In general, apps optimized for a tablet experience will work on Kindle Fire tablets. To improve compatibility with the Kindle tablets, we recommend you use APIs that are backwards compatible with the Android 4.0.3 platform (Ice Cream Sandwich API 15) for the Kindle Fire (2nd Generation), Kindle Fire HD 7", and Kindle Fire HD 8.9"; and with the Android 2.3.3 platform (Gingerbread API 10) for Kindle Fire (1st Generation).
