Question

How to make Preferences items with programmatically filled values (like: Version, Model number…)?

Answer 1

You can set the preferences within you code, and check if it already is filled before you fill it. As long as you do not give users access to change this information, all they can do is “clear local data”, which will cause the program to re-fill the data if you do it right.

I use this technique to store unique IDs for the device, who is logged in, etc. The user doesn’t even (and should never) know what I keep track of, all they know is they have a smooth program that does what they need it to do.

Example:

SharedPreferences settings = context.getSharedPreferences("preferanceName", 0);
SharedPreferences.Editor editor = settings.edit();
int value = foo;
editor.putInt("ValueToStore", value);
editor.commit();
