Answer 2

Using this ...

protected void onResume(){
    super.onResume();
    SharedPreferences settings = getSharedPreferences(PREFS_COUNT, 0);
    count = settings.getInt("count", count);
}
protected void onPause(){
   super.onPause();


  SharedPreferences settings = getSharedPreferences(PREFS_COUNT, 0);
  SharedPreferences.Editor editor = settings.edit();
  editor.putInt("count", count);
  editor.commit();
}
