Postfile ProgressBar

alexposta2 · May 7, 2012

Hi,
does anyone know how to create a progressbar for httputils.postfile?
I've tried many method without success.

thank you for support.

There is a related discussion in HttpUtils thread.

Note that HttpUtils.PostFile sends smaller files (< 1mb) by first reading the whole file to a bytes array. If you want to pass a CountingInputStream then you will need to remove this check.

Hi Erel,
Thank you for your reply.
Can you link me the post # how to discuss about progress?
I've searched all post without success.

Alessio

Unfortunately this is about download.
I woul'd like to say if is possibile to chek upload file.

thank you
Alessio

thanks to erel sample i've solved my issue.
I've modified the httputilsservice:

B4X:

Dim cout As CountingInputStream

B4X:

If cout.IsInitialized Then cout.Close
cout.Initialize(PostInputStream)
req.InitializePost(link, cout, PostLength)

thank you
Alessio

Hi Alessio,
i'm going crazy with progressbar upload.
Would you be so kind to give me further details about this?
thanks

If you are using HttpUtils2 then you should modify HttpJob.PostFile:

B4X:

Public Sub PostFile(Link As String, Dir As String, FileName As String)
   Dim length As Int
   If Dir = File.DirAssets Then
      Log("Cannot send files from the assets folder.")
      Return
   End If
   length = File.Size(Dir, FileName)
   Dim In As InputStream = File.OpenInput(Dir, FileName)
   cin.Initialize(In)
   req.InitializePost(Link, cin, length)
   CallSubDelayed2(HttpUtils2Service, "SubmitJob", Me)   
End Sub

cin is a global variable of type CountingInputStream. You should use a timer to check cin.Count and report the progress.

erel, above solution is not working in jellybean, kitkat. cin.Count is zero initially then becomes total size of file. however upload is still in progress. does anyone have similar problem ?

Try this example: Download huge files with HttpUtils2

yes for download it is working with above example. but when i use postfile in above example, same problem occurs. progress bar is initially zero and then becomes 100.

postfile progress is working fine in 2.2 & 2.3 android. since 4+ i am having problem. please help.

What is the file size?

file size is less than 1 mb. i have removed bytesarray method in postfile as mentioned above in this thread.

Try to send a large file and see whether the process is tracked. It is possible that it reads the complete file to an internal buffer.

yes upload progress works for larger file. buffer was reading complete file at once for smaller files. however for large file also, at end part of upload when progress is 100% but in actual last block of buffer is still uploading.

is it possible to change buffer size or any other workaround for this. like count data sent over http rather than file input buffer read completed size.

This is indeed not an accurate way to monitor the progress as it monitors the input file progress.
You can make it more accurate. Use CountingInputStream to monitor the progress between 0 to 90%. Jump to 100% when JobDone is called.
