Hi!

I am using your HeadScrollView inside a custom Card of CardScrollView. It's work fine but when i do swipe back to return to the main Timeline, onSensorChanged continues to work. I put a Log.d inside.

I also have problems when i have a CardScrollView. One card has HeadScrollView. When i swpie left to go to another card, It is called "deactivate" so Sensor stops. However if one card open another activity and i swipe back to return to the CardScrollView, onVisibilityChanged it's called with visibility = VISIBLE so sensor is register but HeadScrollView it is not VISIBLE.

Sorry for my bad english. If you don't understand me, Ask me and i'll try to explain better.

When I try to use the GlassVoice-xe22.jar library at the same time as guava I am getting the following error:
UNEXPECTED TOP-LEVEL EXCEPTION:
com.android.dex.DexException: Multiple dex files define Lcom/google/common/annotations/Beta;

I think this might be that GlassVoice is using guava as well and I'm using a different version? Any idea which version?

Android ListView has smoothScrollToPosition which has a much better scrolling effect, more like the "ok glass" menu.

To efficiently enable a detection similar to the one used in the main menu of glass, create a second implementation that caches a. hotwordVoiceConfig and b. phrasesVoiceConfig.

The current implementation targets mainly always on use cases

When using the library inside a CardScrollView, the parent is probably at some time (while swiping furiously) already recycled.

Changing
((View) getParent()).invalidate();
into
if(getParent() != null) ((View) getParent()).invalidate();

(HeadImageView.java last line of onSensorChanged(SensorEvent event))

Fixes this problem
