I intergrated facebok posting into LocationReceiver.java and have successfully posted my location to my wall as travel post. i am having issues with receiver crashing when trying to post to facebook, if facebook isnt authorized yet. im thinking of using a shared_prefs to save whether or not if facebook has been authorized
