what is the Best way to use shared preferences between activities

Question

I have a user preference in my app, which gets used by different activities. I would like to know the best way to utilize those preferences between different activities in m

Answer 1

You can use this way and declare same variables with same name in all activites where you want to use.

  public static final String PREFS_NAME = "MyPrefsFile";
  static SharedPreferences settings;
  SharedPreferences.Editor editor;
  int wordCount;

 public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    settings = getSharedPreferences(PREFS_NAME, 0);
    editor = settings.edit();

    wordCount = settings.getInt("wordCount", 4); 

  }

Here initially wordCount will give 4; And when you edit wordCount and want to store again

  editor.putInt("wordCount", 6);
  editor.commit();

You have to declare this same variables in activities where you want to use shared preferences. And its better you call getSharedPreferences in every activity.

I don't think that passing that preference in intent will work.
