No Result From Barcode Scanner?

The resultCode is used to determine the intention, the "why" you have called the activity for result. Nothing more, nothing less... I would just remove the if (requestCode == 0) as it isn't really important.

The value of RESULT_OK is in fact -1 (http://developer.android.com/reference/android/app/Activity.html#RESULT_OK).

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
