I wasn't able to install an emulator to my android studio installation. So, I copied this link from the studio and downloaded the zip file. Now I need help on how to manually install it using the zip files I downloaded.

I had a problem downloading the Emulator(Image files) from the android studio. So when you try to run your app witout an emulator. It asks for an option to create a new emulator wherin it'll download the required files. It use to download 60-70% and give error. So I used the link in the download dialogbox, and manually downloaded the zip file. Now that zip file needs to be extracted and has to be pasted in the sdk folder.
sdk/system-images/android-(api level)/(extracted folder)
