[geckoview:fenix:m4] because we should fix this before Fenix MVP, but (I assume!) fixing this crash is not an urgent blocker because GV developers can use older Android emulator images.

Comment 2

:snorp reported that he doesn't see this crash and I can also run gv apps fine on my Pixel2, so this might be just a weirdness in either the Mac android emulator or my laptop.

Comment 3

[Chris Peterson [:cpeterson]]

Deferring to Fenix M5. This is not an urgent priority because Fenix MVP will be released before Android Q.

Comment 4

[Chris Peterson [:cpeterson]]

Demoting to priority [geckoview:fenix:p2] because Android Q support is not a Fenix MVP release blocker.

Comment 5

[Kevin Brosnan [Ex-Mozilla]]

Agi does building an aarch64 GV run?

Comment 6

[[ex-Mozilla] Agi Sferro | :agi]

Kevin sounds like your theory is correct: aarch64 doesn't crash while armv7 does crash on my Pixel 2 with Android Q.

Comment 7

[Kevin Brosnan [Ex-Mozilla]]

Going to dupe this to the bug that has more investigation.
