* drawable-mdpi (160 dpi, Medium density screen) - 48px x 48px
* drawable-hdpi (240 dpi, High density screen) - 72px x 72px

So, for the xxhdpi qualifier, you will need to create an icon of the size 144*144px for your launcher icon. You can either place it in the drawable-xxhdpi or the drawable-480dpi
EDIT: To add to the original answer to address cone of the comments by the OP.
As per this link: http://developer.android.com/guide/practices/screens_support.html#DesigningResources, alternative resources should be created using this ratio: 3:4:6:8 scaling ratio. However, if you are concerned about loosing quality with regards to your in-app drawable resource, consider using 9-patch images wherever possible. That will reduce or eliminate any loss of quality. The Android OS all by itself, does a remarkable job handling various screen sizes most of the time anyway.
As for the icon size 144*144px, create either of these two folder drawable-xxhdpi or the drawable-480dpi and place just your launcher icon of the said size in it. That should do it.
