You can use REPLACE strategy on conflict and declare insert method this way:

@Dao
interface UserDao {

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

Use the update annotation in your Dao, it would update based on the primary key (id in your case)

@Update()
void updateUser(User user);
