Facebook SDK 3.22 (android) - me/friends return wrong user's friends id

Question

I want my app to get ids and names of user's friends that have used the app too and find the id I need by the name. Then I want to use feed dialog with parameter "TO" to post to friend's wall. I thought it would be easy. Just use me/friends. Here is request:

if(session.getState().isOpened()){
        Log.i(TAG, "Creating request");
        Request friendRequest =  new Request(session, "/me/friends", null, HttpMethod.GET, new Request.Callback() {
            public void onCompleted(Response response) {
                Log.w(TAG, "Complete!" + response.toString());

                JSONArray usersArrays = new JSONArray();

                try {
                    Log.i(TAG, "Converting to userObject");
                    usersArrays = response.getGraphObject().getInnerJSONObject().getJSONArray("data");

                    for (int i = 0; i < usersArrays.length(); i++){
                        Log.i(TAG, "Reading " + i + " user");
                        JSONObject user = usersArrays.getJSONObject(i);

                        Log.i(TAG, "Getting name and id");
                        String userId = user.getString("id");
                        String userName = user.getString("name");

                        Log.i(TAG, "Now checking: " + userName + " with id: " + userId);

                        if (userName.equals(name)){
                            Log.w(TAG, "He was found! Here is his id: " + userId);
                            postToWall(userId);

                        } else if (i == (usersArrays.length() - 1)){
                            Log.e(TAG, name + " does not use the app yet!");
                            //no ways
                        }
                    }

                } catch (JSONException e) {
                    Log.e(TAG, "Error: " + e);
                    Toast.makeText(context, "Error", Toast.LENGTH_LONG).show();

                }
            }
        }
        );

        Log.i(TAG, "Sending request");
        friendRequest.executeAndWait();

Here is my response:

{Response:  responseCode: 200, graphObject: GraphObject{graphObjectClass=GraphObject, state={"summary":{"total_count":46},"data":[{"id":"383791018465143","name":"Friend Name"}],"paging":{"next":"..."}}}, error: null, isFromCache:false}

Then I found this site and decided to find out friend's id. It was not the same.

When using feed dialog my app crashes with facebook error: incorrect user. What can I do about it?

Thanks in advance, Sergey
