Android Question Gap before main LoadLayout

rraswisak · Nov 30, 2018

Hi all,

Every time i run b4a app there always gap (blank white screen with app title) before main layout was loaded.

this is Activity_Create look like;

B4X:

Sub Activity_Create(FirstTime As Boolean)
   Activity.LoadLayout("Main")
   pnlMenu.Left = pnlMenu.Width * -1
   pnlMenu.Visible = True
   CreateCustomListMenu(True)
   ShowDashboard(False)
End Sub

is there any way to to solve this problem ?

thank you

1. Test it on a real device in release mode. It might be fast enough.

2. Make sure not to do too much work when the program starts. You can use Sleep(50) after you load the layout and then do more work.

3. Disable the layout animation by setting the duration to 0 in the layout file.

4. Use a full screen theme: https://www.b4x.com/android/forum/threads/full-screen-theme.93892/#content
