Intent filters can match on the data of an intent through the <data> tag. When multiple tags are present, they act as a boolean OR, intended if you want to match multiple data types. When a boolean AND is required, the attributes should instead be added to a single <data> tag. Two of our intent filters try to match ".pbw" and ".pbz" files. These both start with a single match on the "content" schema, followed by a match on the "*/*" MIME type, and finally a path filter for the file type in question. By virtue of being boolean OR, this meant that both filters would match every possible URL. Combine the attributes in a single data tag to turn it into a boolean AND for both of these filters.

I don't know about pbz, but pbw is a zip archive, so you can use that mime type for it
