title: How to import set of icons into Android Studio project
body: <p>I downloaded collection of icons from <a href="https://developer.android.com/design/downloads/index.html" rel="noreferrer">Android Developers center</a>
  Each icon in this collection is ordered in forlders according to its resolution: drawable-hdpi, drawable-mdpi, drawable-xhdpi, drawable-xxhdpi.</p>
  
  <p>Is there a way to import all the 4 icon's files in one action to Android Studio or I need to copy it one by one? 
  (when I used new->Image Asset , I had to fill a file path, I couldn't fill it with folder path)</p>

  According to <a href="https://stackoverflow.com/questions/22370237/how-do-i-import-a-custom-made-icon-in-android-studio">this SO question</a>, seems like there is a way to generate the 4 size of icons by <a href="http://romannurik.github.io/AndroidAssetStudio/index.html" rel="noreferrer">Android Asset Studio</a>, and then import the zip file directly to your Android Studio project res folder - has anyone used it? </p>
