title: Pending intent with ONE_SHOT flag
body: <p>Currently I've got this code:</p>
  
  <pre><code>public static void setupAlarm(Context context) {
          Intent myIntent = new Intent(context, Receiver.class);
  
          PendingIntent pendingIntent = PendingIntent.getBroadcast(context,
                  0, myIntent, PendingIntent.FLAG_NO_CREATE);
          if (pendingIntent != null) {
              return;
          } else {
              pendingIntent = PendingIntent.getBroadcast(context, PENDING_INTENT_RETRY, myIntent,
                      PendingIntent.FLAG_ONE_SHOT);
          }
  
          AlarmManager alarmManager = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
          Calendar calendar = Calendar.getInstance();
          calendar.setTimeInMillis(System.currentTimeMillis());
          calendar.add(Calendar.MINUTE, 2);
          alarmManager.set(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), pendingIntent);
      }
  </code></pre>
  
  <p>What I want is to use pending intent one time and wait for the fire. If in the meantime someone asks for a new alarm, if the alarm exist I don't want to setup anything. Now my question: after the first alarm, the pending intent is deleted due to the ONE_SHOT flag, but can I create the pending intent again or not?</p>
