How to use shared preference data in different classes in android?

Question

Using shared preferences I saved data in one of the activity Now I want to use that data in another activity how to do that?

Answer 1

Create a sharedPreference where you want to add shared data. A little example of code like this:

SharedPreferences prefs = this.getSharedPreferences("CONSTANT_FILE_NAME",
                Context.MODE_PRIVATE);

SharedPreferences.Editor editor = prefs.edit();
                editor.putBoolean("isPaid", true);
                editor.commit();

And to retrieve that shared data use this code:

SharedPreferences prefs = this.getSharedPreferences("CONSTANT_FILE_NAME",
                    Context.MODE_PRIVATE);
prefs.getBoolean("isPaid",false);
