[AC Question]

New app shows up on my android phone. When I try to download on my kindle, it shows installed, but there is no icon to open.

Welcome to Android Central! How are you downloading and installing the app on your Kindle? Through the Amazon Appstore? Or have you modified the Kindle to run Google Play Store? You know, of course, that Google Play Store doesn't run natively on the Kindle--you have to jump through a bunch of hoops.
