Notification manager & Forms

In my android project, I have written code to add notification to Android's notification area. It works.

However, on click on the notification, I want to show a page which is part of the Forms project.

In Android project, I would need to create a stack builder and specify the class name of the android activity, like below

Intent resultIntent = new Intent(this, ResultActivity.class);

But since my page is in Forms project, the approach may be different. If I directly give the Form's Page class here, it doesn't work.

Can anyone help me with how to achieve this?
