Finding your location when using Internet in android

I have implemented location identification using GPS in android in my application but now if G开发者_如何转开发PS is not available or disabed then how to identify location when internet is enabled in device. Whether using google API or triangulation or some thing else. Thank You.

Have you read over this official documentation yet?

Android will do it automatically.
