Android Question [Solved] Can't call CallSubDelayed2 with Variable?

incendio · Oct 12, 2016

Hi guys,

I have this code that raised an error

B4X:

Sub Test(RowId)
    CallSubDelayed2(CallFrom, SubToCall,RowId)
    Activity.Finish   
End Sub

Change the code to this

B4X:

Sub Test(RowId)
    CallSubDelayed2(CallFrom, "MySub",RowId)
    Activity.Finish  
End Sub

Fix the error. It is a bug or a normal behavior?

It seems to be a normal behaviour that you dont post the error you got.

incendio · Oct 12, 2016

It seems to be a normal behavior that the error if not the issue here, so no need to post it, just simple question should it raised an error or not.

if SubToCall contains the string
MySub
then it should work.

incendio · Oct 12, 2016

I have tried it, it didn't work.

The error is "Sub mysub doesn't found."

mysub in the log is in lower capital, actual Sub name is MySub.

try

B4X:

Sub Test(RowId)
    CallSubDelayed2(CallFrom, "mysub",RowId)
    Activity.Finish 
End Sub

This will work, but this

B4X:

Sub Test(RowId)
    Private SubToCall as String
    SubToCall = "mysub"
    CallSubDelayed2(CallFrom, SubToCall ,RowId)
    Activity.Finish
End Sub

Doesn't works
java.lang.Exception: Sub mysub was not found.

Hace you tried with smart string literal. ---> $""${SubtoCall}""$?

DonManfred · Oct 12, 2016

what is CallFrom? It should be an activity object... based on https://www.b4x.com/android/forum/t...teract-between-activities-and-services.18691/

LucaMs · Oct 12, 2016

Your second code should work.
Check if you have a module named CallFrom (CallFrom? Module to call!) and that this module has a routine named mysub.

Here are the code to call a sub in other activity

B4X:

Sub bbBatch_Clicked
    Private m As Map
    m.Initialize
    m.Put("CallFrom",Me)
    m.Put("SubToCall","MySub")
    CallSubDelayed2(ModSearchFrmN, "ShowData",m)
End Sub

And here are the codes from module ModSearchFrmN

B4X:

Sub Globals
  Private CallFrom As Object
   Private SubToCall As String
End Sub

Sub ShowData(Params As Map)
   CallFrom    = Params.Get("CallFrom")
   SubToCall    = Params.Get("SubToCall")
End Sub

Sub Test(RowId As Int)
    CallSubDelayed2(CallFrom, SubToCall,RowId) 'this is the error line
    Activity.Finish 
End Sub

There is no module named CallFrom

CallSubDelayed2(CallFrom, $""${SubToCall}""$,RowId) -> didn't work either.

java.lang.Exception: Sub "mysub" was not found.

With "module" I meant: Activity module or Code module or Service module.

See the CallSubDelayed2 parameters; the first one must be the "module" which contains the routine to call.

There is no activity / service module with that name, CallFrom.
CallFrom is just an Object variable.

My 50cts : the obfuscation ? Adding an underscore in the sub's name ?

You were right

Change the codes into like this solved the problem

B4X:

Sub bbBatch_Clicked
    Private m As Map
    m.Initialize
    m.Put("CallFrom",Me)
    m.Put("SubToCall","My_Sub") 'change Sub Name from MySub to My_Sub
    CallSubDelayed2(ModSearchFrmN, "ShowData",m)
End Sub

I saw but if that is the solution, your first post was wrong (this is what I meant with my post, #16)
