Android xhdpi icons

Is there a publis开发者_Go百科hed size for xhdpi application icons? Or do we just use the hdpi ones at 72x72?

The supporting multiple screens page contains this image:

the image shows that every assets for xhdpi has two times the size of a mdpi asset.

Also Hackbod gave an answer in the Google Groups

XHDPI_SIZE = (HDPI_SIZE) * (XHDPI_DENSITITY / HDPI_DENSITY)
In other words, 2x the mdpi size.
Launcher Icon : 96x96
