Can and Should we commit SharedPreferences on NON UI thread, if yes how ?

I am making an app and it has to save and extract data at runtime, and sharedPrefrences is making my animations lag. so is there a way to save and retrieve data on NON-UI thread.

Or is there any problem with my method

    private void difficultyHandler(){
    sharedPref = this.getSharedPreferences(getString(R.string.lScore),Context.MODE_PRIVATE);
    difficulty =  sharedPref.getInt(getString(R.string.difficultyController),0);
    if (times >= 1){

        long latestScore1 = sharedPref.getLong(getString(R.string.lScore1),0);
        long latestScore2 = sharedPref.getLong(getString(R.string.lScore2),0);
        editor = sharedPref.edit();
        editor.putLong(getString(R.string.lScore1),score);
        editor.putLong(getString(R.string.lScore2),latestScore1);


        if(latestScore1 >= 60 && latestScore2 >=60 && latestScore1 < 140 && latestScore2 <140){
            difficulty = 2;
        }else if (latestScore1 < 60 && latestScore2 < 60){
            difficulty = 1;
        }else if(latestScore1 >= 140 && latestScore2 >=140){
            difficulty = 3;
        }
        editor.putInt(getString(R.string.difficultyController),difficulty);
        editor.commit();
    }

there is one more method like this.

is there a way to put the entire method on another thread.

basically i want to solve the problem of lagging.

SharedPreferences are cached. The first time you try accessing a given SharedPreferences (e.g., getSharedPreferences()), there will be disk I/O. You are welcome to do this work on a background thread, sometime in advance of when you need the preferences.

You can call apply(), rather than commit(), to persist changes to the SharedPreferences on a framework-supplied background thread.
