I Can't download pdf file in webview with the codes below? Is there any idea? I use HttpUtils2 library.

B4X: 
Sub WebView1_OverrideUrl (Url As String) As Boolean
   If Url.EndsWith(".pdf") Then
        Dim j As HttpJob
     j.Initialize("pdf", Me)
     j.Download(Url)
     Return True
    Else If Url.IndexOf("mailto:") > -1 Then 
     Dim Intent1 As Intent
     Intent1.Initialize(Intent1.ACTION_VIEW, Url)
     StartActivity(Intent1)
     Return True
   Else
     Return False
   End If
End Sub

Sub JobDone (Job As HttpJob)

End Sub

I did as you said. I used Erel's "LargeFileDownload.zip" example. I added libraries which Erel said. But I received error logs below;

B4X: 
Sub WebView1_OverrideUrl (Url As String) As Boolean
   If Url.EndsWith(".pdf") Then
        Dim dd As DownloadData
        dd.url = Url '<--- download link
        dd.EventName = "dd"
        dd.Target = Me
        CallSubDelayed2(DownloadService, "StartDownload", dd)
     Return True
    Else If Url.IndexOf("mailto:") > -1 Then 
     Dim Intent1 As Intent
     Intent1.Initialize(Intent1.ACTION_VIEW, Url)
     StartActivity(Intent1)
     Return True
   Else
     Return False
   End If
End Sub

Sub dd_Complete(Successful As Boolean)
    Log("Job completed: " & Successful)
End Sub


Error logs;

This is small project. Zip file is given attached. You can see pdf files in;

1) Taxi Driver Login - Driver Registration - Contract
2) After Customer login at the ? mark at the top of map. (Username: baris--karadeniz@hotmail.com , password: 123456)

Your code
B4X: 
Sub dd_Complete(Job As HttpJob)
    Log("Job completed: " & Job.Success)
    Dim o As OutputStream
    o = File.OpenOutput(File.DirDefaultExternal, "l.bal", False)
    File.Copy2(Job.GetInputStream, o)
    o.Close
    Job.Release
End Sub


saves the pdf as l.bal in DirDefaultExternal.

Ok. I saw it in the "files" directory. I have 2 questions;

1) pdf files were in 2 places as I wrote above. The first place (Taxi Driver Login - Driver Registration - Contract) is not downloaded. When I press on it nothings happen. (Service doesn't start so job is not completed) What can be the reason. It is in the pop-up menu.

2) After downloading l.bal, I want to open on the screen immediately. Should I write into "Sub dd_complete"? And what I need to write?

Thanks for your help.

Contract) is not downloaded
Click to expand...
I cant reach the popup once logged in. There is no button to logout
But i guess you need to capture it in override url, extract the filename and remember it. Or get the url in dd_complete again to extract the url to get the filename out of it...

The url i get in my pc browser points to http://www.taksi-m.com.tr/TAKSIMDriverContractR4_DE.pdf
So i guess you should be able to download the pdf manually with httputils

If you turn your phone horizontally, there is a log out button at the top right corner.

Before login did you try to push on "contract"? It is also URL like the pdf after login. It is totally same procedure. Why I need to write something else?

There happens nothing with my phone (Note II) May be there is a problem with phone. I will try it with another phone. It is not important the name is again l.bal. Because it will be opened as soon as downloading finish. And it will change if another pdf file is downloaded. I think it will be downloaded onto old l.bal.

After downloading l.bal, I want to open on the screen immediately. Should I write into "Sub dd_complete"? And what I need to write?

     j.Initialize("pdf", Me)
     j.Download(Url)
     Return True
