Question

I am retrieving about 7 URL’s from a service. I want to be able to write these URL’s some where and have my application read from them in another activity.

The thing that makes this tricky is the URL’s change every week. So i would need to overwrite the current URL’s. I don’t want to make the url’s stack up on top of each other where they never overrite and by the end of a month there are 24 unused URL’s.

What and how is the best way to do this?

Use SharedPreferences!

lol here is a sample:

public void SetUrls(String url[]) {
    SharedPreferences settings = getSharedPreferences("myPrefs", 0);
    SharedPreferences.Editor editor = settings.edit();
    editor.putString("url0", url[0]);
    editor.putString("url1", url[1]);
    editor.putString("url2", url[2]);
    editor.putString("url3", url[3]);
    editor.putString("url4", url[4]);
    editor.putString("url5", url[5]);
    editor.putString("url6", url[6]);
    editor.commit();
}

public String[] getUrls() {
    SharedPreferences settings = getSharedPreferences(DEALSPOTR_PREFS, 0);
    String url[] = new String[7];
    url[0] = settings.getString("url0", "default");
    url[1] = settings.getString("url1", "default");
    url[2] = settings.getString("url2", "default");
    url[3] = settings.getString("url3", "default");
    url[4] = settings.getString("url4", "default");
    url[5] = settings.getString("url5", "default");
    url[6] = settings.getString("url6", "default");
    return url;
}
