Resources vs. SQLite
One tangential point...
Amazon's guidelines for Kindle Fire apps state that apps cannot require an SD card, so going this way might rule out Kindle Fire compatibility. (Bad!)
The version from today actually recommends
that you deploy a smaller APK that downloads and installs quickly, and then upon first launch downloads additional resources and saves them on a local file system.
for larger apps instead of packaging it altogether. Additionally, what they forbid seems to be [emphasis mine]
copying, recording, downloading, storing, or similar actions of any type of video or audio content onto the Amazon Fire TV or Fire TV Stick device, any SD memory card or any connected external storage (where applicable).
So that restriction seems obsolete now.
