Android Question Downloading image question

[GaNdAlF89]

Hi, I have a question with the download of images. I want to download an image before that execution of calling routine continues.

Something like:

Sub Authentication
'initial code

LoadImage 'Function

'other code that I want to execute after the download of image

End Sub

Sub LoadImage

Dim imageRequest As HttpRequest
imageRequest.InitializeGet(url & "imagename.jpg")
     
Client.Execute(imageRequest,1)

End Sub

Sub Client_ResponseSuccess(Response As HttpResponse, TaskId As Int)

Response.GetAsynchronously("ResponseSub",File.OpenOutput.......
 
End Sub

Sub ResponseSub_StreamFinish (Success As Boolean, TaskId As Int)
 
If Success = True Then
   
  Photo.Initialize......... 'Photo is a Bitmap
   
End If
 
'Now I want to execute the other code of "Sub Authentication" after calling "LoadImage"

End Sub

How can I do?

You should use HttpUtils2 and handle the JobDone event.

Is JobDone event similar to ResponseSub_StreamFinish? Does it works asynchronously with the rest of code? How it works?

 

[Erel]

It is asynchronous. Network calls are always asynchronous. However it is much simpler than working with HttpClient directly.

Yes, I know that network calls are always asynchronous. I mean something that "waits for" the network response, either 'success' or 'error' events, and then it continues the execution.
