title: Not receiving "keyboardWillHide" event on Android with React Native
body: <p>I am trying to dock a view to the top of the keyboard on iOS and Android. I've currently got this working with <code>DeviceEventEmitter</code>, but I never receive the <code>keyboardWillHide</code> event on Android. Is this expected behavior or is this a bug in <code>DeviceEventEmitter</code>?</p>
