android - Alternative for circles page indicator for many pages?

What's a good alternative for indicating that the user can swipe across the screen to get the next/previous item and/or showing the current position, considering that there are many pages (usually tens but sometimes upward of 100) -- so having a representation of all the pages wouldn't be possible.

Showing the page number like "2 of 22" seems a bit dull. Would combining that with the circles method be good or would it just be confusing?

EDIT: Just to clarify things (for my particular problem) , this is the 3rd level in a hierarchy : First you get choose from a list of categories, then you choose an item from a list of items in that category, then you see the details for this item and can swipe left or right to remove the need of going back to the second list.
