Build me an Android keyboard app that works fully offline and keeps everything on the device. I want it to feel fast and polished, with swipe typing, autocorrect, word suggestions, emoji, clipboard history, voice input, and a settings screen where people can change themes and privacy options. The keyboard should learn from how each person types, so predictions get better over time, but without sending anything to a server or requiring an account.

Make it support a few clean themes, a privacy mode that stops learning for sensitive typing, and a way to export and import user data. Please include a simple companion settings app, and make sure it works well on Android 8 and up. If you need to check current docs for Android keyboard APIs or Rust integration, look them up online first.
