This is my package name: com.abc.ss
Now i have manually created a folder with package name com.abc.s in mnt/sdcard/Android/obb/com.abc.ss/main.2.com.abc.ss.obb
But when i run the sample app it says Downloading failed:
Here is my screen shot:
Here my code;

what is wrong with this?
EDIT:
XAPKFile[] xAPK is the place where we have given like its a main,filesize and version code
expansionFilesDelivered() is the method where it checks for the filename
