What methods exist for centralized application parameter configuration?

Common methods for centralized configuration of Android application parameters include:

• SharedPreferences — for storing simple key-value pairs, suitable for user settings.
• Configuration files (e.g., JSON, XML) — can be stored in assets or raw resources and loaded at app startup.
• Using BuildConfig or gradle.properties — for parameters set at build time.
• Dependency Injection (e.g., Dagger, Hilt) — allows centralized management of configuration and dependencies.
• Remote Config (Firebase Remote Config) — for dynamically changing parameters without updating the app.

Example of using SharedPreferences:

val prefs = context.getSharedPreferences("app_settings", Context.MODE_PRIVATE)
prefs.edit().putString("api_url", "https://api.example.com").apply()

val apiUrl = prefs.getString("api_url", "https://default.example.com")
