        new Request(
                Session.getActiveSession(),
                "/"+f.getAlbumId()+"/picture",
                params,
                HttpMethod.GET,
                new Request.Callback() {
                    public void onCompleted(Response response) {
        /* handle the result */
                        Log.i("SocialManager", "" + response);
                        JSONObject obj = response.getGraphObject().getInnerJSONObject();

                        try {

                          JSONObject o = obj.getJSONObject("albums").getJSONObject("data");
                            String url = o.getString("url");
                           f.setImageUrl(url);
                        } catch (JSONException e) {
                            e.printStackTrace();
                        }
                    }
                }
        ).executeAsync();

FbAlbumItem : String albumId; String albumName; String albumCover; String imageUrl; String albumId; String albumName; String albumCover; String imageUrl;

Answer 1

Solved. I use my method with some change. Add this parameter

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

Thanks for inspiration.

Answer 2

Prerequisite - user_photos permission for non public albums

Get it with the cover_photo field

me/albums/album_id?fields=cover_photo

Doc reference here

Answer 3

U could have done like this.

final Session session = Session.getActiveSession();
    if (session.isOpened()) {
        final String authToken = session.getAccessToken();
        // saveToPreferences(ApplicationData.FB_TOKEN, authToken);
        Bundle params = new Bundle();
        params.putBoolean("redirect", false);
        params.putString("height", "400");
        params.putString("type", "normal");
        params.putString("width", "400");
        /* make the API call */
        new Request(
                session,
                "/me/albums/{album-id}",
                params,
                HttpMethod.GET,
                new Request.Callback() {
                    public void onCompleted(Response response) {
                        //cover_photo_fetch = response.cover_photo.toString();
                        Log.d("Picture", response.toString());
                        try {
                            userModel = UserModel.getInstance(mContext);
                            personPhotoUrl = response.getGraphObject().getInnerJSONObject().getJSONObject("data").getString("url");

                        } catch (JSONException e) {
                            e.printStackTrace();
                        }
                    }
                }
        ).executeAsync();
