Solution
There is a limitations on opening compressed files in the assets folder. This is because uncompressed files can be directly memory mapped into the processes virtual address space, therefore avoiding needing the same amount of memory again for decompression.
Dealing with Asset Compression in Android Apps discusses some techniques in dealing with compressed files. You can trick `aapt` into not compressing the file by using an extension that is not compressed (e.g. `mp3`) or you can manually add them to the `apk` without compression instead of getting `aapt` to do the work.
