Build me an Android fitness coach app like a simple all in one health tracker and fitness community. I want users to sign up, create a profile, calculate BMI and daily calorie needs, track food, water, workouts, calories eaten and calories burned, and keep a daily diary with past records.

The app should also let users search or view nutritional information for foods, set weight loss goals, earn points when they hit goals, and see progress in a friendly way. Add a community area where people can share posts, comment, message each other, view profiles, see diaries or posts if allowed, and make connections.

There should also be a professional services side where trainers or health professionals can register as sellers, list services, and users can discover them, buy or request services, and leave ratings.

Use Java for Android, XML layouts, and Firebase for login, database, and storage. Please set it up so I can add my own Firebase project and google services file.
