To remove specific values: SharedPreferences.Editor.remove() followed by a commit()

To remove them all SharedPreferences.Editor.clear() followed by a commit()

If you don't care about the return value and you're using this from your application's main thread, consider using apply() instead.

You can write to Shared Preferences

SharedPreferences sharedPref = getActivity().getPreferences(Context.MODE_PRIVATE);
SharedPreferences.Editor editor = sharedPref.edit();
editor.putInt(getString(R.string.saved_high_score), newHighScore);
editor.commit();

and then read from Shared Preferences

SharedPreferences sharedPref = 
getActivity().getPreferences(Context.MODE_PRIVATE);
int defaultValue = getResources().getInteger(R.string.saved_high_score_default);
long highScore = sharedPref.getInt(getString(R.string.saved_high_score), defaultValue);

And also dont forget to get a handle 

SharedPreferences sharedPref = getActivity().getPreferences(Context.MODE_PRIVATE);

  • This is exactly all that is required to work with SharedPreferences, However, I would argue that you should tell people to use apply() instead of commit() just because – Saik Caskey Dec 05 '16 at 16:43
  • how do you hide the high score? its still visible in the location of the sharedpreferences in client's android – 0xDEADBEEF Dec 05 '16 at 16:44
  • I think this answer fits the bill, but you should post your solution and let the OP decide which is more useful to them – Saik Caskey Dec 05 '16 at 16:52
  • there is no "hide", you can overwrite if with Null. If you want to store the gold in a way it is not seen in the shared preferences then you must save it in a cloud. Is this the case? Do you want to prevent users to manipulate it? – Simon Schnell Dec 05 '16 at 16:53
  • yes I want to prevent users to manipulate it but in offline not with server – 0xDEADBEEF Dec 05 '16 at 16:58

something like this:

    SharedPreferences sp = getSharedPreferences("your sp name", Context.MODE_PRIVATE);
    sp.edit().remove("gold").commit();// remove gold
    sp.edit().clear().commit();//remove all
