Facebook Android SDK 4.5.0 get email address

Question

I\'m currently creating a test application to test using the latest facebook SDK to update our existing application problem is that I need to get the email address which I k

Answer 1

Putting this code:

btnLoginFb.setReadPermissions(Arrays.asList("email"));

before

RegisterCallback

should solve the problem.

Answer 2

You need to ask for parameters to facebook in order to get your data. Here I post my function where I get the facebook data. The key is in this line:

parameters.putString("fields", "id, first_name, last_name, email,gender, birthday, location"); // Parámetros que pedimos a facebook

Hope it helps you.

btnLoginFb.registerCallback(callbackManager, new FacebookCallback<LoginResult>() {

        @Override
        public void onSuccess(LoginResult loginResult) {

            System.out.println("onSuccess");
            progressDialog = new ProgressDialog(LoginActivity.this);
            progressDialog.setMessage("Procesando datos...");
            progressDialog.show();
            String accessToken = loginResult.getAccessToken().getToken();
            Log.i("accessToken", accessToken);

            GraphRequest request = GraphRequest.newMeRequest(loginResult.getAccessToken(), new GraphRequest.GraphJSONObjectCallback() {

                @Override
                public void onCompleted(JSONObject object, GraphResponse response) {
                    Log.i("LoginActivity", response.toString());
                    // Get facebook data from login
                    Bundle bFacebookData = getFacebookData(object); 
                }
            });
            Bundle parameters = new Bundle();
            parameters.putString("fields", "id, first_name, last_name, email,gender, birthday, location"); // Parámetros que pedimos a facebook
            request.setParameters(parameters);
            request.executeAsync();
        }

        @Override
        public void onCancel() {
            System.out.println("onCancel");
        }

        @Override
        public void onError(FacebookException exception) {
            System.out.println("onError");
            Log.v("LoginActivity", exception.getCause().toString());
        }
    });



private Bundle getFacebookData(JSONObject object) {

        try {
            Bundle bundle = new Bundle();
            String id = object.getString("id");

            try {
                URL profile_pic = new URL("https://graph.facebook.com/" + id + "/picture?width=200&height=150");
                Log.i("profile_pic", profile_pic + "");
                bundle.putString("profile_pic", profile_pic.toString());

            } catch (MalformedURLException e) {
                e.printStackTrace();
                return null;
            }

            bundle.putString("idFacebook", id);
            if (object.has("first_name"))
                bundle.putString("first_name", object.getString("first_name"));
            if (object.has("last_name"))
                bundle.putString("last_name", object.getString("last_name"));
            if (object.has("email"))
                bundle.putString("email", object.getString("email"));
            if (object.has("gender"))
                bundle.putString("gender", object.getString("gender"));
            if (object.has("birthday"))
                bundle.putString("birthday", object.getString("birthday"));
            if (object.has("location"))
                bundle.putString("location", object.getJSONObject("location").getString("name"));

            return bundle;
        }
      catch(JSONException e) {
        Log.d(TAG,"Error parsing JSON");
      }
    return null;
}

Answer 3

Instead of getting the value of the graphResponse, access the email using the JSONObject me

userEmail = jsonObject.getString("email");

Answer 5

I guess getting email permissions can help..

LoginManager.getInstance().logInWithReadPermissions(
fragmentOrActivity,
Arrays.asList("email"));

Answer 6

You can also use GraphResponse object to get the values

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());
                            try {
                                // Application code
                                String email = response.getJSONObject().getString("email");
                                txtStatus.setText("Login Success \n" + email);
                            }catch(Exception e){
                                e.printStackTrace();;
                            }
                        }
                    });
            Bundle parameters = new Bundle();
            parameters.putString("fields", "id,name,email,gender,birthday");
            request.setParameters(parameters);
            request.executeAsync();
        }

        @Override
        public void onCancel()
        {
            txtStatus.setText("==============Login Cancelled=============");
        }

        @Override
        public void onError(FacebookException exception)
        {
            txtStatus.setText("==============Login Error=================");
            exception.printStackTrace();
        }
    });
