Bugfix for devices with Android versions below 4.4
App could crash or header view could just be not selectable.
This bugfix only applies for Android devices with versions below 4.4 (KitKat).
Thanks, I'll have a look and merge it as soon as possible (which can take some time).
no problem. thank you anyway.
I have just reworked the bugfix. I tested it with Android 4.2.2 (API Level 17) and 5.1 (22).
