1352099 - [PWA] Web Apps don't always have a title and icon in the task switcher entry

Status: VERIFIED FIXED

(Firefox for Android Graveyard :: Web Apps (PWAs), defect, P1)

Description

[Oana Horvath [:ohorvath]]

Attachment: ft - webapp task.png

Device:  LG G4 (Android 5.1) & Huawei Honor 8 (Android 6.0)
Build: Nightly 55.0a2 (2017-03-30);

Steps to reproduce:
1. Install a web app like: Financial Times (ft.com), or pokedex.org.
2. Open the web app.
3. Open the recent apps tray and check the task's title and icon.

Expected result:
Each web app should have a title & icon from the app's manifest.

Actual result:
Web apps tasks don't always have an icon and title. See screenshots attached.

notes: These two app examples initially had shown the correct icon and title, but while testing, I've found that they stopped working correctly and started showing only a generic "Web App" title and the Nightly icon. Can not determine an exact cause, I've reset Nightly and re-installed the web apps, with the same results.

I have seen this occasionally, will investigate

I am seeing this more often when I am using multiple webapps, if I only have 1 it works fine, but if I am constantly opening new ones, possibly a probably with webappindexer and reusing activities

Comment 4

[Dale Harvey (:daleharvey)]

ok found it, the background activity is being killed and during onCreate for some reason getIntent().getStringExtra is not returning anything

Comment 5

[Dale Harvey (:daleharvey)]

Ah I can see how the saveInstanceState is being used in other activities now

Attachment: Ensure manifest can be read on resume

I based this patch on top of https://bugzilla.mozilla.org/show_bug.cgi?id=1352726, got rid of having both loadManifest + updateFromManifest since that seemed unnecessary.

Verified as fixed on Nightly 55 (2017-04-05).
Devices:
- Motorola Nexus 6 (Android 7.0)
- LG G4 (Android 5.1)
- LG G4 (Android 6.0)

Note: on Huawei Honor 8 (Android 6.0), Xiaomi Mi Pad 2 (Android 5.1), Huawei MediaPad M2 (Android 5.1.1) the tasks still don't have a title and icon, just the generic "WebApp" name and the Nightly icon. These all have the EMUI system.

Forgot to mention here that the web apps behave the same on Chrome on these devices: without custom icon and title. 
I will file a new bug if it's possible to solve this.
