Android Question Show Next page in B4X Pages

RishiKumar2210 said:

Hi. I am new to B4X Pages. I created a new project using B4X Pages and I added a standard page named "Sample". I have to open page 2 immediately after B4XMainPage is displayed. But It Shows An Error. Here is My Code

B4X:

Private Sub B4XPage_Created (Root1 As B4XView)
'    Root = Root1
'    Root.LoadLayout("MainPage")
    page1.Initialize
    B4XPages.AddPage("page1", page1)
    B4XPages.ShowPage("page1")
End Sub

Thanks @LucaMs. Error Has Been Solved. But No Views are displaying. Only a Blank Screen is displayed.

Better to start a new thread for a new question.
