Public methods

addGlobalWindowViewsListener

Added in version 36.1

public static void addGlobalWindowViewsListener (Executor executor, 
                Consumer<List<View>> consumer)

Adds a listener that is notified whenever the value of getGlobalWindowViews() changes. The current value is provided immediately using the provided Executor. The value is initially relayed using the main thread and then posted to the Executor. Using a direct Executor and doing heavy calculations can cause performance issues. If this Consumer is already registered, then this method is a no op.

Parameters
`executor`	`Executor`: This value cannot be `null`.
`consumer`	`Consumer`: This value cannot be `null`.
