Access Shared Preferences from Different Activity (Android)

Question

When you establish a shared preference such as below...

public static final String PREFS_HI = "MyPrefsFile";

Can you access it from other activities just like you would normally do?

SharedPreferences settings = getSharedPreferences(PREFS_HI, 0);

Or is there something unique that you must do to access the preferences?

Answer 1

I would store your shared preferences name (What you are calling PREFS_HI) in the resources xml file (strings.xml). Then you can just use getSharedPreferences(getResources().getString(R.string.sharedPrefs)). Your solution works as well, though. (And the performance may be slightly better in your version.)

Answer 2

Figured this out myself. I just used global variables and stored sharedpreferences inside there. When another activity wanted to access the preferences, it would simple access a global variable.
