When QWindowSystemInterface::handleKeyEvent() is called under
QtAndroidInput's keyDown() JNI native method callback, it throws
the following warning:
W Gallery : QObject: Cannot create children for a parent that is in a
different thread.
W Gallery : (Parent is QGuiApplication(0x707968a2e0), parent's thread
is QThread(0x70d6477280), current thread is QThread(0x70d18ff790)
when no keyboard QInputDevice has been registered, this behavior is
present at least on Android Emulators.
