I am just testing my Android 4+ on a Kindle Fire. Most things work fine but the launcher icon that is displayed in the Carousel is very blury. I think the reason for this is quite obvious:
The Kindle system expects some large versions of the icon:
Kindle Fire HDX 8.9" (3rd Gen) 624 x 624
Kindle Fire HDX 7" (3rd Gen) 562 x 562
Kindle Fire HD 7" (3rd Gen) 375 x 375
Kindle Fire HD 8.9" (2nd Gen) 675 x 675
Kindle Fire HD 7" (2nd Gen) 425 x 425
Kindle Fire (2nd Gen) 365 x 365
Kindle Fire (1st Gen) 322 x 322
If the system looks for these sizes the best fit it the 192x192 xxxhdpi version of the launcher icon which is this than scaled up. That the result is blury is not a big suprise.
The Question is how I can add the additional sizes of the icon to the app? The Kindle sizes are no standard sizes for the Launcher icon. Is there some kind of naming convention or a special folder within the app I have to place the files in?
