At the moment we are building an application which works with attachments. We need to integrate the app with the Media Viewer, so users can open the file from our app without going to the section and browsing through these files.
As the app works in the isolated environment we cannot do anything with the native attachments section, when the user locates the necessary file. In our case we can just let him/her download this file without opening it.
Is there any way to integrate it anyhow with the Media Viewer without selling a soul to the devil?
