Trouble saving high score in android app

Question

I searched online and people are doing this:

SharedPreferences prefs = this.getSharedPreferences("myPrefsKey", Context.MODE_PRIVATE);
int oldScore = prefs.getInt("key", 0);  
if(newScore > oldScore ){
   Editor edit = prefs.edit();
   edit.putInt("key", newScore);
   edit.commit();
}

But I want to use the first line in a class other than the class that extends Acitivity (it seems the this.getSharedPreferences method won't work otherwise). How can I do this?

Are you working with activity or fragment ? – Hiren Patel May 31 '15 at 05:09 — Hiren Patel, May 31 '15 at 05:09

You'll have to pass a Context to the method or the class you want to use getSharedPreferences() in like so:

public void updateHighScore(Context context, int newScore) {
  SharedPreferences prefs = context.getSharedPreferences("myPrefsKey", Context.MODE_PRIVATE);
  int oldScore = prefs.getInt("key", 0);  
  if(newScore > oldScore) {
   Editor edit = prefs.edit();
   edit.putInt("key", newScore);
   edit.commit();
  }
}

If you really need to, you can use getApplicationContext() to provide a context accessible anywhere in the application.

For more informations check out this question 'What is context in Android?'.

I used getApplicationContext() as my solution. Thanks. – Fuad May 31 '15 at 23:42 — Fuad, May 31 '15 at 23:42
