Audio DroID3Tagger new app

i'm using this app with my nexus 5 but every time i use at the end of the process the app FC.
there is some developer that is able to decompile and adjust this app?
this app is no maintining since 2011 and the developer is not responding to mail.
i continue to use this app because is the only one that read the fingerprint of the song directly from storage.
sorry for my english.
