Laptops are commodities these days, brand doesn't really matter. You need to think about the specifications.
- How much RAM do you need?
- How much disk space
- What processor speed?
- What operating system (Windows, Mac or Linux)?
- How big a screen?
- Wifi, Bluetooth and USB ports (although pretty much every laptop has these)
I use an Intel i5 processor with 16G of RAM and 500G of disk space. This is plenty good for running an Android Studio (which is pretty resource heavy), Eclipse (for Java development) with MySQL running in the background as well as whatever else I happen to be doing at the time.
Figure out what specs you need, and then pick any of the reputable brands that offer them at a good price.
