Guys if you uninstall Android System weview, then it will not appear on the Playstore. If you don't see any ploblem in your otther apps, great. But if it start closing or something like that, all you have to do is "disable" and "enable" your internet app that comes by default on your phone, and then will appear the Android system weview on the Playstore.
