Answer 1

You do not need xxxhpdi for most of your images. You only need xxxhdpi for your launcher icon. Please see http://developer.android.com/guide/practices/screens_support.html

You should not use the xxxhdpi qualifier for UI elements other than the launcher icon.

It's pretty clear in the above quote. In the example folder layout they give, they show all the densities for the res/drawable folders up to -xxhdpi, but then they show the res/mipmap folders up to -xxxhdpi. Here are more quotes:

xxxhdpi Resources for extra-extra-extra-high-density (xxxhdpi) uses (~640dpi). Use this for the launcher icon only, see note above.

The mipmap-xxxhdpi qualifier is necessary only to provide a launcher icon that can appear larger than usual on an xxhdpi device. You do not need to provide xxxhdpi assets for all your app's images.
