1087484 - [Window Management] Going to card view right after opening the camera app leads to a non functional shutter button

Status: RESOLVED DUPLICATE of bug 1087475

(Firefox OS Graveyard :: Gaia::System::Window Mgmt, defect)

Description

[KTucker [:KTucker][Inactive 3/4/2016]]

Description:
If the user opens the camera app, goes into card view immediately and goes back into the camera app, the shutter button will not function. Instead, the focus circles will keep appearing behind the button when tapped.

Repro Steps:
1)  Updated Flame to Build ID: 20141022001201
2)  Open the camera app and immediately hold down the home button to enter card view.
3)  Tap on the camera app to go back into it from card view. 
4)  Tap on the shutter button to take a picture.

Actual:
The camera focus circles will appear behind the shutter button every time the user taps on the shutter button instead of taking a picture.

Expected:
The camera takes a picture when the shutter button is pressed.

This issue also occurs on the Flame 2.2(319mb)(KK)(Full Flash)

The camera button will not function correctly after opening the camera app, going into card view immediately and then going back into camera. Focus circles will appear behind the shutter button when tapped.

I cannot reproduce this issue on the Flame 2.0(319mb)(KK)(Full Flash) because a different issue occurs.

The user will encounter a black screen when they open the camera app,goes into card view and then goes back into the camera app.

Broken functionality.

I cant reproduce this exactly. My first attempt with browser, settings and FM radio apps running I launched camera (ok'd the location prompt), long-tapped home button to show task manager, tap camera card and the camera app shows loading spinner and stuck there. On the 2nd attempt, all worked as expected. 

2.1 changed what happens when task-manager/cards-view shows: In <= 2.0 we used to open and switch the active app to be the homescreen. In 2.1 we close the active app, but do *not* open the homescreen. My hunch is this bug is linked to that.

Marking as a duplicate of Bug 1087475 since there is already ongoing investigation happening there.

I just want to make sure that my bug was clear. 

The camera viewfinder shows as expected for me when encountering my issue. The camera "Focus" circles are appearing behind the shutter button when the user taps on it. This is very timing specific. You have to tap on the camera icon and then immediately hold the home button to enter card view and then tap on the camera card to go back into camera. I was able to reproduce this 100% on today's Flame 2.1 build.

The other issue this has been duped to is the infinite blue "spinner" icon that stays on the screen when the viewfinder is not loaded at all. 

Just making a note to myself here to watch this issue in case the fix for bug 1087475 does not resolve my issue.

OK yeah I was just able to reproduce this also, by waiting until the shutter button appears (fraction of a second) before long-tapping home. They do both seem like symptoms of the same problem though - Camera is still initializing when it is closed by task manager. Lets watch this space (or bug 1087475)

Sounds good. Thank you Sam.
