Ways of transferring data between 2 apps?

[Android Central Question]

I am developing an app which by design should accept request from other apps(with some authentication token) and should be able to send requested data(media file or address of media file in local storage). I am not able to do it without switching between apps. Is there a way to do so that i don't know? Thanks in advance.

Not liking what I'm seeing from the user perspective. Q might never be loaded on this phone...
