Hello guyz… so I was able to log-in to facebook now . .when i tried the ‘post a photo’ from the ‘facebook’ sample, it didnt work. . so im left clueless why it didnt, .it’s a sample, it should work… .instead i get this error : “the page you requested cannot be displayed right now. it may be temporarily unavailable, the link you clicked may be broken or expired, or you may not have permission to view this page.”
can you teach me how to post a photo from my phone at my facebook wall??
thnx :DD
Can you post your code please? it’s hard to know where you may have gone wrong without seeing it.

– Project: Facebook Connect sample app
–
– Date: December 24, 2010
–
– Version: 1.5
–
– File name: main.lua
–
– Author: Corona Labs
–
– Abstract: Presents the Facebook Connect login dialog, and then posts to the user’s stream
– (Also demonstrates the use of external libraries.)
–
– Demonstrates: webPopup, network, Facebook library
–
– File dependencies: facebook.lua
–
– Target devices: Simulator and Device
–
– Limitations: Requires internet access; no error checking if connection fails
–
– Update History:
– v1.1 Layout adapted for Android/iPad/iPhone4
– v1.2 Modified for new Facebook Connect API (from build #243)
– v1.3 Added buttons to: Post Message, Post Photo, Show Dialog, Logout
– v1.4 Added …{“publish_stream”} … permissions setting to facebook.login() calls.
– v1.5 Added single sign-on support in build.settings (must replace XXXXXXXXX with valid facebook appId)
–
– Comments:
– Requires API key and application secret key from Facebook. To begin, log into your Facebook
– account and add the “Developer” application, from which you can create additional apps.
–
– IMPORTANT: Please ensure your app is compatible with Facebook Single Sign-On or your
– Facebook implementation will fail! See the following blog post for more details:
