----- Initialization : ----- SharedPreferences pref = getApplicationContext().getSharedPreferences("MyPref", 0); // 0 - for private mode Editor editor = pref.edit(); ----- Storing Data : ----- editor.putBoolean("key_name", true); // Storing boolean - true/false editor.putString("key_name", "string value"); // Storing string editor.putInt("key_name", "int value"); // Storing integer editor.putFloat("key_name", "float value"); // Storing float editor.putLong("key_name", "long value"); // Storing long editor.commit(); // commit changes ----- Retrieving Data : ----- // returns stored preference value // If value is not present return second param value - In this case null pref.getString("key_name", null); // getting String pref.getInt("key_name", null); // getting Integer pref.getFloat("key_name", null); // getting Float pref.getLong("key_name", null)...
