Oh, don't play Pokemon go on any emulator (BlueStacks, Nox,...) Niantic will block your account (I used to).
You can use BlueStacks but it's kinda lag and sluggish (i have to uninstall right away, i couldn't use any app). Another solution is to use arc Welder extension on your Chrome browser (this is an extension from Google so you can trust). Install Meez Stickerz apk from here (http://choilieng.com/apk-on-pc/air.m...p.stickers.apk
- actually i just generate from Google Play Store url so it is pure and safe to download). I like this way best 'cos i don't have to install any software and very safe for my PC.
