It looks like your problem is that you defined the name of your ServiceConnection variable in Italian. While there is certainly nothing inherently wrong with that practice in real world terms, the challenge is very specifically looking for a ServiceConnection named serviceConnection
.
In a similar vein, your Boolean is named mBound but the challenge is expecting to see isBound
.
Hope that helps!
