Examples of Room database usage in production apps?

Room database is a part of Android's Jetpack components and provides an abstraction layer over SQLite to allow for more robust database access while harnessing the full power of SQLite. This example covers the application of Room in production apps.

        // User entity representing a table in the database
        @Entity(tableName = "users")
        public class User {
            @PrimaryKey
            @NonNull
            private String username;

            private String email;
            private String password;

            // Getters and Setters
            public String getUsername() {
                return username;
            }

            public void setUsername(String username) {
                this.username = username;
            }

            public String getEmail() {
                return email;
            }

            public void setEmail(String email) {
                this.email = email;
            }

            public String getPassword() {
                return password;
            }

            public void setPassword(String password) {
                this.password = password;
            }
        }

        // DAO interface for database operations
        @Dao
        public interface UserDao {
            @Insert
            void insert(User user);

            @Query("SELECT * FROM users WHERE username = :username")
            User getUserByUsername(String username);

            @Delete
            void deleteUser(User user);
        }

        // Database definition
        @Database(entities = {User.class}, version = 1)
        public abstract class AppDatabase extends RoomDatabase {
            public abstract UserDao userDao();
        }

        // Implementation of Room database setup
        AppDatabase db = Room.databaseBuilder(getApplicationContext(),
                AppDatabase.class, "database-name").build();
