APP-IN-BILLING | Kivy has a permission?

[berk berk]

Guys, I create a button, and if user press on it, I have to display Google Play Store --in-billing payment for in app price items. (Like gem 1$ on mobile games) But need some permissions for app-in-billing(in buildozer) need code piece to popup payment.

Is there a step or document for doing it?
(look below picture)

Not clear what you want, an app/Buildozer just passes the permissions you specify to Android.

The list is here https://github.com/Android-for-Python/Android-for-Python-Users#app-permissions

You see photo that i sent on top. I mean; You want to create in app price. So There are buttons these representing premium elements. These elements are paid. User clicks buttons then Google Play Store payment opens. that's all. 

First: You need the application on Google Play Store
Second: You must add in app permission(Android permission) "com.android.vending.BILLING" That's okay I'll add in buildozer.spec
Third: You must take specific code Google Play Console that representing paid buttons(elements).
Fourth: Then If user clicks on button, you must define button event to open Google Play Store payment.

Where is my problem?
Now I add second steps. I completed 1st step also. But I didn't other steps following after 2nd steps. 
How I define event that click buttons opens  Google Play Store payment? how specific code put where?

I did not find the steps in Kivy for it.
Thanks

I don't know of any examples.
I expect it would be easiest to implement this in Java then call your Java from Python.
