Here's a static wrapper I implemented to get and set properties real
easy
package gubatron.android.util;
import java.util.Arrays;
import android.content.Context;
import android.content.SharedPreferences;
import android.content.SharedPreferences.Editor;
/**
* Convenience class to get or set preference values without dealing
with Android's SharedPreferenes and the editor.
* Licensed under LGPL.

* @author gubatron

* Examples:
*
* PrefUtils.setString(key, value)
*
* String value = PrefUtils.getString(key);
* PrefUtils.getString(key, defaultValue);
