To export your B4XPages project DO NOT use the menu "file - export as zip". Use:

I can only give 3 suggestions, only one of which concerns the B4XPages:

1 - the help. The source of the HTML page is shown, rather than the page itself.

2 - the operator touched and therefore current is not highlighted in the calculator.

3 - I would not give generic names to the B4XPages-classes nor to the object variables. In my opinion a good habit could be:
clsCalculator or, better, clspagCalculator - the class
pagCalculator - the object.


[StateManager is used well here. It is useful for keeping state between app "sessions" but it is not necessary to use it while using an app (advantage of B4XPages)]

LucaMs thanks for the feed back. I completely missed this one.
As it is I am surprised you were able to run the App, I tried from the Zip file I could not. I have tested the new upload and works from this end.

How much joy ?

However, I'm curious to see the source and I'll do it shortly.

I can say that the B4XPages are much easier to use than to manage the Activies and they really have many advantages.

I have only some doubts about the big difference between B4A, where it is possible (it is advisable) to use a single Activity but it is different with B4J and I believe also with B4i. I'll have to open a thread for this as this can be a problem in some cases.

Not quite sure which source you refer too

For the current state of the pages, for example the text contained in an EditText (B4XView) it is no longer necessary to use StateManager, it will not be lost if you send the app to background (if the app itself will not be killed by the OS).

To save the status for an eventual restart of the app, you could use the B4XPage_Background event

Well, I don't know your "question" (this one).

Anyway, I loaded your helpfile.html in a webview of a B4J-B4XPages project and it looks ok while in B4A it doesn't ?

Alternatively you can try to load the string from the file then use LoadHtml to show the html.
