Android app created, where is the .apk?

  Once you have created the android app, which files do you move to the android device so you can test it? I do not see any .apk file that I would normally associate with an andriod app install file. Does Robohelp create the install file or do I have to create the install file? If I have to create it how is that done? Any instructional reference would be appreciated.

Thanks for any assistance,

Anthony
