Julow/Unexpected-Keyboard ? reverse-engineered prompt

Build me a lightweight, privacy conscious Android keyboard app like Unexpected Keyboard.

I want a clean open source keyboard that is easy to use every day, but especially good for typing extra symbols and special characters by sliding from the corners of each key. It should feel fast and simple, with no ads and nothing creepy going on in the background. The keyboard should also make it easy to reach settings and other useful actions with swipe gestures, and it should work well on a phone without taking up much space or battery.

Please make it polished enough to install and use, with a nice looking keyboard layout, good default behavior, and support for multiple languages if that fits naturally. If you need to check anything about current Android best practices or build setup, look up the latest docs online.
