Accessing Current SharedPreferences Data from Background Services - android-studio

Question

My app uses a countdown timer in the background in a class that extends Services. The background running service is designed to access the Sharedpreferences data of the app. During the countdown, a particular integer in the Sharedpreferences changes value and the updated value is expected to be accessed in the onFinish() call of the countdown timer. The problem now is that the Service don't read the updated valued from the Sharedpreferences but rather returns the initial value at the point the background service started.
I saw somewhere that the solution to the problem is to use
PreferenceManager.getDefaultSharedPreferences()
instead of getSharedPrefences to be able access the current SharedPreferences value. I implemented this recommendation but the problem persist.
Please somebody should help me out because trying to figure out this is taking too much of my time.
My code is here:
public class BroadcastService extends Service {
DatabaseHelperClass myDatabase = new DatabaseHelperClass(this);

Long timeLeftInMiliseconds;

public static final String COUNTDOWN_BR = "com.cenitscitech.www.etimebook.countdown_br";
Intent bi = new Intent(COUNTDOWN_BR);
CountDownTimer cdt = null;
#Override
public void onCreate() {
super.onCreate();
defaultSharedPreferences = PreferenceManager.getDefaultSharedPreferences(this);
defaultSharedPreferencesEditor = defaultSharedPreferences.edit();
sharedPreferences = getSharedPreferences("setTime", MODE_PRIVATE);
//staffSignedIn = getSharedPreferences("present", MODE_PRIVATE);
//countSignIn = staffSignedIn.getInt("max", 0);
//staffEditor = staffSignedIn.edit();
simpleDateFormatII = new SimpleDateFormat("MMM EEE dd, yyyy HH:mm");
Log.i(TAG, "Starting timer in broadcast receiver...");
Log.i(TAG, "max Count Obtained onBroadcastCreate: "+defaultSharedPreferences.getInt("max", 0));
}
#Override
public void onDestroy() {
//cdt.cancel();
Log.i(TAG, "Timer in broadcast receiver cancelled");
super.onDestroy();
}
#Override
public int onStartCommand(Intent intent, int flags, int startId) {
timeLeftInMiliseconds = intent.getLongExtra("timeLeft", 0L);
cdt = new CountDownTimer(timeLeftInMiliseconds, 1000) {
#Override
public void onTick(long millisUntilFinished) {
SharedPreferences defaultShared = PreferenceManager.getDefaultSharedPreferences(getApplicationContext());
Log.i(TAG, "Countdown seconds remaining: " + millisUntilFinished / 1000);
/*bi.putExtra("countdown", millisUntilFinished);
sendBroadcast(bi);*/
}
#Override
public void onFinish() {
SharedPreferences defaultSharedPreferences2 = PreferenceManager.getDefaultSharedPreferences(getApplicationContext());
countSignIn = defaultSharedPreferences2.getInt("max", 0);
Log.i(TAG, "Timer finished");
