Looks your destination path lacks root slash as it should be /mnt/sdcard/destinationFolder not mnt/sdcard/destinationFolder as quoted error message indicates

This error could be vendor dependant, obviously the error is lack of permissions when trying to copy the files in /data/app/, most of the devices won't let you do that unless the device is rooted and you are using sudo commands, if you are trying to attack a global market with your application I'm sure you will have a lot of problems with that, and you should find a better approach.

Hope this Helps

Regards!
