With new api and your custom button for facebook you can use below code:

put below gradle in your gradle file:

 compile 'com.facebook.android:facebook-android-sdk:4.20.0'

  Newer sdk does not need initializaion .

    private CallbackManager callbackManager;
    @Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    FacebookSdk.sdkInitialize(LoginActivity.this);//Is now depricated
    setContentView(R.layout.activity_login);
    callbackManager = CallbackManager.Factory.create();
    }

onActivityResult:

        @Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
        callbackManager.onActivityResult(requestCode, resultCode, data);
         }

Button Click:

   @Override
    public void onClick(View v) {
    switch (v.getId())
    {
        case R.id.btn_f_sign_in_login:
            LoginManager.getInstance().logInWithReadPermissions(
                    this,
                    Arrays.asList("user_friends", "email", "public_profile"));

            LoginManager.getInstance().registerCallback(callbackManager,
                    new FacebookCallback() {
                        @Override
                        public void onSuccess(LoginResult loginResult) {
                            setFacebookData(loginResult);
                        }

                        @Override
                        public void onCancel() {
                        }

                        @Override
                        public void onError(FacebookException exception) {
                        }
                    });
            break;
    }
}

setFacebookData:

     private void setFacebookData(final LoginResult loginResult)
       {
    GraphRequest request = GraphRequest.newMeRequest(
            loginResult.getAccessToken(),
            new GraphRequest.GraphJSONObjectCallback() {
                @Override
                public void onCompleted(JSONObject object, GraphResponse response) {
                    // Application code
                    try {
                        Log.i("Response",response.toString());

                        String email = response.getJSONObject().getString("email");
                        String firstName = response.getJSONObject().getString("first_name");
                        String lastName = response.getJSONObject().getString("last_name");
                        String gender = response.getJSONObject().getString("gender");



                        Profile profile = Profile.getCurrentProfile();
                        String id = profile.getId();
                        String link = profile.getLinkUri().toString();
                        Log.i("Link",link);
                        if (Profile.getCurrentProfile()!=null)
                        {
                            Log.i("Login", "ProfilePic" + Profile.getCurrentProfile().getProfilePictureUri(200, 200));
                        }

                       Log.i("Login" + "Email", email);
                        Log.i("Login"+ "FirstName", firstName);
                        Log.i("Login" + "LastName", lastName);
                        Log.i("Login" + "Gender", gender);


                    } catch (JSONException e) {
                        e.printStackTrace();
                    }
                }
            });
    Bundle parameters = new Bundle();
    parameters.putString("fields", "id,email,first_name,last_name,gender");
    request.setParameters(parameters);
    request.executeAsync();
}

get Facebook Friends Who has downoaded your app:

replace parameters.putString("fields", "id,email,first_name,last_name");

with parameters.putString("fields", "id,email,first_name,last_name,friends");

Add below logic to get friends Data

                if (object.has("friends")) {
                  JSONObject friend = object.getJSONObject("friends");
                  JSONArray data = friend.getJSONArray("data");
                  for (int i=0;i
