Thanks for your quick answer. I tell you what I did and would like to do and if you have a better idea please let me know:

 

I have an android application which does the following: When a user presses a button in the app, it creates ssh connection with my raspberry pi which creates some files and uploads them to my dropbox account.

 

Until stopping v1, my application searched for the latest file that got uploaded to dropbox and downloaded it, but unfortuantely it's not working now. This is the best solution I could come up with. 

 

Do you have a better idea (how to throw back the files on raspberry pi to my app)?

 

Thanks

The official Dropbox API v2 Java SDK does offer the ability to upload and download files programmatically, just like in API v1. For example, in the Dropbox API v2 Java SDK, you can use the upload method to upload files:

https://dropbox.github.io/dropbox-sdk-java/api-docs/v3.0.x/com/dropbox/core/v2/files/DbxUserFilesRequests.html#upload-java.lang.String-

I can't offer general app development guidance, but if API v2 isn't working as expected for you, please share the code and error/output you're getting, and I'll be happy to help.
