API v2 migration issue

[Rerware L.]

Per your request, we are migrating Android v1 to your new SDK V2
com.dropbox.core:dropbox-core-sdk:2.1.1

One feature that doesn't exists or can't find is the Progress Listener that
existed in v1 (com.dropbox.client2.ProgressListener). It enabled
us to check the progress of the upload or download. This is very important for large files and user input.

Please add this feature ASAP, as the current no progress is
not user friendly at all (imagine the user is uploading 50MB file
from Android device with no progress), the user simply might kill the app and thinks that it is stuck while it is actually uploading?

Please advice.

Thanks! I'm sending this along to the team as a feature request.

Any update to support ProgressMonitor in API v2? V1 is set to be retired as of 6/28/2017. How Dropbox force apps to move to v2 without providing this essential function?

I don't have an update on this feature request right now.

Note that we actually just announced a general extension for access to API v1 though, until 9/28/2017:

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.
