Hi im using Facebook Android Share Dialog but After successfully sharing a page on a facebook I get a post id like this: UzpfSTEwMDAwNzU5NjMxNDE5MDoxNjQ0MzI4NjU1ODMwMzI5

I check it via graph api but it still error?

   "error": {
   "message": "(#100) This api call does not support permalink tokens",
   "type": "OAuthException",
   "code": 100,
   "fbtrace_id": "B5OJZBt5DRL"
   }
 }

The post id UzpfSTEwMDAwNzU5NjMxNDE5MDoxNjQ0MzI4NjU1ODMwMzI5 is encoded to Base64 you should decode it.

Tried to decode it using https://www.base64decode.org/ and I got this S:_I100007596314190:1644328655830329. You could do a string manipulation and parse the postId to 100007596314190_1644328655830329. And you could use it on the Graph API to get the post.

This link should help you http://developer.android.com/reference/android/util/Base64.html in decoding Base64 in Android.
