In my

    public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {}

DBHelper function(implementing SQLite open helper) I provide sql queries to modify as per my new version.

But I also want to clear some of my Shared Preferences Details on upgrade.
But Opening sharedPreferences for editing requires Context object, how do I provide it here..?
