android - 身份验证 Android Studio (Kotlin) 后无法将用户信息存储到 FireBase 数据库

Question

这是我的注册活动。当按下按钮时，它会注册用户，但不会将其数据存储在数据库中。它显示用户在 firebase 控制台的身份验证选项卡中注册，但数据库中没有数据。这是我的应用程序注册活动。

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

    val signin_btn = findViewById<Button>(R.id.signin_link_btn)
    val signup_btn = findViewById<Button>(R.id.signup_btn)

    signin_btn.setOnClickListener {
        startActivity(Intent(this, LoginActivity::class.java))
    }

    signup_btn.setOnClickListener{
        createAccount()
    }
}

private fun createAccount() {
    val fullName = findViewById<EditText>(R.id.fullname_signup).text.toString()
    val userName = findViewById<EditText>(R.id.username_signup).text.toString()
    val email = findViewById<EditText>(R.id.email_signup).text.toString()
    val password = findViewById<EditText>(R.id.password_signup).text.toString()

    when {

        TextUtils.isEmpty(fullName) -> Toast.makeText(this, "Full Name is Required", Toast.LENGTH_LONG).show()
        TextUtils.isEmpty(userName) -> Toast.makeText(this, "UserName is Required", Toast.LENGTH_LONG).show()
        TextUtils.isEmpty(email) -> Toast.makeText(this, "Email is Required", Toast.LENGTH_LONG).show()
        TextUtils.isEmpty(password) -> Toast.makeText(this, "Password is Required", Toast.LENGTH_LONG).show()


    else -> {


        val mAuth: FirebaseAuth = FirebaseAuth.getInstance()

        mAuth.createUserWithEmailAndPassword(email, password).addOnCompleteListener{
            task ->
            if (task.isSuccessful)
            {
                saveUserInfo(fullName, userName, email)
            }
            else
                {
            val message = task.exception!!.toString()
            Toast.makeText(this, "Error: $message", Toast.LENGTH_LONG).show()

            mAuth.signOut()

                }
            }
        }

    }
}

private fun saveUserInfo(fullName: String, userName: String, email: String) {

    val currentUserID= FirebaseAuth.getInstance().currentUser!!.uid
    val usersRef: DatabaseReference = FirebaseDatabase.getInstance().reference.child("Users")

    val userMap = HashMap<String, Any>()
    userMap["uid"] = currentUserID
    userMap["fullname"] = currentUserID
    userMap["username"] = currentUserID
    userMap["email"] = currentUserID
    userMap["bio"] = "Hey I am using Instagram Clone App."
    userMap["image"] = "https://firebasestorage.googleapis.com/v0/b/instagram-clone-565fe.appspot.com/o/Instagram%20Clonde%20Default%20Images%2Fprofile.png?alt=media&token=494e98e8-8e7d-40ea-8102-97849ac546b7"

    usersRef.child("Users").child(currentUserID).setValue(userMap).addOnCompleteListener {

            task ->
        if(task.isSuccessful){
            Toast.makeText(this,"Account has been created Successfully.", Toast.LENGTH_SHORT).show()
            val intent = Intent(this, MainActivity::class.java)
            intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK or Intent.FLAG_ACTIVITY_NEW_TASK)
            startActivity(intent)
            finish()
    }
        else
    {
        val message = task.exception!!.toString()
        Toast.makeText(this, "Error: $message", Toast.LENGTH_LONG).show()
        FirebaseAuth.getInstance().signOut()
    }
    }
}
}

我的数据库的规则是

{  
  "rules": {
    ".read": "true",  // 2021-8-5
    ".write": "true ",  // 2021-8-5   
  } 
}

这里是项目的gradle依赖
