Share score on facebook *Without facebook SDK* (ANDROID)

I have a share button after player has finished the game.
I wan`t to share the score on facebook with a link to the play store app.
I have thought of something like this:
I have scored XX on ! (with a picture of the app and a link to the app).
IMPORTANT: i try to avoid using Facebook sdk.
can someone please help me with that?
Is that even possible doing that without the fb sdk?

Follow this tutorial: Sharing Scores on facebook and twitter without using SDK - Unity 3D - YouTube
