Maybe error raise (not attached window?) If right, see below:
Just Check view is attached to window (in WindowManagerContainer.java#onArrangementChanged):

// TODO: ChatHeadLibs: Fix error here (not attached window)
        if (motionCaptureView != null && motionCaptureView.getWindowToken() != null)
        windowManager.updateViewLayout(motionCaptureView, layoutParams);

After resolved that, maybe raise error when minimized chathead. Plz edit code in MinimizedArrangement.java#getBundle()

if (hero != null && hero.getHorizontalSpring() != null && hero.getVerticalSpring() != null) {
relativeXPosition = hero.getHorizontalSpring().getCurrentValue() * 1.0 / maxWidth;
relativeYPosition = hero.getVerticalSpring().getCurrentValue() * 1.0 / maxHeight;
}

All worked.
