섹션 3 - 1 진행 중 JoinActivity에 myRef = database.getReference("message") 까지 하고 실행을 해 보니 데이터베이스에 정보가 올라가지 않고 아예 회원가입 자체가 되질 않고 있습니다. 정보를 입력하고 가입을 누르면 가입이 되지 않고 introActivity로 돌아가는 상황입니다.

어디서 문제인지 확인해보려 한 단계씩 하면서 실행을 해 보니

table = findViewById<TextInputEditText>(R.id.tableArea).text.toString()

introduce = findViewById<TextInputEditText>(R.id.introduceArea).text.toString()

이 부분을 입력 한 후에 실행을 했을 때 위와 같은 문제가 발생하고 있는데 어디가 문제인 걸까요..?

참고로 저는 JoinActivity를 아이디,비밀번호,번호(tableArea),소개(introduceArea) 이렇게 4개만 입력하게 구성했습니다.

package com.cockandroid.dating.auth

import android.content.ContentValues.TAG

class JoinActivity : AppCompatActivity() {

    private lateinit var auth: FirebaseAuth

        private var uid = ""
        private var table = ""
        private var introduce = ""

//    private val TAG = "JoinActivity"

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

        auth = Firebase.auth

        val newbtn =findViewById<Button>(R.id.newbtn)
        newbtn.setOnClickListener {
            val ID = findViewById<TextInputEditText>(R.id.IDArea)
            val password = findViewById<TextInputEditText>(R.id.passwordArea)

            table = findViewById<TextInputEditText>(R.id.tableArea).text.toString()
            introduce = findViewById<TextInputEditText>(R.id.introduceArea).text.toString()



            auth.createUserWithEmailAndPassword(ID.text.toString(), password.text.toString())
                .addOnCompleteListener(this) { task ->
                    if (task.isSuccessful) {
                        // Sign in success, update UI with the signed-in user's information
                        Log.d(TAG, "createUserWithEmail:success")
                        val user = auth.currentUser
                        uid = user?.uid.toString()

                        val database = Firebase.database
                        val myRef = database.getReference("message")

                        myRef.setValue("Hello, World!")
//                        updateUI(user)
//                        val intent = Intent(this, MainActivity::class.java)
//                        startActivity(intent)

                    } else {
                        // If sign in fails, display a message to the user.
                        Log.w(TAG, "createUserWithEmail:failure", task.exception)
//                        Toast.makeText(baseContext, "Authentication failed.",
//                            Toast.LENGTH_SHORT).show()
//                        updateUI(null)
                    }
                }
        }
    }
}

안녕하세요

혹시 로그가 나올까요?

그리고 강의 영상 기준으로 어디까지 되고 어디부터 안되었는지 플레이타임을 알려주시겠어요?

섹션3 -1의 8분 15초까지 따라하고 실행을 해보니 해당 문제가 발생하였고 처음부터 실행하면서 어디서 문제가 생기는지 봤더니 6분 20초 부분에서 해당 문제가 발생하였습니다.

로그캣은 다음과 같이 나왔습니다.
