Fix crash on access clipboard on Android

A case where the accessing the clipboard is done when the application
does not have the input focus. Android does not allow access in this
case and returns null on the getPrimaryClip. This happens on some
examples like Analog Clock. Does not happen on autotests.
Fix was adding a test for null.
