Question

I am new to android development. Is there a way to extends class from another package? I am trying to get the shared preferences from another package, although I am able to access the shared preferences between classes within the same package. However, at different packages, I have no idea how I should do editer.commit() or edit the shared preferences that is in another package. Please help.

Answer 1

try this code

to put a string to sharedpreference

    SharedPreferences USERNAME_and_PASSWORD;
            SharedPreferences.Editor editor;

USERNAME_and_PASSWORD = getSharedPreferences(Shared_preference_key,
                MODE_PRIVATE);
        editor = USERNAME_and_PASSWORD.edit();
                editor.putString(user_name_key, userName);
                editor.commit();

to get a string from shared preference

    SharedPreferences USERNAME_and_PASSWORD;
 USERNAME_and_PASSWORD = getSharedPreferences(Shared_preference_key,
                    MODE_PRIVATE);
     USERNAME_and_PASSWORD = getSharedPreferences(Shared_preference_key,
                        MODE_PRIVATE);
    String Return_Password = USERNAME_and_PASSWORD.getString(pass_word_key,
                    "Guest");
