What does "by USB host cable" mean? If you mean that you connected a USB cable between the Nano and the phone, then that is not going to work.

The USB devices you can connect to your phone must be USB Masters (also known as USB Hosts). The Nano and other Arduinos are USB Slaves.

Thanks for your help !!

I finally success to connect a OTG(On The Go) cable between Nano and Android phone.

And I follow the step in this website(http://makezine.com/projects/android-arduino-led-strip-lights/) to build my Android application.
