12-02 09:48:53.410 27155-27155/com.bignerdranch.android.photogallery E/RecyclerView: No adapter attached; skipping layout
please help…feels like i am stuck with something trivial but not able to find solution.
Make sure your device/emulator can access the internet. Try opening a web browser on the device and navigating to some web page.
I would also try a few different URLs to see if that makes a difference.
Me too.The web browser on the emulator can fetch any web page.There is no result even I run the project you proved.
Can you post your log statements?

I would put a breakpoint in FlickrFetcher and use the debugger to pull out the exact url you are trying to hit (or log it out). Is it a valid URL? Does it work on your computer?
@zannenkiki …if you are using a work PC , and access is an issue there…then even though you can access emulator browser…you cant get to to work via AS. (stackoverflow has answers to configuring emulator network / ssid and port settings)
even as you go ahead it will create an issue since you have to access a photo sharing website (social sites are usually blocked by employers) and yahoo login.
i tried it on open nework and i finished the chapter like a breeze.
