Nit: |Profile| is only referenced in overridden method declarations. By
convention, there is no need to forward-declare it.

 
 namespace chromeos {
 
 // Class responsible for launching the demo app under a kiosk session.
 class DemoAppLauncher : public KioskProfileLoader::Delegate {
  public:
   DemoAppLauncher();
   virtual ~DemoAppLauncher();
 
   void StartDemoAppLaunch();
 
   static bool IsDemoAppSession(const std::string& user_id);
 
  private:
   // KioskProfileLoader::Delegate overrides:
   virtual void OnProfileLoaded(Profile* profile) OVERRIDE;
   virtual void OnProfileLoadFailed(KioskAppLaunchError::Error error) OVERRIDE;
 
-  Profile* profile_;
   scoped_ptr<KioskProfileLoader> kiosk_profile_loader_;
 
   DISALLOW_COPY_AND_ASSIGN(DemoAppLauncher);
 };
