import { game, Game } from 'cc';

export class AppLifecycle {
  static onLoad() {
    game.on(Game.EVENT_HIDE, this.onHide, this);
    game.on(Game.EVENT_SHOW, this.onShow, this);
  }

  static onHide() { console.log('Application entered the background'); }
  static onShow() { console.log('Application returned to the foreground'); }

  static onDestroy() {
    game.off(Game.EVENT_HIDE, this.onHide, this);
    game.off(Game.EVENT_SHOW, this.onShow, this);
  }
}

Call onLoad during startup and onDestroy when the listener owner is released.
