I am developing one application for Android.
As we all know, the Facebook SDK provides functionality for sending a request to other users using the Request dialog box.
https://developers.facebook.com/docs/android/send-requests
I mentioned the link above that says how we can send a request to other facebook users, and in response this request will be shown to the user in their profile as a notification.
So my question is: is there any API for Google Plus that I can use to send any request from the Android application to Google Plus, and just like facebook, my request will be shown to users of this Google Plus profile
I have already used the Google Plus API and OAuth2.0.
I am new to using the API, if possible, then please give me an example as well.
Edit: -
I found the following link stating that it does not work on Google, please check out the following link.

Edit: -
Create a notification in Google Plus without posting to any profile.
Here, photography is just an example of a game.

But in google plus.
