Main / Backgroundtask Problem

[DennisW]

Hey guys,

Im coming from iOS developing in XCode...

Now I would like to write my first Android App and found this realy nice Software...

But I got an important question, because I got a little problem.

My code goes like this:

Sub HTTPClient1_ResponseSuccess (Response As HttpResponse, TaskId As Int)
   Response.GetAsynchronously("Response", File.OpenOutput(File.DirInternalCache, "temp.txt", False), True, TaskId)
End Sub

Sub Response_StreamFinish (Success As Boolean, TaskId As Int)
    If Success Then
      Dim TR As TextReader
      TR.Initialize(File.OpenInput(File.DirInternalCache, "temp.txt"))
      Result = TR.ReadAll
 
      Dim components() As String
      components = Regex.Split("B", Result)
   
      If Result.Length <> 0 Then
         Dim i As Int
         For i = 0 To components.Length -1
            Dim parts() As String
            parts = Regex.Split("S", components(i))

            Phone1.Send(parts(0),parts(1))
         Next
      End If
   
      If HTTPClient1.Execute(HTTPRequest1, 1) = False Then Return
      Label1.Text = "Weiterleitung AKTIV!"
   End If
End Sub

In short words, Im receiving numbers and messages from my webserver (CSV "B" and "S" seperator), and I would like to send a sms to each number/message pair.

If I take the output to a listview, everything is fine. If I take the Output to my PhoneSMS (Phone1) object, it creates the following error:

"NetworkOnMainThreadException"

I gues it appears because I tried to send a sms from a background task.

But how do I call a Main Task with B4A?

I know it in XCode, its [self performSelectorOnMainThread:...]; but how do I do it in Basic4Android?

I would appreciate yours for helping me out of this problem.

Thank you in advance!!

If Im getting better in this language, I will come back and help other users with their problems too!!

regards

This error probably happens because you called Response.GetString (hard to tell without the full error message from the logs).
You should use HttpUtils2. It will handle all the background communication for you.
