Does such a thing exist?
I'm using a Xiaomi Mi4 Android mobile phone, it is running MIUI on Android 4.4.4 which means all the latest epub reading apps should work on it.
The EPUB has been validated through ePubCheck3.0.1 and benchmarked to an Adobe InDesign CC exported FXL EPUB to make sure it is according to standard as well.
On Readium is shows exactly as intended, two page spread (single html file for each image) with Audio playing in the background.
Is there an Android app capable of displaying such a book nicely? The closest I found was Moon+ Reader, however, they apparently have a bug with Audio controls, they will display the Audio controls inline so you see an image on one side and the audio controls on the other (view attached file).
