How to use FB.Feed (not FB.API) in sharing a screenshot in picture parameter?

I’m using the Facebook SDK package for Unity in building an android game. I want to take a screenshot (Application.CaptureScreenshot(…)) then pass its url to the “picture” parameter in FB.Feed method .

The problem is that I can’t get the url of the screenshot (that supposed to be saved at Application.persistentDataPath). I’ve tried somthing like:


but it didn’t work! it gave me that error: “picture URL is not properly formated” .

and I don’t want to use “FB.API”. Any Idea?

Thanks in advance!

I made it :slight_smile: btw I am a newbie about Unity and C# also. So i am not sure this is best way or not

Anyway FB.API use wwwForm so I made own input form with wwwForm like below and use FB.API

private IEnumerator TakeScreenshot()
	yield return new WaitForEndOfFrame();
	var width = Screen.width;
	var height = Screen.height;
	var tex = new Texture2D(width, height, TextureFormat.RGB24, false);
	// Read screen contents into the texture
	tex.ReadPixels(new Rect(0, 0, width, height), 0, 0);
	byte[] screenshot = tex.EncodeToPNG();

           //screenShottexture is Texture to another Image of own GUI
	screenShot.texture = tex;

	var wwwForm = new WWWForm();
	wwwForm.AddBinaryData("image", screenshot, "intotheblack.png");

            // screenWWWForm is private variable to own GUI
	screenWWWForm = wwwForm;

           // this is my own GUI panel. (I am using 4.6 new GUI

// I didn’t call FB.API on this Fuction. I call it from my own GUI;

// FB.API(“me/photos”, Facebook.HttpMethod.POST, Callback, wwwForm);

Anyway my idea is draw tex on another GUI RawImage, so user can check image and type other input form. and upload;
