[Popup v2][Android] Popup Closed/Opened events are triggered when app goes to background/foreground

[tranb3r]

With Popup v2, the Closed event of a Popup is triggered when the app goes into the background (e.g., when minimized or suspended).
After the app resumes, the Opened event is raised again.

This behavior does not seem to occur in Popup v1, where the popup remained open when the app was backgrounded.
The Closed event was only raised when the popup was actually dismissed by the user or via code.

Is this new behavior intentional in Popup v2, or is it a regression compared to v1?

I think intentional, because it's extending a Page and it now behaves like a page. This includes all the navigatedTo, navigatedFrom, appearing, dissapearing. You can also get some knowledge in this relevent answer.

Ok, this behavior is debatable, but fair enough.
However, how can you tell whether the popup was actually dismissed by the user or programmatically, versus being automatically closed when the app goes into the background (given that it simply reappears when the app resumes)?

Scenario:

1. The app opens a popup and waits for the user to enter a value.
2. If the user dismisses the popup or clicks a Cancel button, the popup closes and the app correctly interprets that the user has cancelled the action.
3. If the app goes to the background and then resumes, the popup is still visible — I would expect the app to continue waiting for user input as nothing has changed. However, when the app resumes, it behaves as if the popup has been dismissed or cancelled, even though it is still open.

I did not test this @tranb3r , can you confirm it is like this?

It is as simple as that :
Closed is called on app going to background.
So, how can you tell whether the popup was actually dismissed by the user or programmatically, versus being automatically closed?

I was mistaken @tranb3r. On our end, the event .Closed is not called when app is going into the background (Android). It is called when the Popup is closed. Can somebody else test it, so I will not make a mess here.

This sounds like a regression to me. I suspect it's difficult to confirm but do you know if the popup does actually close when the app is backgrounded?

[rokmeglic71]

When the app is only de-activated (backgrounded), the popup stays active, so when you come back to the same page after re-activiting the app, the popup is there. The close handler of the popup works normally.

If you close the app, meaning closing the entire screen and the app does not go to the background, then the popup is closed and the app starts at the init page.
