*** ** * ** *** Snackbars provide lightweight feedback about an operation. They show a brief message at the bottom of the screen on mobile and lower left on larger devices. Snackbars appear above all other elements on screen and only one can be displayed at a time. They automatically disappear after a timeout or after user interaction elsewhere on the screen, particularly after interactions that summon a new surface or activity. Snackbars can be swiped off screen. Snackbars can contain an action which is set via[setAction(CharSequence, android.view.View.OnClickListener)](https://developer.android.com/reference/android/support/design/widget/Snackbar#setAction(java.lang.CharSequence, android.view.View.OnClickListener)). To be notified when a snackbar has been shown or dismissed, you can provide a[Snackbar.Callback](https://developer.android.com/reference/android/support/design/widget/Snackbar.Callback)via[addCallback(BaseCallback)](https://developer.android.com/reference/android/support/design/widget/BaseTransientBottomBar#addCallback(android.support.design.widget.BaseTransientBottomBar.BaseCallback)).
