent(context, MyAlarmReceiver.class); PendingIntent firstCallIntent = PendingIntent.getBroadcast(context, FIRST_CALL_ID, myIntent, 0); alarms.cancel(firstCallIntent); firstCallIntent.cancel(); PendingIntent secondCallIntent = PendingIntent.getBroadcast(context, SECOND_CALL_ID, myIntent, 0); alarms.cancel(secondCallIntent); secondCallIntent.cancel(); </code></pre>

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.
