emulator does not launch at all
When i click on the run button the emulator does not load at all. It might be the case that emulator is slow...but on an average how much time does it take to an emultor to load?
Genymotion is an option, but the built-in android device emulator is much better and faster than it used to be. From Android Studio, try launching an emulator using the AVD (Android Virtual Device) Manager. This should let you set up whatever device you want. You can then start it running from there. Once it's up and running, you can then try to run your app. It should launch quickly since the virtual device will already be ready.

Goto Preferences -> Android SDK -> SDK Tools -> Install Android Emulator. This solved the problem for me.
