AumGupta/BoostX ? reverse-engineered prompt

Build me an Android app called BoostX that helps people make audio louder than the normal system limit in a simple, polished way. It should have a clean modern interface with a volume slider, a boost slider, and a clear way to see what audio device is currently active and what its output details are. The boost control should work in two modes, one that changes in steps by default, and one that feels smooth and gradual. Use a minimal design with Material style components, and make it feel fast and easy to understand for someone who just wants louder sound without fiddling around.

Please make sure it uses the Android audio APIs to do the actual sound enhancement, and keep the app lightweight and optimized. If anything about current Android behavior or the APIs has changed, look up the latest docs online before implementing it.
