    };

I have the error 03-20 00:46:02.120: E/AndroidRuntime(14847): java.lang.NullPointerException for all getResources line ?

Thanks

getResources() is a method of Context, so you can only do it like that in a class instance which subclasses Context, like an Activity.

And actually you may want to look into String Array resources: http://developer.android.com/guide/topics/resources/string-resource.html#StringArray
