How to save String[] persistantly?

I am trying to save 

public   String [] myRemoteImages = {imageUrl,imageUrl2,imageUrl3,imageUrl4};

Persistantly.

I want to save the variables inside the array list, to a persistant storage so when the app is killed or destroyed. the URL's are still availible. But the url's will change about every month. I dont want to keep building up strings in a database over time.

So whats the best way to go about doing this?

EDIT: Something like...

    @Override
    protected void onSaveInstanceState(Bundle outState) {
        super.onSaveInstanceState(outState);
        Log.v("onSavedInstanceState", "Saved inside the bundle");
        SharedPreferences app_preferences = 
                PreferenceManager.getDefaultSharedPreferences(this);
        SharedPreferences.Editor editor = app_preferences.edit();
        editor.putString("URL1", imageUrl);
        editor.putString("URL2", imageUrl2)

    }

You have a number of data storage options available for Android, see list of options and overview here, with the simplest one being Shared Preferences. If you're just going to keep a handful of URLs around this is probably your best bet. The cleanup is up to you but can be very simple with a proper key/value pair naming strategy.

E.g.:

"URL1", "google.com"
"URL2", "stackoverflow.com"
...
"URLn", "nthwebsite.com"

where the keys (URLn) would remain the same but the web pages changed as necessary.

Or you can save it to SharedPreference if you do not want to use DB

Save it in the application's SQLite instance, and manually clean up or overwrite old URLs.
