We released a new Sharing component about a week ago, and I recorded a rough and ready video for it. It uses and Android Intent to share information (a message or a file, or both) with other apps that are ready to handle the data provided.
We had to iron out a few things, such as paths coming from other components like the ImagePicker or the Camera. We also had to deal with the fact that the dialog would come up really big for certain actions, and on certain devices. We have a fix for all of that, and it's on review right now, but will soon be in our github repo; it might take a bit longer to go live (next release for sure, but we don't know right now when that is happening).
