Re: [b2g] Can't use mozAlarms API

2014-04-15 Thread Chris Mills 
I wrote a guide to setting alarms and then handling them using Notification API:

https://developer.mozilla.org/en-US/Apps/Build/Control_the_display/Using_Alarms_to_notify_users

This makes the point clear, I think. But I agree that it should be mentioned 
more explicitly in the reference docs.

 If this code is running in the system app, you are getting the list of alarms 
 added by the system app and not the clock.
 
 I think there seems to be confusion with what Alarms means. The Alarms API is 
 not for the 'wake me up every morning at 6' alarm the user adds in the clock, 
 but a set time in the future when the app would like to be woken up by the 
 system to do some task. So alarms are timers to 'start up me (the email app) 
 every 30 min so I can sync the user's email'. The Clock app uses the mozAlarm 
 API to implement the corresponding 'wake up a human' alarm. I hope this is 
 clear now.

 Hi there,
 
 I am trying to use the example given in 
 
 https://developer.mozilla.org/en-US/docs/Web/API/MozAlarmsManager.getAll 
 
 for one of my bugs, and it seems that it returns a different id everytime I 
 try to get alarm.id  and returns the current time in alarm.date.toString().

Could you paste example code of what your script is doing. If you are using the 
result of add(), it will be a new ID every time.
 
 Also, this link https://wiki.mozilla.org/WebAPI/AlarmAPI says No, the 
 getAll(...) only returns the alarms scheduled by the application.   If it 
 only returns the alarms added by the app itself, then what would be the 
 correct procedure to get the Alarm from the clock app. Will I have to use 
 alarmdb.js to retrieve them?

Apps are bound by the same-origin policy, just like normal web pages. Which 
means you cannot access anything the clock app is doing from another app. If 
you really need to get the list of alarms added by the clock app, you'll have 
to add Inter-App Communication API support to the clock, get it landed in Gaia 
(with a requisite justification of strong enough use cases for this feature) 
and then have your app talk to clock over IAC.

Nikhil

Thanks Nikhil for the reply. What I am doing is trying to get a list of
alarms in the system app. This is the code that I am using wrapped in a
function.

var request = navigator.mozAlarms.getAll();

request.onsuccess = function () {
  console.log('operation successful:' + this.result.length + 'alarms pending');

  this.result.forEach(function (alarm) {
console.log(alarm.id + ' : ' + alarm.date.toString() + ' : ' +
alarm.respectTimezone);
  });}

request.onerror = function () {
  console.log('operation failed: ' + this.error);}
