This Tutorial will show you all needed Code to do Uploads to Dropbox.
Requirement for this tutorial: you need to have your App Dropbox-ready (see Tutorial I - Authentification).
Asuming you already have your app setup and you already have a accesstoken and Dropbox is initialized fully.
There are two kind of uploads to Dropbox. Normal uploads (which can be up to 150mb in one call) and big uploads which are using a Uploadsession.
Updated Date 20th june 2018
This tutorial will only handle the Uploads using a Uploadsession from version V0.40+ of the Dropbox V2 Library.
The default upload chunksize is 8MB. For now it is not chnageable.
While uploading it will raise an Progress Event
will be raised to inform about the finished upload.
I´ve tried it with a some big files.
