How to get access to the Skype API on Android?

Question

Android

Good day.
I am making an application for android and the question arose of how to get the Skype API since they are closed. In general, you need to do something so that the user can add his Skype account to the android program and receive SMS and contacts, without calls.
The program will be done through the server, but if someone has a different solution, it may also work. The same goes for Viber and WhatsApp. If someone has seen the solution or knows it, then please unsubscribe.
