Integrate Facebook SDK in android and retrieve user's email

Question

I want to retrieve logged in user email. This is what I tied, but not retrieving the email. I could retrieve only id, first name, last name but not the email

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

            GraphRequest request = GraphRequest.newMeRequest(
                    loginResult.getAccessToken(),
                    new GraphRequest.GraphJSONObjectCallback() {
                        @Override
                        public void onCompleted(JSONObject object, GraphResponse response) {
                            Log.v("LoginActivity", response.toString());

                            // Application code
                            try {
                                String userEmail = object.getString("email");
                                String userId = object.getString("id");
                                emailEditText.setText(userEmail);
                                new SignupTask(SignupActivity.this, userId, userEmail).execute();

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

                        }
                    });

            Bundle parameters = new Bundle();
            parameters.putString("fields", "id, first_name, last_name, email"); // Parámetros que pedimos a facebook
            request.setParameters(parameters);
            request.executeAsync();
        }

        @Override
        public void onCancel() {

        }

        @Override
        public void onError(FacebookException e) {

        }
    });

    LoginManager.getInstance().logInWithReadPermissions(this, Arrays.asList("public_profile", "email", "user_friends"));

What do I have missed....

Is it happening for all user or few?? Because most of the FB users are logged in via phone number but not email. So you will get null value for such users — Mohammed Atif, Aug 09 '16 at 07:56

ohk..try this code its working for me...    

LoginButton loginButton = (LoginButton) findViewById(R.id.login_button);
        loginButton.setBackgroundResource(R.drawable.fb);
        loginButton.setCompoundDrawablesWithIntrinsicBounds(null, null, null, null);
        loginButton.setReadPermissions(Collections.singletonList("public_profile, email, user_birthday, user_friends"));

        callbackManager = CallbackManager.Factory.create();
        if (netWorkStatus) {
            LoginManager.getInstance().registerCallback(callbackManager, new FacebookCallback<LoginResult>() {
                @Override
                public void onSuccess(LoginResult loginResult) {
                    // App code
                    //Store Facebook data to webservice .
                    GraphRequest request = GraphRequest.newMeRequest(
                            loginResult.getAccessToken(),
                            new GraphRequest.GraphJSONObjectCallback() {
                                @Override
                                public void onCompleted(JSONObject object, GraphResponse response) {
                                    // Application code
                                    try {
                                        // String picture = object.getString("picture");
                                        //JSONObject jobj = new JSONObject(picture);
                                        //JSONObject dataObj = jobj.getJSONObject("data");

                                        name = object.getString("name");
                                        userEmail = object.getString("email");
                                        //String url = dataObj.getString("url").replace("\\", "");

                                    } catch (Exception e) {
                                        e.printStackTrace();
                                    }

                                }
                            });

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

                }

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

                }

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

                }

            });
        }

I tried it. But same issue was there. The reason for happen this was. I have used ReadPermission and PublishPermission at once — senps, Aug 12 '16 at 05:25

CallbackManager callbackManager ;

//in OnCreate  initialize it
callbackManager = CallbackManager.Factory.create();


//after that overide onActivityResult
@Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);

callbackManager.onActivityResult(requestCode, resultCode, data);
        }
