Can't seem to get facebook friend's photos?

Question

I am trying to get my Facebook Friend's photos via the Graph API. This was my attempt:

public void getFacebookData(final AccessToken accessToken){
    //newMeRequest = My own data
    //myFriendsRequest = my mutual friends who have the app downloaded
    //Basically make 2 requests to one's Facebook info and return the names, links, id, and picture of the individual

    AccessToken accesstoken = AccessToken.getCurrentAccessToken();

    JSONArray friends = new JSONArray();
    GraphRequestBatch batch = new GraphRequestBatch(
            GraphRequest.newMeRequest(
                    AccessToken.getCurrentAccessToken(),
                    new GraphRequest.GraphJSONObjectCallback() {
                        @Override
                        public void onCompleted(
                                JSONObject jsonObject,
                                GraphResponse response) {
                            // Application code for user                            
                        }
                    }),
            GraphRequest.newMyFriendsRequest(
                    AccessToken.getCurrentAccessToken(),
                    new GraphRequest.GraphJSONArrayCallback() {
                        @Override
                        public void onCompleted(JSONArray jsonArray,
                                                GraphResponse response) {
                            // Application code for users friends
                            // Insert into our local DB
                            Toast.makeText(login.this, "" + response.toString(), Toast.LENGTH_SHORT).show();
                            try {
                                for (int i = 0; i < jsonArray.length(); i++) {
                                    JSONObject row = jsonArray.getJSONObject(i);
                                    System.out.println("Got id");
                                    datasource.createFriend(row.getString("name"), row.getString("id"));
                                    new GraphRequest(
                                            AccessToken.getCurrentAccessToken(),
                                            "/" + row.getString("id") + "/picture",
                                            null,
                                            HttpMethod.GET,
                                            new GraphRequest.Callback() {
                                                public void onCompleted(GraphResponse response) {
                                                    System.out.println("Got photo");
                                                }
                                            }
                                    );
                                }
                            } catch (JSONException e) {
                                throw new RuntimeException(e);
                            }
                            System.out.println("FriendsDB: " + jsonArray);
                        }
                    }
            )
    );
    batch.addCallback(new GraphRequestBatch.Callback() {
        @Override
        public void onBatchCompleted(GraphRequestBatch graphRequests) {
            // Application code for when the batch finishes
            Log.d(TAG, graphRequests.toString());

        }
    });
    batch.executeAsync();

However, the issue is that I can never seem to have the "Got Photo" message to print. I am confused because I looked at the GraphRequest constructor and found that this method would work best for me. However, the method never completes and I'm really not sure why it would fail. Any help would be appreciated. thanks!

EDIT: I have made sure I have freinds that are authenticated on my app and have the following permissions:

loginButton.setReadPermissions(Arrays.asList("user_friends", "public_profile", "email"));

I think you are trying to get all the friends of the logged in user, well from Graph API v2 you won't get the list of friends by calling USER_ID/friends. Now this will return users friends who use the app or has authorized himself to the particular facebook app.

Detail information about this can be found here

And regarding about photos of the user read the docs here.

Edit 1

For the profile picture fetch the user id from the graph API and

Add ProfilePictureView in your xml file

    <com.facebook.widget.ProfilePictureView
   android:id="@+id/friendProfilePicture"
   android:layout_width="wrap_content"
   android:layout_height="wrap_content"
   android:gravity="center_horizontal"
   android:padding="5sp"
   facebook:preset_size="small" />

Now from Java add the id of the user like this:-

ProfilePictureView profilePictureView;
profilePictureView = (ProfilePictureView) findViewById(R.id.friendProfilePicture);
profilePictureView.setProfileId(userId);

Or

Use Picasso to fetch image and add it to an ImageView using this link
