Converting .bas file to .b4xlib is just as easy as add the file as a .zip file.

To save data, there are also many alternatives such as KVS and File.WriteMap.

    Log(GetType(v))

    Log(GetType(v))

I'm sorry my terrible English. I don't know : Are there types of views in activity? How to code in Do while Loop of each type of views?

you can do it like this:

    For Each v As View In Activity.GetAllViewsRecursive
        Log(GetType(v))
    Next

this will loop through all the views in your activity.
you can also do it for a single panel that holds many views.

Log(GetType(v))

Can also check for types directly eg:

For Each v As View In Activity.GetAllViewsRecursive
    If v is Button Then
        Log("Press that Button! 👇")
    Else If v Is CheckBox Then
        Log("Tick that Box! ✔️")
    Else If v Is TextField Or v Is TextArea Then
        Log("Write that Text! ✍️")
    Else
        Log("I don't recognise " & GetType(v))
    End If[
Next

In example,he used that code strategy,but each view I must code all of views for supportted. (My English can't expain my thinking).

You don't need to store the state of all views. If you use B4XPages, you don't even need to store anything.
Before B4XPages era, maybe you only want to store the value entered in a text field when you navigate to other activity and load this value when you return but this is no longer a thing now.
