I have designed a simple android app which based on some input from the user redirects the user to certain part of my wordpress site.
The problem that I am facing is that before that, I need to check if the user is already logged in and if not to give him the possibilit to log in.
I checked around and everyone is talking about the android app but I need the login to be done from my own app.
Any idea/orientation how that can be done?
