I need to do both of these download tasks (with targetSDK=22):

  1. Get HTML from a webpage on a website
  2. Download a large (20mb) apk file from a website

I am able to download the HTML from a website using okHTTPUtils2 (version 2.82) with this code:

B4X:
Sub cmdGetWebpage_Click
    Dim job1 As HttpJob
  
    job1.Initialize("", Me)
  
    job1.Download("https://mywebsite.com/index.html")

End Sub

Sub JobDone (Job As HttpJob)
  
    If Job.Success = True Then
        WebView1.LoadHtml(Job.GetString)
    End If
          
    Job.Release

End Sub

And it works great.

Then, I tried to download a 20MB file using this code:
B4X:
Sub DownloadAndSave (Url As String, Dir As String, FileName As String) As ResumableSub
   Dim j As HttpJob
   j.Initialize("", Me)
   j.Download(Url)
   Wait For (j) JobDone(j As HttpJob)
   If j.Success Then
       Dim out As OutputStream = File.OpenOutput(Dir, FileName, False)
       File.Copy2(j.GetInputStream, out)
       out.Close
   End If
   j.Release
   Return j.Success
End Sub

But for some reason, the job always "completes" with the downloaded file being only 40k in size (resulting in an invalid file)

So, then I found this "custom" version of okHTTPUtils2 for downloading large files:


And it properly downloads the 20MB file great!

But when I tried to download the webpage using the same code I posted above but with using this other "custom" okHTTPUtils2, it gave me this error:

I spent over a day trying different things to get it to work so that I can do both tasks, so any help would be greatly appreciated.
