Android Question custom view error during release build, not debug

[RichyK68]

Hi,

When I'm running and testing in Debug mode everything works fine. When I build to release I get this:

** Activity (review) Create, isFirst = true **

It is due to the custom view I am using on the layout.

What am I doing wrong?

Thanks,

Can you upload a project that demonstrates this issue?

Hi,

Sure thing! I just knocked this up in a couple of minutes. Works in debug, crashes in release.

Maybe I'm doing something wrong ...

The problem is here:

Public Sub DesignerCreateView (Base As Panel, Lbl As Label, Props As Map)
   mBase = Base
   Base.LoadLayout("MyCustomView")
       
End Sub

You cannot load a layout file while the current layout file is loaded. The solution is simple.
Change it to:

Public Sub DesignerCreateView (Base As Panel, Lbl As Label, Props As Map)
   mBase = Base
   Sleep(0)
   Base.LoadLayout("MyCustomView")
End Sub

This way the second layout will be loaded after the first one completed.

Hi Erel, thanks for the reply, which library would Sleep be in? I currently get:

B4A version: 6.31
Parsing code. Error
Error parsing program.
Error description: Undeclared variable 'sleep' is used before it was assigned any value.
Occurred on line: 23 (MyCustomView)
Sleep(0)

Sleep is an internal keyword added in v7.0. You can use CallSubDelayed instead and load the layout in that sub.
