Do you have practical experience using the Room library for working with local databases in Android?

Yes, the Room library is a convenient ORM for working with a local SQLite database in Android. It simplifies creating, reading, updating, and deleting data while ensuring type safety and integration with LiveData and Coroutines.

Example of using Room:

@Entity(tableName = "users")
data class User(
    @PrimaryKey val id: Int,
    val name: String,
    val age: Int
)

@Dao
interface UserDao {
    @Query("SELECT * FROM users")
    fun getAllUsers(): List<User>

    @Insert(onConflict = OnConflictStrategy.REPLACE)
    fun insertUser(user: User)
}

@Database(entities = [User::class], version = 1)
abstract class AppDatabase : RoomDatabase() {
    abstract fun userDao(): UserDao
}

// Database initialization
val db = Room.databaseBuilder(
    context.applicationContext,
    AppDatabase::class.java, "app-database"
).build()

// Usage
val users = db.userDao().getAllUsers()

Room automatically generates code for database access, reducing boilerplate code and errors.
