SqlCount

[dmfs]

If a ContentProvider uses an SQL backend, another method to get the row count of a table exists:

Cursor c = view.withProjection("Count(*)").rows(EmptyUriParams.INSTANCE, mPredicate, absent());
c.moveToFirst();
long count = c.getLong(0);

Of course that fails if a ContentProvider doesn't use an SQL backend. So the question is, is it worth it?
How much speed do we gain? We probably should test this with a reasonably large table first and compare it against #101.

Just a question, do you expect RowCount/SqlCount to be used in production code, or only in tests?

[dmfs]

It's meant to be used in production code. For now this is very low priority though. RowCount will do well in most cases.
