This is becoming frustrating.
When you ask CC to open a book, it:
- looks up the mimetype for the extension using Android's MimeTypeMap. If this returns something, then use it totally unmodified.
- If MimeTypeMap returns nothing, then look up the mimetype in CC's internal table and use that.
- If CC's internal map returns nothing, then show a dialog saying that CC doesn't know what to do.
- Given a non-null mimetype, ask Android to provide a list of "intents" (applications) that can handle that mimetype, and show them to the user. If Android returns an empty list, show a dialog to the user.
Couple this with your experience, then one of the following must be true:
- The mimetype map for your tablet is returning an incorrect value for epub. What "incorrect" means in this instance is unclear. It might be as simple as letter case.
- Your tablet does not have a mimetype for epub, and CC's map is incorrect. This is possible but unlikely. Calibre's mimetype for epub is
all lower case, which as far as I can tell is correct.
- Moon+ is advertizing a mimetype that does not conform exactly to the industry-standard mimetype. This is not a reasonable assertion, given that it works in other cases. However, all the "other cases" might be a different version of android, so we can't rule this case out.
I am leaning toward your tablet returning a mimetype in mixed case. The file manager app could be converting the mimetype to lowercase, making it work with moon+. We should probably do the same thing, although it being necessary would be astonishing.
I don't know anything about your tablet. What version of android does it run?
