Answer 1

Just to make you aware and remind :

The Carousel icon on the kindle fire should be as referred to the Amazon Guide Lines :

Kindle Fire (1st Gen) : 322x322 px

Kindle Fire :  365x365 

Kindle Fire HD 7" : 425x425

Kindle Fire HD 8.9 : 675x675

But as per android standards , Launcher Icon Size is non rather than :

ldpi (120 dpi) (Low density screen)             36 x 36 px 
mdpi (160dpi)(Medium density screen)            48 x 48 px 
hdpi (240 dpi)(Highdensity screen)              72 x 72 px 
xhdpi (320 dpi) (Extra-high density screen)     96 x 96 px
