Android Question Advantages and disadvantages between "CallSubDelayed" and "Wait For"

[vecino]

Hi, both ways work apparently the same, but what are the pros and cons of using one or the other option.
Thank you.

Sub timgv1_Click(X As Int, Y As Int)
    CallSubDelayed3("","ControlarUbicacion",X,Y)
End Sub

Sub ControlarUbicacion( X As Int, Y As Int )
  ' Do something here.
End Sub

Sub timgv1_Click(X As Int, Y As Int)
    Wait For (ControlarUbicacion(X,Y)) complete (oRes As Object)
End Sub

Sub ControlarUbicacion( X As Int, Y As Int ) As ResumableSub
  ' Do something here.
  Return Null
End Sub

They are very different mechanisms. With CallSubDelayed execution continues, and the called method is added to a "queue" that will be performed after the current sub exits (see https://www.b4x.com/android/forum/t...teract-between-activities-and-services.18691/)

With WaitFor, the sub exits and stop processing with that statement. Execution will resume once the WaitFor condition is met (see https://www.b4x.com/android/forum/threads/b4x-resumable-subs-sleep-wait-for.78601/)

So, to summarize, I understand that CallSubDelayed continues to execute the following instructions. And WaitFor obviously waits for them to execute and then continues.
Thank you very much.
