How to transfer arbitrary data to an application downloaded from Google Play?

Question

Android

Let's say we have an Android app. We register on the site and receive a link to download the application from Google Play. How can we transfer data so that the downloaded application is already logged in under our account to the site where we previously registered? Is it possible to do something similar in the App Store?

In ios, you can indirectly:
1) submit a standard application to the app store. The application must be registered to open a special url, for example app://blahblah. More details from the developer under ios.
2) when you first launch the application, it opens a special page/link on your site. This page will need to redirect back to app with the link app://<data to be passed to the app>.
3) the application processes the link and pulls out the necessary data, for example, login / token.
This will only work if the user has an active session in the safari browser, otherwise it will not be clear whose token to give. Well, for the user it will look like the launch of the application --> the browser immediately opens --> again throws it into the application. A similar mechanism is used in facebooke.
