Getting Preferences API working on both Android and PC
in
Android Processing

Hi.
I'd like to save user preferences from a sketch running either on a PC or an Android phone, using the same code in as standard "Java-way" as possible.
Ideal candidate for my purposes seems to be the java.util.prefs.Preferences class. So, I wrote a little test script to see if it's working in processing:
This program outputs an increasing number each time it is executed - on a PC. On Android, the default value (0) is always shown.
Are there any additional steps required to get this working on Android? Permissions to be requested?
Are there any alternatives for saving name - value pairs on both platforms?
Thanks for answers.

- String prId = "counter";
- Preferences prefs = Preferences.userNodeForPackage(this.getClass());
- int counter = prefs.getInt(prId, 0);
- println(counter);
- prefs.putInt(prId, 1+counter);
