can we detect location if GPS is not accesible

[shawn peter]

I need to know whether there is a way to detect location if GPS is not accesible?

I think you can get the IP address and there are APIs which can resolve location from IP.

how to get IP address for Mobile phone ?

That would be a dynamic IP of the telco provider network - not much you can infer from that.

But you can use the network location provider if the user has enabled that. That's what the ACCESS_COARSE_LOCATION permission is all about (as opposed to the ACCESS_FINE_LOCATION which covers GPS). As usual, the Android docs have all the details: http://developer.android.com/guide/topics/location/obtaining-user-location.html

You really need to spend time reading through the documentation, most of your question are answered right there, even with code examples.
