Android Studio: java.lang.IllegalArgumentException: Given String is empty or null

Question

I'm currently working on my first project, so I'm sorry if it sounds like a stupid question.

I'm having trouble with a piece of code that should attempt to create a Firebase acccount with the email and password provided in the text boxes in the UI when you click a button. Instead, whenever I click that button, the app crashes with the error: java.lang.IllegalArgumentException: Given String is empty or null.

Code:

    //Create new User
    var email = emailID.text.toString().trim()
    var pwd = passwordID.text.toString().trim()


    create_acc_button.setOnClickListener{

        mAuth!!.createUserWithEmailAndPassword(email, 
        pwd).addOnCompleteListener(this
        ) { task: Task<AuthResult> ->
            if (task.isSuccessful){
                var user:FirebaseUser = mAuth!!.currentUser!!
                Log.d("User", user.email.toString())
            }else{
                Log.d("Error:", task.toString())
            }
        }
    }

Logcat:

In this way; email and pwd variables filled at first start. Your changes are not effect the variables.

You must move this lines into the clicklistener.

 //Create new User
var email = emailID.text.toString().trim()
var pwd = passwordID.text.toString().trim()

That worked beautifully. Thank you! So the problem was that the text was changing, but it was too late for the variables to be updated?

Exactly! In this way, you get texts when the user clicks on the button.

surround code with condition in button click

if (email != null || !email.isEmpty()) {
     //your positive code
} else {
     //your negative code    
}
