Proper communication

I'm wondering which communication method use in my app. There will be python server displaing data from website and from android app. That is easier part where I will use REST. But then I need communication back to android app from server and also from server to second android app. I thought about sockets. Is it proper way? Mayby REST isn't good choice also?

Give my some tips please. Thank you on advice.

Using sockets can be a suitable method for bidirectional communication between your Python server and Android apps.

But you can consider `the below list of communication methods for your app:

• REST for data retrieval.
• WebSocket for real-time bidirectional communication.
• Push Notifications for server-to-app updates.
• Long Polling with REST for simple real-time updates.
• MQTT for publish-subscribe communication.

To say, WebSocket is often a good choice for real-time communication,
