fb.appid = '**************';
fb.permissions = ['publish_stream'];
fb.forceDialogAuth = true;
 fb.authorize();
fb.addEventListener('login', function(e){
    Ti.API.info("i'm here");
 if (e.success) {
        fb.requestWithGraphPath('me', {}, 'GET', function(e) {
    if (e.success) {
        alert(e.result);
    } else if (e.error) {
        alert(e.error);
    } else {
        alert('Unknown response');
    }
});
    }
    else if (e.cancelled) {
        // user cancelled
        alert('cancelled');
    }
    else {
        alert(e.error);
    }
});
fb.addEventListener('logout', function(e) {
    alert('Logged out');
});
