I wrote one that goes out to the internet and fetches data.

In my code, I use the 'String[] projections' to create my own Cursor
implementation. I make a subclass of 'Cursor', an instance of which
will be returned by my ContentProvider's query method. The constructor
of this Cursor-subclass takes the 'projections' as an input parameter
and the subclass uses it to correctly implement the method
'getColumnIndex(String columnName)'.

I don't know about MatrixCursor, though. I can't help you there :)

If 'projections' is null, I simply pass a String-array to this
constructor holding all possible column-names for my ContentProvider.
