Using Graph API , how to retrieve Images of the comments and replies to the comment?

Question

I am creating an Android App.The App have a feature that retrieve Facebook posts using Graph API.

My Problem
My Problem is , the received JSON lacks the following fields:

• Url for the images attached with the comments
  
• Replies to the comments
• Only No. of likes available. No Reactions list
• For posts containing more than one images , full_picture fields contains link to only one image. Where is the link for other images ?

I used the /me/posts to get the posts.

Why I can't get the above details ?

Steps taken
I searched Stackoverflow but The answers only mentioned how to get images and replies for individual commment(by using comment id) , but no reference how to get it alongs with the JSON received from "/me/posts" . (So , this is not a duplicate!!!!)

My Queries

• Why I can't get the above details ?
• What is the way to get comment's Images , replies,url for all images of the Parent post and Posts reactions in bundle.(that is along with the JSON of "/me/posts" without running /comment request for each and every comment?

My Code

Code the executes Graph Query

login_button.setReadPermissions(Arrays.asList(
                "public_profile", "email", "user_birthday", "user_friends","user_posts", "user_status")); // Setting permissions

 Bundle params = new Bundle();
               params.putString("fields", "message,created_time,id,full_picture,status_type,source,comments.summary(true),likes.summary(true)");

                params.putString("limit", "100");

  new GraphRequest( loginResult.getAccessToken(), "/me/posts", params, HttpMethod.GET,
                        new GraphRequest.Callback() {
                            public void onCompleted(GraphResponse response)  {
                            /* handle the result */
                            try {
                                EditText postsText = (EditText) findViewById(R.id.postText);
                                String res = response.toString();
                                res = res.replaceAll("\\{Response:\\s*\\w*\\W*\\s*[0-9]*\\W*\\w*:", "");
                                res = res.replaceAll("\\,\\s*error:\\s*null\\W*\\s*","");
                                postsText.setText(res);
                                writeToFile(res,"response");
                            }
                            catch (Exception e) {
                                    e.printStackTrace();
                                }
                                }
                            }

                ).executeAsync();


            }

            @Override
            public void onCancel() {
                txtstatus.setText("Login canceled");
            }

            @Override
            public void onError(FacebookException error) {
                txtstatus.setText("Login failed"+error.getMessage());
            }
        });

Answer 1

Well, regarding "reaction list", this is available only for the Page owner (starting from 2018 Febraury).

Read the Graph API docs: https://developers.facebook.com/docs/graph-api/reference/v2.12/post

"For Posts on a Page:

Any valid access token can read posts on a public Page, but responses will not include User information. A Page access token can read all Posts posted to or posted by that Page, and responses will include User information."
