Android - get facebook profile picture

Question

I don\'t know why, but I am always getting null when I try to get the profile picture of the user. Do I need to set some specific permissions to get access?

Below is

Answer 1

I always received a response stating a FACEBOOK_NON_JSON_RESULT. So looking back in Facebook’s graph API explorer I noted a little checkbox with the label redirect checked. Some googling showed me that I needed to provide a parameter to my GraphRequest that disallows the redirect. Hence the correct request must be:

 Bundle params = new Bundle();
 params.putBoolean("redirect", false);

     new GraphRequest(
     AccessToken.getCurrentAccessToken(),
     "me/picture",
     params,
     HttpMethod.GET,
     new GraphRequest.Callback() {
        public void onCompleted(GraphResponse response) {
            try {
                String picUrlString = (String) response.getJSONObject().getJSONObject("data").get("url");   
                //Load picture url in imageView
                Glide.with(this).load(picUrlString).diskCacheStrategy(DiskCacheStrategy.SOURCE).into(profilePictureView);
            } catch (JSONException | IOException e) {
                e.printStackTrace();
            }
        }
    }
 ).executeAsync();
