[mohsen nasrabady]

how can download file with resume supported

[thedesolatesoul]

Do you have an example you want to convert?

 

[sorex]

you still need to rely on the web/ftp server if it supports resume or not.

 

[mohsen nasrabady]

yes there is many example in stockoverflow.com

 

[mohsen nasrabady]

please see this

As far as I am aware that code doesnt support auto-resume.
Only if you set the Pause method in DM, it allows you to Resume.

Where are you downloading the files from? Most http servers don't support this feature.

i have a download host and an app in cafebazaar.ir that download psx rom from my server
because of the big size i need download manager with resume
my downlod host supported resume
i plan to add psp game and the size of psp larger than psx

If you find a good one let me know. The first one as you said is paid and the second one doesnt have any comments or documentation.

 

[mohsen nasrabady]

i think the java files in src/services of the second is good

 HttpURLConnection connection = (HttpURLConnection) url.openConnection();
    if(ISSUE_DOWNLOAD_STATUS.intValue()==ECMConstant.ECM_DOWNLOADING){
        File file=new File(DESTINATION_PATH);
        if(file.exists()){
             downloaded = (int) file.length();
             connection.setRequestProperty("Range", "bytes="+(file.length())+"-");
        }
    }else{
        connection.setRequestProperty("Range", "bytes=" + downloaded + "-");
    }
    connection.setDoInput(true);
    connection.setDoOutput(true);
    progressBar.setMax(connection.getContentLength());
     in = new BufferedInputStream(connection.getInputStream());
     fos=(downloaded==0)? new FileOutputStream(DESTINATION_PATH): new FileOutputStream(DESTINATION_PATH,true);
     bout = new BufferedOutputStream(fos, 1024);
    byte[] data = new byte[1024];
    int x = 0;
    while ((x = in.read(data, 0, 1024)) >= 0) {
        bout.write(data, 0, x);
         downloaded += x;
         progressBar.setProgress(downloaded);
    }

i found this java code that can resume a download

 

[thedesolatesoul]

After a while I realized Android DownloadManager already supports resuming downloads if the server supports it.
Try @warwound excellent library: https://www.b4x.com/android/forum/threads/downloadmanager-tutorial.22307/

Once you get it to work, can you post back to see if the download is actually resumed or it is restarted from the beginning?

 

[mohsen nasrabady]

i already used this library and i know that but android download manager try some times when the connection problem
and after a few minutes that the connection problem the download fails and can't resume that

 

[mohsen nasrabady]

i believe b4a very strong i will work on it and i hope that i can build a download lib
if succeess i will publish the lib in forum
