Android: How can I download file with my custom Download manager using bearer access token?

Explorer | Level 3

I'm creating an app that help user download their from from their cloud drives (Dropbox, Google Drive). I create an download manager to let user download, pause, resume, eta, speed...

So, how can I get the direct download link to a file in Dropbox to download it with the granted access token?

With Google Drive, I can by setting the request header

"Authorization" to "Bearer <access_token>"

I read the Dropbox API but could not find any info about this.  I don't use the API to create file shared link, because when loading the files list for user to choose to download, create share link for all of them are impossible (take long long time) and users don't want to share files. 

Please help!

To download a file directly from a connected account using the Dropbox API, you can use the /2/files/download endpoint. In the official Dropbox Java SDK, that's available the download methods.

Or, to get a temporary direct link to a file, you can use /2/files/get_temporary_link, which is getTemporaryLink in the Java SDK. 

Either way, you authorize the call by setting the user's access token in the "Authorization" header like you described. If you're using the Java SDK, it will build the header for you.

The difference is that the /2/files/download endpoint will return the file data directly in the response, whereas the /2/files/get_temporary_link endpoint will return a temporary link to the data in the response. You can then use that link to download the data however desired, without using the access token.
