invalid email

Basically, whatever I type in the username in the signing up page, pops an error message saying 'invalid email' but when I type in a username in form of an email, I am able to sign up. I can't seem to find what the problem is. I followed exactly as the tutorial video. Below is some codes where I think it is relevant.

SignUpActivity.java 
protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_sign_up);

        mUsername = (EditText)findViewById(R.id.usernameField);
        mPassword = (EditText)findViewById(R.id.passwordField);
        mEmail = (EditText)findViewById(R.id.emailField);
        mSignUpButton = (Button)findViewById(R.id.signupButton);
        mSignUpButton.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {
                String username = mUsername.getText().toString();
                String password = mPassword.getText().toString();
                String email = mEmail.getText().toString();

                username = username.trim();
                password = username.trim();
                email = username.trim();

                if (username.isEmpty() || password.isEmpty() || email.isEmpty()) {
                    AlertDialog.Builder builder = new AlertDialog.Builder(SignUpActivity.this);
                    builder.setMessage(R.string.signup_error_message)
                        .setTitle(R.string.signup_error_title)
                        .setPositiveButton(android.R.string.ok, null);
                    AlertDialog dialog = builder.create();
                    dialog.show();
                }
                else {
                    // create the new user!
                    ParseUser newUser = new ParseUser();
                    newUser.setUsername(username);
                    newUser.setPassword(password);
                    newUser.setEmail(email);
                    newUser.signUpInBackground(new SignUpCallback() {

                        @Override
                        public void done(ParseException e) {
                            if (e == null) {
                                // success!
                                Intent intent = new Intent(SignUpActivity.this, MainActivity.class);
                                intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
                                intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK);
                                startActivity(intent);
                            }
                            else {
                                AlertDialog.Builder builder = new AlertDialog.Builder(SignUpActivity.this);
                                builder.setMessage(e.getMessage())
                                    .setTitle(R.string.signup_error_title)
                                    .setPositiveButton(android.R.string.ok, null);
                                AlertDialog dialog = builder.create();
                                dialog.show();

                            }


                        }
                    });
                }

            }
        });
    }

I had to run it in my own project and log the values to see the error. Notice anything wrong with these 3 lines?

username = username.trim();
password = username.trim();
email = username.trim();

    I see. So shouldn't it be

username = username.trim();
password = password.trim();
email = email.trim();

this? it makes sense now.

How silly of me. Sorry for not fully concentrating. I will focus harder and work harder. I promise Ben.

Thank you so much for personally helping me.

I am a big fan of yours.

It almost sounds like your wires are crossed, in that somewhere the email and username fields are getting flipped or assigned incorrectly. Can you paste in your whole layout XML file? The username field looks okay, but perhaps the EditText for the email address accidentally has the same ID of "usernameField"?
