You have added many unrelated changes (e.g. code style) and have not explained well what you did and how and why you did it. Please remove the unrelated changes and add a better PR description.

Thank you, now I can see what's happening. I think it's better to use string constants instead of duplicating the strings (I'm referring to "doubleTap", "next", "show", which should be converted to DOUBLE_TAP, NEXT, SHOW).
