Payment Integration for Android App

I have a android app on the name of "Best Bhav" listed on google play store. Currently instamojo is linked to my app for payment gateway services but I want to remove it and instead add [login to view URL] as my payment gateway partner.

I need the following changes:

1. Add [login to view URL] as payment gateway service in place of [login to view URL] and make the payment flow fully functional.

2. Set layout of payment window interface of my app as given in the screenshots attached. (Refer Bigbasket App's payment page for reference)

My App Link: [login to view URL]
