title: Theare aren't different drawable folders on Android Studio
body: <p>I m trying to integrate different image size in my app but the problem is that in Android Studio there are not the drawable-Idpi,mdpi,hdpi,xhdpi folders.
  I ve checked already other threads and the answers were that I just need to skip into the Project view instead of the Android one. But the results are the same. There is just one generale folder called drawable</p>
