Help with login screen!

I have been following the build a self destructing messaging app tutorial. I recently switched to Backendless instead of using Parse. I keep getting an error code: 3003. (Invalid Login or password). It gives me this message no matter what I input into the editTexts. Here is my code:

import android.app.AlertDialog; import android.content.Intent; import android.os.Bundle; import android.support.v7.app.AppCompatActivity; import android.support.v7.widget.Toolbar; import android.view.View; import android.widget.Button; import android.widget.EditText; import android.widget.TextView;

import com.backendless.Backendless; import com.backendless.BackendlessUser; import com.backendless.async.callback.AsyncCallback; import com.backendless.exceptions.BackendlessFault; import com.jordanpeterson.textly.R; import com.jordanpeterson.textly.utils.Constants;

public class LoginActivity extends AppCompatActivity { protected EditText mUsername; protected EditText mPassword; protected TextView mSignUpTextView; protected Button mLoginButton;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_login);
    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
    setSupportActionBar(toolbar);
    Backendless.initApp(this, Constants.APPLICATION_ID, Constants.ANDROID_SECRET_KEY, Constants.VERSION);

    mUsername = (EditText) findViewById(R.id.usernameLoginField);
    mPassword = (EditText) findViewById(R.id.passwordLoginField);
    mSignUpTextView = (TextView) findViewById(R.id.signUpTextView);
    mSignUpTextView.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Intent loginIntent = new Intent(LoginActivity.this, SignUpActivity.class);
            startActivity(loginIntent);
        }
    });
    mLoginButton = (Button) findViewById(R.id.loginButton);
    mLoginButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            String username = mUsername.getText().toString();
            String password = mPassword.getText().toString();

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

            if (username.isEmpty() || password.isEmpty()) {
                AlertDialog.Builder builder = new AlertDialog.Builder(LoginActivity.this);
                builder.setMessage(R.string.login_error_message)
                        .setTitle(R.string.login_error_title)
                        .setPositiveButton(android.R.string.ok, null);
                AlertDialog dialog = builder.create();
                dialog.show();
            } else {

                Backendless.UserService.login(username, password, new AsyncCallback<BackendlessUser>() {
                    @Override
                    public void handleResponse(BackendlessUser backendlessUser) {
                        Intent intent = new Intent(LoginActivity.this, MainActivity.class);
                        intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
                        intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK);
                        startActivity(intent);
                    }


                    public void handleFault(BackendlessFault fault) {
                        // an error has occurred, the error code can be retrieved with fault.getCode()
                        AlertDialog.Builder builder = new AlertDialog.Builder(LoginActivity.this);
                        builder.setMessage(fault.getCode())
                                .setTitle(R.string.error_title)
                                .setPositiveButton(android.R.string.ok, null);
                        AlertDialog dialog = builder.create();
                        dialog.show();
                    }
                });

            }
        }
    });


}

}
