Ok I only have 1 Apple device and that's my iPod touch and I just installed find my iPhone app on it. Ok so if my ipod got stollen do I have to have another apple device to track it or I can use any other device because I do got a android tablet

As far as I'm aware you need another Apple device to locate it. I. E an iPhone or iPad.
Sorry, but I hope you find your iPod soon.
