941038 - Shutdown and or session bustage on closing the browser while active hardware media in use

Status: RESOLVED WORKSFORME

(Firefox for Android Graveyard :: General, defect)

Description

[Aaron Train [:aaronmt]]

Currently when one swipes the browser off the application recents list in Android, some fault in browser shutdown or session restore happens.

Steps

i) http://mozilla.github.io/webrtc-landing/gum_test.html
ii) Share Video
iii) Swipe the browser off the application recents list
iv) Launch the browser

Expected: About:Home
Actual: http://mozilla.github.io/webrtc-landing/gum_test.html

Bonus: Console continues to spew camera messages despite it not being in use

Brian - How is this supposed to work? How does the webrtc notification foreground stuff effect it?

After bug 885783, swiping Fennec from the recent apps should immediately kill Fennec and remove any WebRTC notifications (explanation in https://bugzilla.mozilla.org/show_bug.cgi?id=885783#c22). Only active downloads should keep Fennec alive.

I thought this was just fixed in bug 932816. Aaron, does this mean bug 932816 still isn't fixed, or are these symptoms different?

We kill the notification, I just have no idea if the browser is cleanly shutdown here or what. It's trivial to reproduce. My console floods with [1] after I swipe the browser off the list, so I have no idea what's going on here.

WFM on my HTC One. Aaron, which phone are you using?

When you reopen the browser, is it loading from a cold state, triggering a session restore, and reloading the page? Or is it not being killed to begin with, and so the page is still open? If the former, we have a bug with session restore; if the latter, we have a bug with foreground notifications.

Also, would you mind posting a logcat when this all happens?

Oddly enough this now works for me when re-testing on Nightly and Aurora (29.0, 12/13). I am using an LG Nexus 4 (Android 4.4.2) today; when I launch the browser icon I am situated back on about:home instead of the previous page. When I visit History, I see the page listed under tabs from last time.

Here are some logs:

I'll re-open if I see this on another device.
