Android Question Timer is Async ?

[Waldemar Lima]

hello guys,
i have a question about the "stopwatches", i need to create 100 thousand counters every 10 seconds to be activated asynchronously, if i use the algorithm below will i have any future problems? or do I need to use the "Threading" library?

algorithm :

Sub Process_Globals
    Public srvr As Server
    Private threading As Thread 'Need i use this ?
    Type TStopWatch (Identificador As String, cronometro As Timer)
    Dim stopwatch(99) As TStopWatch
End Sub

Sub AppStart (Args() As String)
    srvr.Initialize("srvr")
    srvr.Port = 80
    
    srvr.AddWebSocket("/appserver", "AppServer")
    srvr.AddHandler("/teste", "testes", False)
    DB.Initialize
    DB.Sync
    ServerManager.Initialize
    srvr.Start
    Log("Server Running on Port [80].")
    Log("AppServer Initialized on Port [80/appserver].")
    Log("JdbcConnectionPool Inintialized on [localhost:3306]")

    For i = 0 To stopwatch.Length-1

        stopwatch(i).Initialize
        stopwatch(i).Identificador = "identificador = "&i
        stopwatch(i).cronometro.Initialize("cronometro",1000)
        stopwatch(i).cronometro.Enabled = True

    Next

    StartMessageLoop
End Sub

'Return true to allow the default exceptions handler to handle the uncaught exception.
Sub Application_Error (Error As Exception, StackTrace As String) As Boolean
    Log("Error = "&Error)
    Log("StackTrace = "&StackTrace)
    Return True
End Sub

Sub cronometro_Tick
    
    'Log("sender = "&Sender)
    
    For i = 0 To stopwatch.Length-1
        
        If (stopwatch(i).cronometro = Sender) Then
            
            Log(stopwatch(i).Identificador & " # at " &DateTime.Time(DateTime.Now))
            Exit
            
        End If
        
    Next
    
End Sub

my fear is that there will be some inconsistency in the timers ...
is it stable?

Why not create a single timer and do 100,000 actions in the tick event?

The Tick event is raised on the main thread. It will only be raised when the main thread is free to process the message queue.

The Threading library is almost never the solution. You cannot create 100k threads.

thanks by you answer !

let's say that each connection on the Jserver, will be a new timer ....
