Best Practice - Adding your App to the Android Share Menu

Question

My App sends files(all mime Types) over a TCP connection and hence I wanted my app to appear in the Android Share menu.

I added the following intent filters to my Activi

Answer 1

I tried to deal with this issue and I pretty sure that samsung's gallery uses some custom action for sharing through that menu. Taking into account that all the listed application are preinstalled ones it's obvious that Samsung agreed with all of the listed application developers to use it's custom intent action.

I have also tried to contact to Samsung and they haven't replied yet.
