I'm using Firebase Authentication to sign up a user with a phone number and link that user with the email and password that he provides and if the authentication is successful the email and password should be saved in SharedPreferences and then the app should go to the maps activity, otherwise show a toast message.
When the maps activity starts it first checks some values in the shared preference, if these values exist the map will show up, otherwise, another activity should start.
this process is working very well but the problem is that the maps activity starts before shared preference commits the changes, and as the result maps activity will start another activity because it didn't find the values that are supposed to be saved from the registration activity.
the maps activity is the start point of the app, if you completed the sign-up process and restart the app again, then maps activity will check for these values and then show the map and that's what makes me say that committing the changes is very slow.
so the question is how to make sure that shared preferences committed the changes before moving to maps activity as the maps activity will check for them before showing the map

And here's how I'm checking for my values:
nurseId = PreferenceManager.getDefaultSharedPreferences(getBaseContext()).getString("nurseId", "");
name = PreferenceManager.getDefaultSharedPreferences(getBaseContext()).getString("name", "");
email = PreferenceManager.getDefaultSharedPreferences(getBaseContext()).getString("email", "");
password = PreferenceManager.getDefaultSharedPreferences(getBaseContext()).getString("password", "");
if (name.equals("") || nurseId.equals("") || email.equals("") || password.equals("")) {
startActivity(new Intent(this, WelcomeActivity.class));
finish();
}
