How to get a pop-up hint on Android?

Question

How can I get a pop-up hint in code playground on Android? For instance, coding using browser or IDE on my laptop, I type smth like 'myclass.' and press CTRL+Space to see what variables and methods are present in myclass. Can this be done on a tablet?

Answer 1

I meant in sololearn code playground. But thanks anyway, NoName.
I noticed that sometimes pop-ups appear by themselves and sometimes don't. Perhaps it depends on internet connection speed.
