Thanks for your answer,
after fixing the problem you told me now the app is not stopping. What 
happens is that it is still unable to play the file and the logcat shows 
the next messages:

So it seems there is a problem with the aac decoder. I already posted a 
bug of the aac decoder of android 
(, but I do not know 
if this time is also directly related to the same issue.

Thanks for your replies,
