1807328 - Opening homescreen shortcuts takes noticeably longer than opening the app icon

Status: NEW

(Firefox for Android :: Performance, defect)

Description

[Chris Peterson [:cpeterson]]

From github: https://github.com/mozilla-mobile/fenix/issues/20558.

Steps to reproduce

• Add a homescreen shortcut
• Stop the app
• Launch the app via the app icon, note the time
• Hit the app switcher button and swipe closed the app
• Launch the app via the homescreen shortcut

Expected behavior

Both app launches take an equal amount of time

Actual behavior

Launching the homescreen icon takes longer. Here's a video: device-2021-07-28-124653.mp4.zip

Notes:

• the video is of a debug build: the delay will be shorter and possibly negligible in release variants
• iirc, VIEW intents take longer to get to the first frame than MAIN intents. This may be that issue, as opposed to an issue specifically with homescreen shortcuts

Device information

• Android device: P2
• Fenix version: e2af42a49768fc91423e5e872ca18c222463718b with my local async nav graph changes (PR #20176)
