Build me a simple Android demo app like a small business and inventory manager. I want it to let someone manage multiple businesses, add expense and purchase entries, and see the totals update automatically as new records are added. Keep the data saved locally on the device so it still works after closing the app.

Make the interface clean and modern, with a home dashboard, screens for expenses and purchases, and a side menu for moving around the app. Please include basic inventory and business tracking where it makes sense from the flow. I also want a language option so the app can switch to Hindi.

Use a modern Android approach with Kotlin and a composable UI, and structure it cleanly so it feels like a real sample project rather than a quick mockup. If anything is unclear, look up current Android docs online and fill in the sensible details.
