How to use one time domain name in android?

Question

I have a RESTful web-service, I am retrieving a data to android device

So here My ip address/Doamin name may change like.. 192.168.0.1 or1-255 etc or It may be www.stackexchange.com or www.stackoverflow.com

Like my data will be stored in 192.168.0.1/rst/api/login or www.stackoverflow.com/rest/api/sitemview

So to over come this I want to use domain name as One time when i install application

in my application I have other pages like Login,display list-view, Single ItemView.

So this domain name should stored in device and pass to other activities every time when I use.

I used shared preferences like

public static void savePreferences(Context ctx, String key, String value) {
    SharedPreferences sharedPreferences = PreferenceManager
            .getDefaultSharedPreferences(ctx);
    SharedPreferences.Editor editor = sharedPreferences.edit();
    editor.putString(key, value);
    editor.commit();
} 

so when they load

public static Object loadSavedPreferences(Context ctx, String key) {
    SharedPreferences sharedPreferences = PreferenceManager
            .getDefaultSharedPreferences(ctx);
    return sharedPreferences.getString(key, "");
}

So here My problem is that This one time value is not permanent when ever I force close or Restart devise that passing value is not working

Any suggetion

If your domain name fixed, use below code.

public class WS{
   public static final String domain="http://blah.ws";
}

Access it in each activity with

String apiPath=WS.domain+your_rest_path;
