Posting user_generated photo from new native Share Dialog in FacebookSDK on android

问题

I'm, trying to post an image to the Facebook (with OpenGraph) using new SDK v3.5 Share Dialog described here

As a result I'm getting com.facebook.FacebookException: Error retrieving image attachment.

The image is added to the dialog like described in the documentation:

List<Bitmap> bitmaps = new ArrayList<Bitmap>();
bitmaps.add(bitmap);

FacebookDialog shareDialog = new FacebookDialog.OpenGraphActionDialogBuilder(ShareAwardActivity.this, action, "my_app:my_action", "my_object")
  .setImageAttachmentsForObject("my_object", bitmaps, true)
  .build();
facebookHelper.trackPendingDialogCall(shareDialog.present());

It looks like SDK stores image in the cache folder to be read by Facebook app, but Facebook app can't read or upload it somehow.

I tried setImageAttachmentsForAction - didn't help.

Also tried to add the image url to my_object - it doesn't respect the user_generated flag

Does anyone succeeded in doing this?
