Android Question 'try' without 'catch' or 'finally'

[mohammad javad]

I'm creating a socket to connect to my server on port 80 but I,m facing this error in debuger

B4A Version: 9.80
Java Version: 11
Parsing code. (3.70s)
Building folders structure. (2.02s)
Compiling code. (6.22s)
Compiling layouts code. (0.02s)
Compiling debugger engine code. Error
B4A line: 50
End Sub
shell\src\b4a\example\networkphp_subs_0.java:100: error: 'try' without 'catch' or 'finally'
try {
^
1 error

my code is

Sub Activity_Create(FirstTime As Boolean)
    'Do not forget to load the layout file created with the visual designer. For example:
    'Activity.LoadLayout("Layout1")

    socket.Initialize("clienttoserver")
    socket.Connect("www.greenhomeiot.ir",port,10000)
    astream.Initialize(Me,"data")

End Sub

Sub clienttoserver_Connected (Successful As Boolean)
    
    
    If Successful Then
        Log("connected")
    Else
        ToastMessageShow("ارتباط با سرور برقرار نشد",True)
    End If
End Sub

Actually "B4A line: 50" in debugger error is line "End sub" for "Sub clienttoserver_Connected (Successful As Boolean)" in my code.
can anybody tell me what the problem is and how to solve it?
thanks

I'm not sure where the actual error comes from. Probably from different code.
However this code is wrong. Either switch to B4XPages or learn the activities life cycle: https://www.b4x.com/etp.html

Why aren't you using OkHttpUtils2?

why is this wrong?

I want to use https://www.b4x.com/android/forum/threads/37201/#content to make it possible my clients connect to each other by server via socket.
I actually use socket programming it has the last status which http doesn't provide simply
