I have got FB auth to work properly in the settings, also i was able to post to facebook with out user interaction.

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
