How to share data between multiple applications?
I have apps A, B, C and D and I need to share data from these apps for a specific app (E)
(Basically the login data, to auto login. Like Messenger does, retrieving Facebook access data).
This way the app will only receive data from other applications when requested. I have already seen and I was able to share data between two applications by

I wanted to know another way to share this data and make this automatic login.
