Configuration file in Android. Does that exist?

I have some configuration I want to save it in my Android application and read it whenever I need , for instance, the开发者_如何学编程 server URL that it should try to access like that.

Is there any similar mechanism like web.config in ASP.NET available in Android?

A central configuration file that can be set up manually and then read by the application? Any help would be appreciated!

We use a .properties file in assets folder. It works out very well for us as we support multiple carriers with this, write to it (in case some values, sent from server, need to change. This is done at app start time, thus making our code configurable from server).

You can throw things like that into your strings.xml file. But, since you can't actually modify these values in real-time (since it's a distributed application rather than running on a server), throwing it into a constants class is quite acceptable.

Use Shared Preferences.
Here's a link Shared Preferences

You can use sq lite database files for it. You have a native API to read and write those and on top of that a command line tool. If you want to create an XML file instead, then it's no different than any other xml file (unless you are thinking about the Shared Preferences, which use an xml format to save the data, but I believe it's not the best API for your application).

I was stumped on this too, but came across Managed Configurations in the Android documentation.

Managed configurations, previously known as application restrictions, allow the enterprise administrator to remotely specify settings for apps. This capability is particularly useful for enterprise-approved apps deployed to a managed profile.

It allows you to set a default value in case you rather not getting into the enterprise admistration business but leaves that option open for the future.

There is a caveat. This only works if your app is registered for EMM. Otherwise you will retrieve an empty map of restrictions.
