It's neccesary install IONICONS to display the social icons?

I cannot display in my app html, javascript, whatsapp or youtube icons in my app

Do i need to install it in my app? What’s the process?

No Ionicons comes by default with Ionic apps.

How are you attempting to use these particular icons?

I cant use the HTML5 or JS icon on my app on android.

Maybe i need to install this
