The problem is that it's not copying the image at the selected path.

Here is the error:

20:19:00.671 1437 ERROR ReceiptWallet Cannot load image

Ignore my last post - I figured out the problem.

I wasn't initializing mIv (the ImageView) properly! Such a stupid error, and I spent countless hours on this thinking it was something to do with the Intent call.
