Thing that you could do is to create a PreferenceActivity like :

public class Prefs  extends PreferenceActivity  {   
    @Override
    public void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        addPreferencesFromResource(R.xml.preference);
    }

}

In res/xml folder add preference.xml with this content :

<?xml version="1.0" encoding="utf-8"?>
<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android" >

    <PreferenceCategory android:title="General" >
        <CheckBoxPreference
            android:key="notification"
            android:summaryOff="You will not receive any notification"
            android:summaryOn="Notifications are sent to your device"
            android:title="Get notification" />
    </PreferenceCategory>

</PreferenceScreen>

In your code you can do now : 

SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(context);
Boolean sendNotification = prefs.getBoolean("notification", false);

Use SharedPreferences

Save your settings:

SharedPreferences prefs = getSharedPreferences("myprefs",Context.MODE_PRIVATE);
SharedPreferences.Editor editor = prefs.edit(); 
editor.putString("email", "[email protected]"); 
editor.putString("name", "Albert"); 
editor.commit();

Retrieve them:

SharedPreferences prefs = getSharedPreferences("myprefs",Context.MODE_PRIVATE);   
String email = prefs.getString("email", "[email protected]");

There's actually multiple ways to persist changes. The Android documentation covers all of them in more detail, but essentially these are the five ways. Easiest is SharedPreferences, probably.

Shared Preferences

Store private primitive data in key-value pairs.

Internal Storage

Store private data on the device memory.

External Storage

Store public data on the shared external storage.

SQLite Databases

Store structured data in a private database.

Network Connection

Store data on the web with your own network server.

You need to store these settings within the Database. On how to use this see Using Databases

Use SharedPreferences. You can put key value pairs and retrieve when needed .
