public booleanisFullscreenBouncer()
Like {@link #needsFullscreenBouncer}, but uses the currently visible security method, which makes this method much faster.

WARNING: This method might cause Binder calls.

public booleanisShowing()

        return mShowingSoon || (mRoot != null && mRoot.getVisibility() == View.VISIBLE);
public booleanneedsFullscreenBouncer()

return
True if and only if the security method should be shown before showing the notifications on Keyguard, like SIM PIN/PUK.

            SecurityMode mode = mKeyguardView.getSecurityMode();
