I like Lenovo or ASUS systems for non-gaming use. Any system with a good size SSD, 250gb or so, 8 GB of RAM will be fine. This one should be great, decent CPU, even has a lower end video card so you can play some games on it http://skyland.com.bd/product/asus-vivobook-s14-s430fn-full-hd-laptop/
Acer Aspire E15, Dell inspiration 17370, Acer Swift 3 in my point of view these are the good laptops to work with the android studio. Choose as per your budget.
