Hey Greg, thanks for your answer.
I was hoping there is a Dropbox Chooser from the SDK that also includes the Authorization part. (as Google Picker works - select something after you authorize the app).
The complete story of my project consist in two apps. The user story is being able to display the photos you have from a dropbox folder, but this app does not have any user interaction. So in order to read the files from a folder, I need the access_token and the folderId.
There is a different app for that where user logs with getAuthenticationUrl and selects a folder with Dropbox Chooser and then, I pass this config object to the other app.
I was hoping I could launch both flows (authorization and file picking) together, not separately.
I started my own pseudo-file picker by 'navigating' dynamically with filesListFolder but maybe I am missing something and there is a better solution.
Have a wonderful day,
