I installed Kindle for android in my phone.
I have ebook in mobi format and mp3.
The mp3 is audiobook for the ebook.
I have put the mobil and mp3 in Kindle folder.
The ebook can read but how do I play the mp3 together and sync with text?
If you would like to have the audio match the text then you would have to create a read aloud ebook using EPUB 3. You can learn more about this at this link
