Thanks for the heads up Baku!
What is the advantage of using the syncAPI over mozAlarms?
Thanks,

Hi all,
I just landed RequestSync API, an API for b2g only that allows
apps to schedule tasks.
Here the webIDL:
https://hg.mozilla.org/integration/mozilla-inbound/file/f60d4ad64070/dom/webidl/RequestSyncScheduler.webidl
A simple example is this:
navigator.sync.register('foobar', { minInterval: 2,
oneShot: true,
data: 42,
wifiOnly: false,
wakeUpPage: location.href
}).then(
function() {
ok(true, "navigator.sync.register() oneShot done");
...
}, genericError);
navigator.mozSetMessageHandler('request-sync', function(e) {
ok(true, "One event has been received!");
is (e.task, "foobar");
...
});
The params are:
1. minInterval - in seconds. It can happen that this operation
will be scheduled with a bigger interval.
2. oneShot - true/false, similar to setInterval/setTimeout.
3. data: whatever you want to pass to the message handler.
4. wifiOnly: if true, the task will not scheduled if wifi is not
active
5. wakeUpPage: the page that will receive the system message.
We also have a 'setting' API accessible only if the app has the
'requestsync-manager' permission.
This is the webIDL:
https://hg.mozilla.org/integration/mozilla-inbound/file/f60d4ad64070/dom/webidl/RequestSyncManager.webidl
With this API the settings app can overwrite the policy and the
minInterval of any task of any app:
navigator.syncManager.registrations().then(
function(results) {
...
results[0].setPolicy("wifiOnly", 123 /* minInterval */);
});
