Also there are a issue that sometimes happen of android running out of memory when reescaling the xhdpi. I had that issue once, and it was very annoying to figure what it was, who would wonder that putting lower resolution icons in your app would make it stop crashing for out of memory? Later I saw another guy in the same company with the same issue (but on another device), it was good that I knew exactly what it was this time :)
