Android Facebook sdk 4.2 cannot receive email

I am using facebook sdk 4.2 for my android application. But I could not get my email address, and it does not show the value for email. However, I can get other value, such as name, link, identifier, gender. There are several topics about this from stackoverflow, but they use the old version of sdk, the class is different. Please help, here is my code.

FacebookSdk.sdkInitialize(this.getApplicationContext());
callbackManager = CallbackManager.Factory.create();

LoginManager.getInstance().registerCallback(callbackManager,
  new FacebookCallback < LoginResult > () {
   @Override
    public void onSuccess(LoginResult loginResult) {

      Toast.makeText(MainActivity.this, "SUCCESS", Toast.LENGTH_SHORT).show();

      GraphRequest request = GraphRequest.newMeRequest(
        loginResult.getAccessToken(),
        new GraphRequest.GraphJSONObjectCallback() {
        @Override
          public void onCompleted(
            JSONObject object,
            GraphResponse response) {
            // Application code 
            try {
              String id = object.getString("id");
              String name = object.getString("name");

              String email = object.getString("email"); //Get null value here

              String gender = object.getString("gender");

              Toast.makeText(MainActivity.this, "HI," + name + "Gender: " + gender, Toast.LENGTH_SHORT).show();

            } catch (JSONException e) {
              Toast.makeText(MainActivity.this, "Error", Toast.LENGTH_SHORT).show();
              e.printStackTrace(); 

            }
          }
        });
      Bundle parameters = new Bundle();
      parameters.putString("fields", "id,name,email,gender");
      request.setParameters(parameters);
      request.executeAsync();
    }

    @Override
    public void onCancel() {
      // App code
    }

    @Override
    public void onError(FacebookException exception) {
      // App code   
    }
  });

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