For example if there 1613d3de42cae84fadfa1befd082a2cf1bf72f9ad82aJohn Reck * is an {@link AnimatorUpdateListener} the animation will run on the UI thread, 1614d3de42cae84fadfa1befd082a2cf1bf72f9ad82aJohn Reck * regardless of the value of this hint.</p> 1615d3de42cae84fadfa1befd082a2cf1bf72f9ad82aJohn Reck * 1616d3de42cae84fadfa1befd082a2cf1bf72f9ad82aJohn Reck * <p>Regardless of whether or not the animation runs asynchronously, all 1617d3de42cae84fadfa1befd082a2cf1bf72f9ad82aJohn Reck * listener callbacks will be called on the UI thread.</p> 1618d3de42cae84fadfa1befd082a2cf1bf72f9ad82aJohn Reck * 1619d3de42cae84fadfa1befd082a2cf1bf72f9ad82aJohn Reck * <p>To be able to use this hint the following must be true:</p> 1620d3de42cae84fadfa1befd082a2cf1bf72f9ad82aJohn Reck * <ol> 1621d3de42cae84fadfa1befd082a2cf1bf72f9ad82aJohn Reck * <li>{@link #getAnimatedFraction()} is not needed (it will return undefined values).</li> 1622d3de42cae84fadfa1befd082a2cf1bf72f9ad82aJohn Reck * <li>The animator is immutable while {@link #isStarted()} is true.

It is guaranteed that all state changes that are 1632d3de42cae84fadfa1befd082a2cf1bf72f9ad82aJohn Reck * performed on the UI thread in the same frame will be applied as a single 1633d3de42cae84fadfa1befd082a2cf1bf72f9ad82aJohn Reck * atomic update, however that frame may be the current frame, 1634d3de42cae84fadfa1befd082a2cf1bf72f9ad82aJohn Reck * the next frame, or some future frame. This will also impact the observed 1635d3de42cae84fadfa1befd082a2cf1bf72f9ad82aJohn Reck * state of the Animator. For example, {@link #isStarted()} may still return true 1636d3de42cae84fadfa1befd082a2cf1bf72f9ad82aJohn Reck * after a call to {@link #end()}.
