Hey
Please see below code

B4X:

'
1: Sub Class_Globals
2:  
3: End Sub
4:
5: Public Sub Initialize
6:
7: End Sub
8:
9: Sub JobDone(Job As HttpJob)
10:
11:   if job.success then
12:      log("success")
13:   else
14:      'get current activity that use this class
15:      'call method with name "ShowError"
16:   end if
17:
18: End Sub

In line 14 and 15 i need detect current activity and call method in relate activity
I dont want to use CallSub or CallSubDelay
Only need call method with current activity

B4X:

Sub Class_Globals
 Private mCallback As Object
End Sub

Public Sub Initialize(Callback As Object)
 mCallback = Callback
End Sub

Sub JobDone
 '...
 CallSubDelayed(mCallback, "JobDone_Error")
End Sub

Activity code:

B4X:

MyClassIntance.Initialize(Me)

Activity code:

MyClassIntance.Initialize(Me)

I knew it but i need to call method with last opened activity
maybe?

Where is this class initialized? Starter service?

Service or Activity and maybe in Starter Service

Sounds strange. Create a single instance in the starter service.
Set the current activity with this code:

B4X:

Sub Activity_Resume
 Starter.YourClassInstance.mCallback = Me
End Sub

Put this code in each of the activities.
