전 실패뜨는데 왜 성공이 안뜨는가요?

com.example.chatting_video을 이름 바꾸는 것도 알려주세요.
example 대신에 제 아이디 tkhpsch 쓰고 싶은데 안되네요.
어떻게 성공했는지 알고 싶어요. Log.d에서 Log 임포트가 안되는데요?

package com.example.chatting_video

class MainActivity : AppCompatActivity() {

    private lateinit var auth: FirebaseAuth// ...

    private val TAG: String = MainActivity::class.java.simpleName


    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)

        auth = FirebaseAuth.getInstance()

        auth.createUserWithEmailAndPassword("tkhpsch@gmail.com", "123123")
            .addOnCompleteListener(this) { task ->
                if (task.isSuccessful) {
                    // Sign in success, update UI with the signed-in user's information

                    Log.d(TAG, "성공")

                } else {

                    Log.d(TAG, "실패")


                }
            }

        login_button_main.setOnClickListener {

            val intent = Intent(this, LoginActivity::class.java)
            startActivity(intent)
        }



        }


    }
