Android Question B4X for connection check

[luke2012]

Hi all,
within my B4X (only mobile Android & iOS) app (that get data using REST API) I need to check if it is an internet connection before continue.

Searching the forum I found this interesting [B4X][B4XLib] by @LucaMs.
just to my knowledge, is it the only solution within the B4X framework to check the connection without having to write the code from scratch?

I think Erel recommends just trying the connection and if it fails just show some kind of message. i.e.: “there was some problem connecting to the source. Are you connected to internet?”

I m using this lib and it is very helpful without any problem. You can use google or other website to check it. I can say that checking with google.com is a little bit slow process to receive answer so use other webpage.

@José J. Aguilar and @pliroforikos thanks for your suggestions.
So I have to choose which is the best approach for my B4XPages app (Android & iOS).

basically, in my app, there are several places where this code is called:

    Dim j As HttpJob : j.Initialize("j", Me)
    j.Username = aUser
    j.Password = aPsw
    Private WSUrl As String = WSNodeURL & nid & WSFormat
    j.Download (WSUrl)
    
    Wait For (j) JobDone(j As HttpJob)
    If j.Success Then
        Private WSResponse As String = j.GetString2("UTF8")
    End If
    j.Release

So to prevent errors (ex. iOS Airplane mode) in my case I can handle this within else of "If j.Success Then", I guess.

so I have to then apply this across all occurrences of this code within my app, I guess.

    Wait For (j) JobDone(j As HttpJob)
    If j.Success Then
        Private WSResponse As String = j.GetString2("UTF8")
    else
        'msg 4 connection error
    End If

In my case, the problem is that the above code is within a non UI class (clsGlobals) so I can't do this:

    toast.Initialize(Root)
    toast.VerticalCenterPercentage = 50
    toast.Show($"there was some problem connecting to the source"$)

So in my case, maybe this speech is not implementable?
