Why isn't my code copying files to another directory?

Why are my codes not working its way copy a file from a directory to another after being initialized? Where it does not seems to even loop into the copyFile class method? Is it because i have not given it开发者_开发百科 time to copy/transfer the file or have i done something wrong in my codes?

I'm rather new in android/programming can someone help?

Alertdialog onClick function to call upon the copyFile method.

It looks like you are trying to write to the archive directory itself, instead of to a new file inside that directory.
