How to find out from code if my Android app runs on emulator or real device?

Question

I have read this stackoverflow thread already and I tried using the code given in that answer to find out if I run my code on the emulator or on a real device:

Answer 1

Following one is correctly detect my emulator

if (Build.BRAND.equalsIgnoreCase("generic")) {
              //"YES, I am an emulator"
       } else {
              //"NO, I am NOT an emulator"
       }
