On my Android device(Motorola Moto G), it says that it failed to connect to proxy. I have enable the USB Debugging and i have installed AndroidSDK & AndroidNDK on my PC. All seems working perfectly but it does not preview what i have on my desktop to my Android device. Please resolve this issue, i want to develop apps too 
Hi!
Fuse is communicating with preview through wifi, make sure that you phone and computer are on the same network and it should work
Let me know if this is still a problem for you
