How do I use sharedPreferences in Android?

Question

I have an Android app which in one of the activities the user check one of the radio buttons. I want to save the user's choice and use its value in another activity.

This is pretty basic and explained in [the documentation](https://developer.android.com/guide/topics/data/data-storage.html#pref) — Gerald Schneider, Nov 21 '14 at 16:44

To store

SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(); 
prefs.edit().putBoolean("KEY", your_boolean).commit();

To retrieve

Boolean your_boolean = prefs.getBoolean("KEY", false);

You can use shared preference for saving the values.

For Saving value into SharedPreferences use below code

SharedPreferences.Editor editor = getApplicationContext().getSharedPreferences(
                        "SHARED_PREF", MODE_PRIVATE).edit();
                editor.putString("radio_value", value);
                editor.commit();

For Retriving value from SharedPreferences use below code

  SharedPreferences prefs = getApplicationContext().getSharedPreferences(
            "SHARED_PREF", MODE_PRIVATE);
    String storedValue = prefs.getString("radio_value","");
