android failed to load m4a

[Novice]

I ported to apk but
failed to load the m4a file
when I ran it.

So I tried porting ogg, m4a, and rpgmvo all together and I did not fail again. I already checked whether it was upper case or not. I do not know what I did wrong.

I want you to understand that I'm not good at English.

Please give the full name of the audio file and answer the following questions:
1) is the game encrypted or not?
2) what Version number is listed in the title line of the rpg_core.js file?
3) are both ogg and m4a versions available in the project?
4) what codec have you used for the m4a-file?
