If you want a fast way to run Android, you can also use a VirtualBox image, it is significantly faster than the emulator in the SDK:
* Open SDK manager, install Intel image for your preferred SDK version and the "Intel Hardware Accelerated Execution Manager" from the Extras section
* Find the HAXM installer in SDK/extras and run
* Create Intel-based AVD

The emulator does take a while to start but that's a one-time cost.
Installing Play Store app on emulator still requires some hacky workarounds.
