// Exclusive Access Manager Android class is the Exclusive Access Manager
// wrapper used for synchronization of Pointer Lock, Keyboard Lock and
// Fullscreen features. The main responsibilities of EAM are to monitor which
// features are currently in use and when the features exit criteria are met
// (e.g. ESC key is pressed). This is done by a set of custom controllers for
// each feature.
// ExclusiveAccessManagerAndroid uses the ExclusiveAccessContextAndroid which
// as the delegate.
