I got the reply from Amazon Appstore Team. See the following:
Hi,
Thank you for writing in. To determine if your app is available on Kindle Fire, type the name of your app in the search field with “Apps for Android” in the Search dropdown, then click GO. If you can see the Kindle Fire/Available on Kindle Fire search refinement option in the left column, click the box to make sure your app(s) are available on Kindle Fire. If you can’t see the Available on Kindle Fire refinement, your app is not available on Kindle Fire.
Best regards,
