Android - Firebase - The email address is badly formatted

Question

Aim

Allow users to register their preferred display name, home address, email, and password by utilizing Firebase Authentication (Email and Password)

Java Class

import android.content.Intent;
import android.support.annotation.NonNull;
import android.support.design.widget.TextInputLayout;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.widget.Button;
import android.widget.Toast;

import com.google.android.gms.tasks.OnCompleteListener;
import com.google.android.gms.tasks.Task;
import com.google.firebase.auth.AuthResult;
import com.google.firebase.auth.FirebaseAuth;
import com.google.firebase.auth.FirebaseAuthException;

public class RegistrationActivity extends AppCompatActivity {

    private TextInputLayout jRegisterName;
    private TextInputLayout jRegisterAddress;
    private TextInputLayout jRegisterEmail;
    private TextInputLayout jRegisterPassword;
    private Button jRegisterRegBtn;

    //Firebase
    private FirebaseAuth mAuth;


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_registration);

        //Firebase Auth
        mAuth = FirebaseAuth.getInstance();

        jRegisterName = (TextInputLayout) findViewById(R.id.registerName);
        jRegisterAddress = (TextInputLayout) findViewById(R.id.registerAddress);
        jRegisterEmail = (TextInputLayout) findViewById(R.id.registerEmail);
        jRegisterPassword = (TextInputLayout) findViewById(R.id.registerPassword);
        jRegisterRegBtn = (Button) findViewById(R.id.registerRegBtn);

        jRegisterRegBtn.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {

                String userDisplayName = jRegisterName.getEditText().toString();
                String userHomeAddress = jRegisterAddress.getEditText().toString();
                String userEmail = jRegisterEmail.getEditText().toString().trim();
                String userPassword = jRegisterPassword.getEditText().toString().trim();

                registerUser(userDisplayName, userHomeAddress, userEmail, userPassword);

            }

            private void registerUser(String userDisplayName, String userHomeAddress, String userEmail, String userPassword) {
                mAuth.createUserWithEmailAndPassword(userEmail, userPassword).addOnCompleteListener(new OnCompleteListener<AuthResult>() {
                            @Override
                            public void onComplete(@NonNull Task<AuthResult> task) {
                                if (task.isSuccessful()) {
                                    Intent intentMain = new Intent(RegistrationActivity.this, MainActivity.class);
                                    startActivity(intentMain);
                                    finish();
                                }else if(!task.isSuccessful()){
                                    FirebaseAuthException e = (FirebaseAuthException )task.getException();
                                    Toast.makeText(RegistrationActivity.this, "Failed Registration: "+e.getMessage(), Toast.LENGTH_SHORT).show();
                                    return;
                                }
                            }
                        });
            }
        });

    }
}

Problem

After the user has entered the input such as

Name : JohnSmith

HomeAddress : 18 King Street

Email : [email protected]

Password : 123456789pass

The user fails to register and the message below prompts out

"Failed Registration: The email address is badly formatted"

@YCF_L I mean the message that prompts out after I register is "Failed Registration: The email address is badly formatted". I'll edit my question — The Employee 123
An error prompts out Incompatible Types as the in the XML file, I am using TextInputLayout. I can only use "getEditText()". Should I post the XML codes? — The Employee 123

Check your inputType on the xml file. There is 3 types of inputs on email.

android:inputType="textWebEmailAddress"
android:inputType="textEmailAddress"
android:inputType="textEmailSubject"
