DataBinding: cannot find symbol class

I've got a problem with databinding in android. Above are xml file and activity class:

activity_main.xml ( the binding is in android:enabled="@{loginInfo.existingUser}")

 <layout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    xmlns:app="http://schemas.android.com/apk/res-auto">

  <data>
  <variable
   name="loginInfo"
    type="com.example.android.loginapplication.LoginInfo"/>
  </data>

<LinearLayout
android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    android:padding="16dp">

    <RadioGroup
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical">

        <RadioButton
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="@string/new_customer"
            android:enabled="@{loginInfo.existingUser}"/>

        <RadioButton
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="@string/i_have_a_password"/>
    </RadioGroup>

    <EditText
    android:id="@+id/password"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:inputType="textPassword"/>
  </LinearLayout>

  </layout>

LoginInfoActivity.java

public class LoginInfoActivity extends AppCompatActivity {

private LoginInfo loginInfo;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    LoginInfoBinding binding = DataBindingUtil.setContentView(
            this, R.layout.activity_main);


    binding.setLoginInfo(loginInfo);
}
}

it can't find generated class LoginInfoBinding in LoginInfoActivity...

is the xml correct? Or it depends by other things?

The binding class is named after the layout resource by default. Your layout resource is activity_main.xml, so the binding is ActivityMainBinding.
