Android: assets folder access

/* How to use access files stored in the assets folder:
 *
 * Files saved in the assets/ directory are not given a resource ID, so you can't reference them through the R class or from XML resources. 
 * Instead, you can query files in the assets/ directory like a normal file system and read raw data using AssetManager.
 * 
 * However, if all you require is the ability to read raw data (such as a video or audio file), then save the file in the res/raw/ directory 
 * and read a stream of bytes using openRawResource().
 *
 * Notes:
 *      * AssetManager.list(String path)
 *          * path: 
 *              * To get a list of the items in the "assets" folder: Empty string ("")
 *              * Otherwise, the path to the item contain in "assets" (i.e. "midi", "midi/turbo.mid")
 *
