Error In Creating Avd In Android Studio

I am new to android studio. my problem is when i try to create AVD its showing unknown error. see idea.log for details. I am working on windows8.

Solution 1:

Delete all the files and folder from a directory home//.android/avd It's for Ubuntu. In Windows it's also in the user's folder (.android/avd).

Solution 2:

Before you create the new Virtual Device, Try downloading via SDK Manager the API level you want on the Virtual Device. This should do it.
