My android phone and my IIS are both connected to the same network. I wonder are there any ways that let me wirelessly debug javascript app which is running on android's chrome ?
Have you tried using Weinre? http://people.apache.org/~pmuellr/weinre/docs/latest/
There is also the option to use PhoneGap's working version of it for quickly trying out: http://debug.phonegap.com/
