Android Question Ping web without waiting

How to ping website without waiting for a response ?


I use ping as background service, sample code in Ping Service module :

    Dim SB As StringBuilder
    SB.Initialize
   
    PH.Shell("ping -c 1 www.google.com"),Null,SB,Null)
   
    If SB.ToString="" Then
        StatusPing="Failed"
    Else
        StatusPing="Success"
    End If

In Main module, i use this code to start Ping service :

        StartService(PingService)

The problem is when start Ping service, Main module is freezing because waiting response for Ping service.

Surely the whole point of Ping is to get a response..

What are you trying to achieve here?

Getting a response in 0ms?

You can use HttpUtils2. This way the request will be executed in the background and will not freeze the program.

See HttpUtils2 tutorial: http://www.b4x.com/search?query=HttpUtils2

A standard http request will be sent. Not a ping.

Dim job As HttpJob
job.Initialize("ping", Me)
job.Download("http://www.vdfb.de/b4a/ping.php")


Sub JobDone(job As HttpJob)
    If job.Success Then
      If job.JobName = "ping" Then
            Dim res As String
        res = job.GetString
            If res = "pong" Then
                ToastMessageShow("Website ONLINE", True)
            End If
        End If
  Else
      Log("Error: " & job.ErrorMessage)
  End If
  job.Release
End Sub

You can use the ping-script (http://www.vdfb.de/b4a/ping.php) in your project if you want
