Android Question [SOLVED] B4XPages in landscape but...

[LucaMs]

B4XPages project. I have some landscape pages but I need to add a chat. In addition to being ugly, in landscape, the keyboard and especially the "system input View" would cover the entire screen.

Using an additional Activity, for chat only, would be a big problem, because Main would not be active and would not receive data from my server.

The only complicated solution that comes to mind is to create a personal keypad (but it would not be easy to insert emojis) and the user would not like it.

Big issue!

Don't use an additional Activity, chat in a B4XPage and "move" the websocket to it?
Maybe yes but the ugliness of a chat in landscape and the problems of the input view that covers everything remain.

1. Don't so anything in the Main module.
2. The B4XPages classes are never paused.

I know those very well

???

If I added an Activty for the chat, having the connection to the server (websocket) in the B4XMainPage (which is in the Activity Main), when chat is open, Main-B4XMainPage is closed and does not receive data from the server.

No.

2. The B4XPages classes are never paused.

?

 

[LucaMs]

No.

?

Even when the Activity Main (with B4XMainPage and the others) is not active-open (while a second Activity is open)?

The main advantage of B4XPages is that they all are into a single Activity, right?

 

[LucaMs]

Even when the Activity Main (with B4XMainPage and the others) is not active-open (while a second Activity is open)?

Yes (tested; quickly and therefore not thoroughly).

 

[Erel]

The only edge case that you need to think of, is that there could be a case where the app is killed and is then started from the second activity. You can check whether B4XPages.IsInitialized returns True and if not, call StartActivity(Main).

Thanks, Erel.

I was convinced (?) that starting an Activity the current one was no longer active (in my case, the Main with B4XMainPage, which could no longer receive data from my server).

Doing a test, after you have denied this belief of mine, I have seen that actually despite having the second Activity in foreground, B4XMainPage and therefore the Main, continues to be active.

I noticed this log:

(activity is not paused)

is this relatively recent? Thanks to B4XPages? Or have I, now very old ?? , forgotten everything and had it always been so?

 

[Erel]

Thanks to B4XPages?

It is a unique feature of B4XPages. The hosting activity is never paused.

So my doubt was legitimate, I'm not completely stoned ?

Thanks again, Erel.
