Release builds gives files like this:
C:\Users\Superman\Documents\Flare\app-build\src\SpeedDate.no\Flare\.build\Android-Release\bin\Flare-debug.apk
Expected:
A filename without debug in the name.
The APK is automatically signed using a debug key from google unless you provide your own. So, you most likely got a debug APK containing a release binary there.
A little bit confusing, but not a bug. 
Superb, thanks!
