I'll be happy to help with any issues you're having with the Dropbox API, but I'll need some more information. Please reply with:

- the version number of the SDK you're using
- the exact steps to reproduce the issue, including the code snippet(s)
- the full text of the error/stack/any output

Thanks in advance!

    Thank you!

     

    (1) Dropbox core API: 3.0.2

    (2) Download the code reference: https://github.com/dropbox/dropbox-sdk-java/issues/66.

     

      Download interface click back to cancel, call stopDownload function:

     

          DbxDownloader<FileMetadata>  :  downloaer
      public void stopDownload() {
if (downloaer != null) {
try {
downloaer.close();
downloaer = null;
} catch (Exception e){
downloaer = null;
e.printStackTrace();
}
}
} 

     

    (3) stopDownload throws an exception:

      Thanks! We'll look into it.

      For our reference though, can you also share how you're constructing your client object?
