Android Question Annoying black/gray screen before the app start

[Mike1970]

Hi everyone, I finished my app, but there is an imperfection that annoy me..
Before the app actually start there is a black/gray screen.
The problem is that in the main Activity_Create is veeeery simple, same for Starter Service

it is just:

Sub Activity_Create(FirstTime as Boolean)
    Activity.Loadlayout("layout")
    Sleep(1500)

    If (File.ReadString(---,---) == "---") Then
        StartActivity(Conf)
    Else
        StartActivity(Home)
    End If
  
    Activity.Finish
End Sub

Thanks in advance

Change the activity theme color: https://www.b4x.com/android/forum/threads/theme-colors.87716/#content

If the layout is large then you can split it into multiple files, load the first one and later load the others.

Sorry Erel, i didn't understand what you mean .

My ideal goal is to show immediatly the background with the logo.

What do you mean by "split into multiple file"? the layout is composed by only 4 images, set in the designer.

I drastically reduced the time of startup, removing a webview i forgot there unused, and by compressing ALL the images i use in the app using this website.
I changed the theme, as you suggested.

Now instead of gray, it appears white, for a fraction of time.
If someone knows how to simulate something like "launchscreen" of iOS, this would be ideal.

why do you have sleep() after you load your layout?
does the layout file include the logo? do you want to show first the logo then after 1.5 sec start an activity?

    If (File.ReadString(---,---) == "---") Then

Did you write "==" intentionally?

 

[Mike1970]

Did you write "==" intentionally?

yes

 

[raphael75]

yes

I didn't know that it was possible to use "==" in B4A/B4X

This is not a valid syntax. As it happens the parser ignores it but it is possible that in the future it will be rejected.
