Propagation of corporate settings how to do?

Question

Android

There is a note app. It can be both in the cloud and corporate. What are the best practices for propagating the settings connection string?

I want as little movement as possible.

What comes to mind.
1. A general application in the market, in the settings it is possible to drive in the address of the endpoint
2. The handler in the application that processes the link according to the protocol, the links are respectively sent by SMS or mail.
3. custom build (I don't like this option the most)

What do you recommend?

Answer 1

2. JSON array returned by a POST request to the server, which contains all the necessary settings and is written to the necessary variables in SharedPreferences and stored there until a second request...
