there 2 issues code.

the first you're using deprecated version of facebook sdk. if you're using 3.0.x of sdk, please not use facebook class, , use session , request classes instead. see https://developers.facebook.com/android/ tutorials , samples. doesn't affect correctness, brings me ...

your issue you're doing network request on main thread (exactly exception says). need wrap facebook.request call inside asynctask's doinbackground method.
