The data connection on woodduck doesn't work currently. This problem stops me from completing the reproducing procedure. Need 1109392 to be fixed first.

Hi Reporter, We cannot repo this issue on our side. Can you try repo the issue with Mozilla Gaia/Gecko? Thanks! User build image link is: http://pan.baidu.com/s/1hqnDBtM Access code: 9c9u unzip password: erT14moz

Dear YiFan, Can you help to verify the STR provided per comment 10 can reproduce this issue? Thanks!
Yes, will work on it shortly.
Without applying step 4, the usage app will be successfully launched once the 'webapps-launch' event is received in gaia. When usage app gets killed, gaia doesn't receive the event. Need gecko support on this one.
Hi Shawn, Could you please help to check the problem? Thanks!
I probably missed something here. Will check first.
Just a correction: the event that launches the usage app is 'open-app' not 'webapps-launch'. Tried reading gecko code but not being able to do much help here. Seems gaia has nothing to do with this issue. Please feel free to ni me if the assumption is wrong.

Hi Alive: May we have your comment on this bug first? Thanks!! Shawn
Flags: needinfo?(sku) → needinfo?(alive)
I believe this is a general notification issue - if an app had fired a notification and then being killed, the onclick callback will be reset so it will not launch itself. NI michael to confirm.

(In reply to Alive Kuo [:alive][NEEDINFO!] from comment #19) > I believe this is a general notification issue - if an app had fired a > notification and then being killed, the onclick callback will be reset so it > will not launch itself. NI michael to confirm. Cost control uses the shared/js/notification_helper object, which in 2.0 used the old desktop mozNotification API. I'm no expert of this API, but I believe it works like the new notification API in that when an app gets killed (either manually or through LMK) an existing notification click will fire a system message that will wake the app. Cost Control handles that system message here  in v2.0. We should check if we ever get that system message. If we don't we should check Gecko here  to see why it is not firing that system message after finding there is no live callback. 1.) https://github.com/mozilla-b2g/gaia/blob/71c64c4a914c8d4fb1e217b2a081fbc258e34622/apps/costcontrol/js/app.js#L288 2.) http://hg.mozilla.org/releases/mozilla-b2g32_v2_0/file/c6fd5db59e0e/b2g/components/AlertsService.js#l138
Since we've spent time on this issue, it deserve to be triaged.

Is there have any progress?
I'm investigating AlertsService.js and found that calling listener.observer.observe in ln:133 will cause an exception when following the STR. Need more time to trace notification source. I'm new in debugging Gecko source so please feel free to suggest possible causes, thanks!

Need more time to trace notification source. I'm new in debugging > Gecko source so please feel free to suggest possible causes, thanks! Hi Yifan. That exception is expected when the the app is not running. We should then catch that exception and then on ln:139 we will use the "system message" mechanism to wake the app and pass it the notification details. If that works properly, we should see that system message show up in the cost control app here . Do we ever see that system message in cost control? 1.) https://github.com/mozilla-b2g/gaia/blob/71c64c4a914c8d4fb1e217b2a081fbc258e34622/apps/costcontrol/js/app.js#L280
Thank you Michael! Found that the system message handler has never executed either the costcontrol app is launched normally or unsuccessfully in https://github.com/mozilla-b2g/gaia/blob/71c64c4a914c8d4fb1e217b2a081fbc258e34622/apps/costcontrol/js/app.js#L280 . Please see the attached log for more details. The log recorded a successful attempt and a failed one.
It seems the system message handler in the costcontrol app is never used? The view change in costcontrol seems to be all handled by the activity handler. I'll trace the activity part next.
Correction for the 'system message handler' above, it should be the system message handler for notification. The activity handler should be the system message handler for activity.

Tried it on mozilla-central, v2.2 and v2.1, gaia + gecko. All branches are affected.
Update: Communicate to partner will not fix in 2.0M. Will try fix in the future.
In https://dxr.mozilla.org/mozilla-central/source/dom/notification/DesktopNotification.h#159 mNotification is a nullptr when it fails. Keep tracing the cause.
1. Discovered that when a notification popped with costcontrol app off, the DesktopNotification instance will be deleted. https://dxr.mozilla.org/mozilla-central/source/dom/notification/DesktopNotification.h?from=desktopnotification.h&case=true#172 Here the Line DesktopNotification* mNotification; sould be nsRefPtr<DesktopNotification> mNotification; 2. After 1. fixed, when a notification popped with costcontrol app off, the system app will get an 'open-app' event to launch the costcontrol app in the background. But right after the app launched, the system app will receive a 'mozbrowserclose' event which in turn close the costcontrol app. I'm still working on why this happens. 3. When a notification popped with costcontrol app on, manually close the costcontrol app and then click the notification won't open the costcontrol app. Will look into this after 2. Here's the line that fails to launch the app without warning: https://dxr.mozilla.org/mozilla-central/source/dom/notification/DesktopNotification.h?from=desktopnotification.h&case=true#161
Yifan, thank you for your investigation. Since we are no longer fixing this issue for 2.0, we no longer need to worry about DesktopNotification.cpp. In 2.2+, cost control app uses the new Notification API , which means we use the Notification.cpp instead of DesktopNotification.cpp. And since we have the same problem in 2.2, it means it is for a different reason. Unfortunately, it seems you will need to do the same investigation from comment 32, but with the Notification.cpp code path. 1.) https://github.com/mozilla-b2g/gaia/blob/b09d45e0c28be573a0d95696c9df3e1d69ac0294/shared/js/notification_helper.js#L43
[Blocking Requested - why for this release]: Continue investigating in next release.
Any update here?
Couldn't be reproduced on foxfooding phone.
