APK with MP3 bigger than with WAV?

My game without music compiled to *.APK was about 6MB.
I added 4 WAV files (about 6MB total) as audio.loadStream, and my APK was 12.4MB
So I compresed WAV to MP3 and changed these files (about 0.5MB total) in my game. And now my APK with MP3 is 12.8MB!

How is it possible? [import]uid: 193524 topic_id: 34313 reply_id: 334313[/import]

Silly question, but you didn’t by any chance leave the WAV files in there did you?

Thank you! I made a few new tests and I know the reason:
I removed WAV files from audio.loadStream() in my main.lua file but I left these files in my project’s subdirectory.

Looks that Corona puts all files from project’s directory and subdirectories into APK regardless of my code! Is it true?

Now my APK is 5.2MB. [import]uid: 193524 topic_id: 34313 reply_id: 136437[/import]
