That broadcast tells you when the current input method component has changed
(that is the user has switched from one input method to another).
Interaction with the current input method is done through the view APIs.
For the case of the IME being shown, you find out about this indirectly
through your view hierarchy being resized to accommodate it. There is no
direct "IME is shown" state.
