1. You should post the error message.
2. I've ran the code and didn't see any error.

2. Because i commented that line in B4X main page

B4X:

'Wait For (ShowSplashScreen) Complete (Unused As Boolean)

error will show up when you uncomment it .
1. Error is

java.lang.RuntimeException: Object should first be initialized (B4XView).

You are missing many things.

There is an example: [B4X] [B4XPages] Splash Screen
Carefully follow it.

I took it from that example. Problem is when i have another page ( page6 in my example ) and when I'm trying to send a text ( on page6 ) to the label ( on main page )

B4X:

lblHello.Text = Page6.txtUser.Text

app is not starting ( see a previous error ) . App is showing error because of this

B4X:

Wait For (ShowSplashScreen) Complete (Unused As Boolean)

Best Regards ,
Przemek

I followed. Still the same. Error is showing when it's trying to refer to that label on another page. Good thing now is that splash screen showing for few seconds before app crash

Wow. Amazing that you are still missing the manifest change.
Point #1 in the example.

It crashes because the Appear event is raised before the layout is loaded.
Change the code to:

B4X:

Private Sub B4XPage_Appear
    If lblHello.IsInitialized Then
        lblHello.Text = Page6.txtUser.Text
    End If
End Sub

Or better, delete it and set the label directly from page 6 when needed.

Now, that he helped you solve your long standing issue, you need to work on spelling his name correctly. Just kidding of course.

I don't mind. Really.

More important to pay attention to the instructions
