I am using Firebase User Authentication, Email/Password method. I want to test whether i can change my email and i keep getting email invalid when it is correct and when i keep pressing change which is the button to start the change email method i get this.

FirebaseError: There was an exception while performing the request: Unexpected character ('<' (code 60)):expected a valid value(number,String,array,object,'true','false' or 'null')

Can anyone know how to solve this problem ?

public class ChangeEmail extends BaseActivity implements View.OnClickListener {

EditText Password, CurrentEmail, NewEmail;
String FirebaseUserNewEmail, FirebasePassword, FirebaseUserCurrentEmail;
Button buttonDone;
public static final String DEFAULT = "N/A";
String username;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    /**
     * Adding our layout to parent class relative layout.
     */
    getLayoutInflater().inflate(R.layout.changeemail, RelativeLayout);

    CurrentEmail = (EditText) findViewById(R.id.CurrentEmail);
    NewEmail = (EditText) findViewById(R.id.NewEmail);
    buttonDone = (Button) findViewById(R.id.buttonDone);
    buttonDone.setOnClickListener(this);
    // Password - Edit Text
    Password = (EditText) findViewById(R.id.Password);
    // Make text style stay the same / as default
    Password.setTypeface(Typeface.DEFAULT);
    // Make password confidential.
    Password.setTransformationMethod(new PasswordTransformationMethod());

    SharedPreferences prefs = getSharedPreferences("project", 0);
    username = prefs.getString("keyusername", DEFAULT);

    SharedPreferences settings = PreferenceManager.getDefaultSharedPreferences(ChangeEmail.this);
    username = settings.getString("keyusername", DEFAULT);

    setTitle("Settings");
