There should be a 'compact' method on the Database class. (I'm not very 
familiar with the Android/Java API.)

For replication -- If there were no trace left of a deleted document, then if 
you replicated from another database that contained that document, it would 
reappear. The deletion is a permanent record that you deleted the doc. And if 
you replicate to another database, the deletion will propagate.

(The details: deleting a document is really just adding a new revision whose 
contents consist only of a "_deleted":true property.)
