Hello! I read some stuff related to this topic, but I am still not sure how to do it, so I would really appreciate if someone can help me. I want to be able to share stuff from my app, like a link to the game on Google Play. I know how to make a button and when clicked to use the Browser Go to URL option, but this allows me to do one link per button. I saw in many games when u click the share button you see a list with different social media and the customer can choose where they want to share my game. So how can I do it this way? Thank you!
I'm not sure if C2 support what are looking for, but I know for sure that 
cranberrygame selling his C2 Plugins, and one of them is what you are looking for, because I'm using in my game. I think it called ( cranberrygame_ShareApp ). Anyhow, you can buy the plugins from scirra site or his github page.
scirra: https://www.scirra.com/store/construct2-plugins/construct2-cordova-plugins-1662
His: http://cranberrygame.github.io/
You can look around and you may find another way or plugin for free, but if want faster solution then check out the plugin.
Good Luck
