Anybody got any ideas? I thought I had it figured out with the database but that didn't work.
It seems that either my naming of the CONTENT_URI or something to do with that is wrong or else a database/table for the settings never actually gets created? if theres no data there for the content provider would I get that error? Or is it actually something to do with the CONTENT_URI?
