Android Question "Wait for" not working in Return Subs

[Scantech]

Not sure if its a bug or not allowed?

Sub KeyPressWorkaround(KeyCode As Int) As Boolean
   
    Msgbox2Async("Test", "Test", "OK", "Cancel", "", Null, True)
    Wait For Msgbox_Result(Result As Int)
   
End Sub

It is not allowed. Move the actions that are based on the returned result to this sub after the wait for.

This is not a bug. You need to understand how the code flow goes and you will see why it is not possible to return a value.

If you want to wait for a resumable sub to complete: https://www.b4x.com/android/forum/threads/b4x-resumable-subs-sleep-wait-for.78601/page-2#post-499130
