Status: RESOLVED INCOMPLETE

(Firefox for Android Graveyard :: Custom Tabs, defect, P2)

Description

[Marcia Knous [:marcia]]

This bug was filed from the Socorro interface and is
report bp-0a7b05a2-8cd7-4704-8a9b-45e160190103.
=============================================================

Seen while looking at crash stats for Fennec release: https://bit.ly/2Qp3XN6. Seems to be rising a bit according to crash stats. According to the stack it looks to have something to do with custom tabs:

java.lang.IllegalArgumentException: removeChild: container=Task=82 is not a child of container=Stack=1 current parent={stackId=1001 tasks=[{taskId=82 appTokens=[AppWindowToken{52c7e83 token=Token{63fda01 ActivityRecord{98093e8 u0 org.mozilla.firefox/org.mozilla.gecko.customtabs.CustomTabsActivity t82}}}, AppWindowToken{c5e3d95 token=Token{2fe27b4 ActivityRecord{2438c87 u0 de.axelspringer.yana.zeropage/de.axelspringer.yana.activities.HomeActivity t82}}}, AppWindowToken{a31b160 token=Token{e45c163 ActivityRecord{10dd392 u0 org.mozilla.firefox/.App t82}}}] mdr=false}]}

Eitan, can you please take a look at this? It's rising in frequency on release.

Comment 2

[Eitan Isaacson [:eeejay]]

Handing this over to the GeckoView team.

Interesting. This is not a new crash signature, but the volume doubled around October 5 and then started climbing further starting in mid-December, perhaps after Fennec 64 was released (December 11).

Comment 4

[Chris Peterson [:cpeterson]]

James says this is a Fennec bug. There is no GeckoView code involved. Fennec is receiving an Intent and trying to launch a custom tab.

Making sure this is on Susheel's radar.

Liz sorry how do we get this on our P1 list? I am still not clear on that, sorry.

Comment 7

[Liz Henry (:lizzard) (relman/hg->git project)]

It's on there -

[Ryan VanderMeulen [:RyanVM]]

Not going to make 65.0 at this point, but I'd still consider it for a dot release assuming the frequency on release 65 ends up being similar to what it was for 64.

[Marcia Knous [:marcia]]

In early 65 data this crash is showing up, but we won't know the full scope until we go out wider. I do see it on 67 but in very small volume.

Stalled crash with almost 5000 crashes on 68 release. Some of the top crashing phones are Lava, https://www.lavamobiles.com/.

Since the bug is closed, the stalled keyword is now meaningless.
