Android xhdpi icons -

is there published size xhdpi application icons? or use hdpi ones @ 72x72?

the supporting multiple screens page contains image:

the image shows every assets xhdpi has 2 times size of mdpi asset.

also hackbod gave answer in google groups

xhdpi_size = (hdpi_size) * (xhdpi_densitity / hdpi_density)
in other words, 2x mdpi size.
launcher icon : 96x96
