Progress Listener for Downloads?

[Aaron M.10]

Hello,

Just wondering if anyone knows whether the Dropbox API Core (Java) supports some sort of ProgressListener capability OR will I need to write one myself?

I have a website that uses the old "dropbox-java-sdk v1.3" (org.syncloud) and this came with a class com.dropbox.client2.ProgressListener that could be used to update the UI for download progress such that the progress of larger downloads could be presented to the user i.e. % completed of total bytes read. My users now expect this so updating to below version I have regressed functionality (or so it seems).

<dependency>
  <groupId>com.dropbox.core</groupId>
  <artifactId>dropbox-core-sdk</artifactId>
  <version>[1.7,1.8)</version>
</dependency>

Anyone come across this problem or know of a solution?

Thanks in advance.

Unfortunately, the current version of the Java Core SDK doesn't offer a progress listener, but I'll be sure to pass this along as a request.

How to Obtain the java core sdk upload / download progress ?

The Java SDK still doesn't offer upload/download progress listeners, but I'll add your vote to the feature request.

The Dropbox API v2 Java SDK now offers progress listeners for uploads and downloads. This has been released in v3.0.9:

https://github.com/dropbox/dropbox-sdk-java/releases/tag/v3.0.9

There's an example of using it with with the uploadAndFinish method ( https://dropbox.github.io/dropbox-sdk-java/api-docs/v3.0.x/com/dropbox/core/DbxUploader.html#uploadA... ) for an upload here:

https://github.com/dropbox/dropbox-sdk-java/blob/master/examples/upload-file/src/main/java/com/dropb...

It works the same way with file downloads; the download method ( https://dropbox.github.io/dropbox-sdk-java/api-docs/v3.0.x/com/dropbox/core/DbxDownloader.html#downl... ) optionally takes a ProgressListener parameter the same way.
