A word of caution.
I used an android emulator a couple of months ago and set up a google email account just for the soul purpose of the emulator, and 2 days ago i tried accessing that account and google shut it down saying that it had been used in breech of their terms and conditions!
So, if you do want to use an emulator please dont give them your main gmail account, just make one up!
bluestack is the slowest emulator I have ever tried. On the same celeron laptop, marvel future fight has a low FPS while Memu has high FPS. Furthermore, memu supports hardware virtualization which helps memu to use more resources than the others (more than 1 core) => a lot faster than without virtualization
when using Memu, enabling hardware-virtualization is a must in order to get much higher performance
