I am able to share the game over screen. But can't figure out the way tolling the image to the Facebook page. Can you show me the tutorial for that?
Yes I'm wondering this to after setting the share for the game over screen. What the URL code we put in?
Share button picks the app that were installed on your device like fb, twitter, etc if you have a share button in your game than when you press this button a dialog box will appear which will ask you to choose an option to share you screen on fb, twitter etc select fb than your screen will share on you wall.(Also you can add share message so it will appears with your screenshot)
