Hi,
I've been investigating the issue trying to get access to video files packaged in an AIR app from an ANE but they are sometimes compressed in the APK rather than just being stored. Once they are compressed you get the following error:
java.io.FileNotFoundException: This file can not be opened as a file descriptor; it is probably compressed
I think this has to be an error in the AIR packaging, as they shouldn't be compressed. Any files like mp3, mp4, png etc shouldn't be compressed according to the Android packager.
