Description Tyson 2014-04-29 14:04:04 UTC
PROBLEM: After you take the picture, the application crashes due to a NullPointerException.

In MainActivity.cs:

Line 32:  Uri contentUri = Uri.FromFile(_file);

_file is NULL.

A fixed version of the Recipe..

I moved the fields (_file, _dir) into a static class (App) and created a static bitmap there as well.

The bitmap needs to be static in order to survive the OnCreate() method, which is  firing AFTER the OnActivityResult() method..

The fact that those events fire in that order seems like a whole other bug in my opinion...
Comment 2 Tyson 2014-04-29 15:00:17 UTC
Actually, the event order was due to me turning the device sideways to take a landscape shot, after starting the application in portait.. disregard that bit..
Comment 4 Amy Burns 2014-06-04 07:12:56 UTC
Added fix and tested. this should be working now with Tyson's fix.
