Android Facebook 4.0 SDK Come ottenere e-mail, data di nascita e sesso dell'utente

Sto usando il seguente codice. Voglio la data di nascita, l'e-mail e il genere dell'utente. Per favore aiuto. Come recuperare quei dati?

Questo è il mio onViewCreated()dentro il frammento.

@Override
public void onViewCreated(View view, Bundle savedInstanceState) {

    // Setup TextView.
    mTextDetails = (TextView) view.findViewById(R.id.text_details);

    // Set up Login Button.
    LoginButton mButtonLogin = (LoginButton) view.findViewById(R.id.login_button);
    // setFragment only if you are using it inside a Fragment.
    mButtonLogin.setFragment(this);
    mButtonLogin.setReadPermissions("user_friends");
    mButtonLogin.setReadPermissions("public_profile");
    mButtonLogin.setReadPermissions("email");
    mButtonLogin.setReadPermissions("user_birthday");

    // Register a callback method when Login Button is Clicked.
    mButtonLogin.registerCallback(mCallbackManager, mFacebookCallback);

}

Questo è il mio metodo di richiamata.

private FacebookCallback<LoginResult> mFacebookCallback = new FacebookCallback<LoginResult>() {
    @Override
    public void onSuccess(LoginResult loginResult) {
        Log.d("Shreks Fragment", "onSuccess");


        Profile profile = Profile.getCurrentProfile();
        Log.d("Shreks Fragment onSuccess", "" +profile);

        // Get User Name
        mTextDetails.setText(profile.getName() + "");

    }


    @Override
    public void onCancel() {
        Log.d("Shreks Fragmnt", "onCancel");
    }

    @Override
    public void onError(FacebookException e) {
        Log.d("Shreks Fragment", "onError " + e);
    }
};

Questo non è il modo giusto per impostare le autorizzazioni mentre le sovrascrivi con ogni chiamata di metodo.

Sostituisci questo:

mButtonLogin.setReadPermissions("user_friends");
mButtonLogin.setReadPermissions("public_profile");
mButtonLogin.setReadPermissions("email");
mButtonLogin.setReadPermissions("user_birthday");

Con quanto segue, poiché il metodo setReadPermissions()accetta un ArrayList:

loginButton.setReadPermissions(Arrays.asList(
        "public_profile", "email", "user_birthday", "user_friends"));

Anche qui è come eseguire una query su dati extra GraphRequest:

private LoginButton loginButton;
private CallbackManager callbackManager;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_login);

    loginButton = (LoginButton) findViewById(R.id.login_button);

    loginButton.setReadPermissions(Arrays.asList(
            "public_profile", "email", "user_birthday", "user_friends"));

    callbackManager = CallbackManager.Factory.create();

    // Callback registration
    loginButton.registerCallback(callbackManager, new FacebookCallback<LoginResult>() {
        @Override
        public void onSuccess(LoginResult loginResult) {
            // App code
            GraphRequest request = GraphRequest.newMeRequest(
                    loginResult.getAccessToken(),
                    new GraphRequest.GraphJSONObjectCallback() {
                        @Override
                        public void onCompleted(JSONObject object, GraphResponse response) {
                            Log.v("LoginActivity", response.toString());

                            // Application code
                            String email = object.getString("email");
                            String birthday = object.getString("birthday"); // 01/31/1980 format
                        }
                    });
            Bundle parameters = new Bundle();
            parameters.putString("fields", "id,name,email,gender,birthday");
            request.setParameters(parameters);
            request.executeAsync();


        }

        @Override
        public void onCancel() {
            // App code
            Log.v("LoginActivity", "cancel");
        }

        @Override
        public void onError(FacebookException exception) {
            // App code
            Log.v("LoginActivity", exception.getCause().toString());
        }
    });
}

MODIFICARE:

Un possibile problema è che Facebook presume che la tua email non sia valida. Per testarlo, usa Graph API Explorer e prova a ottenerlo. Se anche lì non riesci a ricevere la tua e-mail, modificala nelle impostazioni del tuo profilo e riprova. Questo approccio ha risolto questo problema per alcuni sviluppatori che commentavano la mia risposta.

Utilizza questo frammento per ottenere tutte le informazioni sul profilo

private FacebookCallback<LoginResult> callback = new FacebookCallback<LoginResult>() {
        @Override
        public void onSuccess(LoginResult loginResult) {
            AccessToken accessToken = loginResult.getAccessToken();
            Profile profile = Profile.getCurrentProfile();

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

                            try {
                                Name = object.getString("name");

                                FEmail = object.getString("email");
                                Log.v("Email = ", " " + FEmail);
                                Toast.makeText(getApplicationContext(), "Name " + Name, Toast.LENGTH_LONG).show();


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


        }

        @Override
        public void onCancel() {
            LoginManager.getInstance().logOut();

        }

        @Override
        public void onError(FacebookException e) {

        }
    };

Non otterrai il profilo che onSuccess()devi implementare ProfileTrackerinsieme alla registrazione della richiamata

mProfileTracker = new ProfileTracker() {
    @Override
    protected void onCurrentProfileChanged(Profile oldProfile, Profile newProfile) {
        // Fetch user details from New Profile
    }
};

Inoltre, non dimenticare di gestire l'inizio e l'arresto di tracker profilo

Ora avrai un profilo da cui ottenere AccessToken (risolto il problema del profilo null). Devi solo usare " https://developers.facebook.com/docs/android/graph#userdata " per ottenere qualsiasi dato.

Dopo il login

private void getFbInfo() {
    GraphRequest request = GraphRequest.newMeRequest(
            AccessToken.getCurrentAccessToken(),
            new GraphRequest.GraphJSONObjectCallback() {
                @Override
                public void onCompleted(
                        JSONObject object,
                        GraphResponse response) {
                    try {
                        Log.d(LOG_TAG, "fb json object: " + object);
                        Log.d(LOG_TAG, "fb graph response: " + response);

                        String id = object.getString("id");
                        String first_name = object.getString("first_name");
                        String last_name = object.getString("last_name");
                        String gender = object.getString("gender");
                        String birthday = object.getString("birthday");
                        String image_url = "http://graph.facebook.com/" + id + "/picture?type=large";

                        String email;
                        if (object.has("email")) {
                            email = object.getString("email");
                        }

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

È possibile utilizzare la classe GraphRequest per inviare chiamate all'API Graph di Facebook per ottenere informazioni sull'utente. Vedi https://developers.facebook.com/docs/android/graph per maggiori informazioni.

Questo ha funzionato per me, spero di aiutare qualcuno (usando il mio pulsante non il pulsante di accesso FB)

CallbackManager callbackManager;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    FacebookSdk.sdkInitialize(getApplicationContext());
    setContentView(R.layout.activity_sign_in_user);



     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) {
                    try {
                        Log.i("RESAULTS : ", object.getString("email"));
                    }catch (Exception e){

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

        }

        @Override
        public void onCancel() {

        }

        @Override
        public void onError(FacebookException error) {
            Log.i("RESAULTS : ", error.getMessage());
        }
    });


}

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


boolean isEmailValid(CharSequence email) {
    return android.util.Patterns.EMAIL_ADDRESS.matcher(email).matches();
}

public void signupwith_facebook(View view) {

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

Di seguito è riportato il codice per trovare l'ID e-mail, l'URL del nome e del profilo ecc

    private CallbackManager callbackManager;

    protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_sign_in);
//TODO on click of fb custom button call handleFBLogin()
     callbackManager = CallbackManager.Factory.create();
    }

    private void handleFBLogin() {
            AccessToken accessToken = AccessToken.getCurrentAccessToken();
            boolean isLoggedIn = accessToken != null && !accessToken.isExpired();

            if (isLoggedIn && Store.isUserExists(ActivitySignIn.this)) {
                goToHome();
                return;
            }

            LoginManager.getInstance().logInWithReadPermissions(ActivitySignIn.this, Arrays.asList("public_profile", "email"));
            LoginManager.getInstance().registerCallback(callbackManager,
                    new FacebookCallback<LoginResult>() {
                        @Override
                        public void onSuccess(final LoginResult loginResult) {
                            runOnUiThread(new Runnable() {
                                @Override
                                public void run() {
                                    setFacebookData(loginResult);
                                }
                            });
                        }

                        @Override
                        public void onCancel() {
                            Toast.makeText(ActivitySignIn.this, "CANCELED", Toast.LENGTH_SHORT).show();
                        }

                        @Override
                        public void onError(FacebookException exception) {
                            Toast.makeText(ActivitySignIn.this, "ERROR" + exception.toString(), Toast.LENGTH_SHORT).show();
                        }
                    });
        }

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 profileURL = "";
                            if (Profile.getCurrentProfile() != null) {
                                profileURL = ImageRequest.getProfilePictureUri(Profile.getCurrentProfile().getId(), 400, 400).toString();
                            }

                           //TODO put your code here
                        } catch (JSONException e) {
                            Toast.makeText(ActivitySignIn.this, R.string.error_occurred_try_again, Toast.LENGTH_SHORT).show();
                        }
                    }
                });
        Bundle parameters = new Bundle();
        parameters.putString("fields", "id,email,first_name,last_name");
        request.setParameters(parameters);
        request.executeAsync();
    }
      protected void onActivityResult(int requestCode, int resultCode, Intent data) {
            callbackManager.onActivityResult(requestCode, resultCode, data);
    }

Ecco una soluzione funzionante (2019): inserisci questo codice nella tua logica di accesso;

 GraphRequest request = GraphRequest.newMeRequest(loginResult.getAccessToken(), new GraphRequest.GraphJSONObjectCallback() {
                @Override
                public void onCompleted(JSONObject json, GraphResponse response) {
                    // Application code
                    if (response.getError() != null) {
                        System.out.println("ERROR");
                    } else {
                        System.out.println("Success");
                        String jsonresult = String.valueOf(json);
                        System.out.println("JSON Result" + jsonresult);

                        String fbUserId = json.optString("id");
                        String fbUserFirstName = json.optString("name");
                        String fbUserEmail = json.optString("email");
                        //String fbUserProfilePics = "http://graph.facebook.com/" + fbUserId + "/picture?type=large";
                        Log.d("SignUpActivity", "Email: " + fbUserEmail + "\nName: " + fbUserFirstName + "\nID: " + fbUserId);
                    }
                    Log.d("SignUpActivity", response.toString());
                }
            });
            Bundle parameters = new Bundle();
            parameters.putString("fields", "id,name,email,gender, birthday");
            request.setParameters(parameters);
            request.executeAsync();
        }

        @Override
        public void onCancel() {
            setResult(RESULT_CANCELED);
            Toast.makeText(SignUpActivity.this, "Login Attempt Cancelled", Toast.LENGTH_SHORT).show();
        }

        @Override
        public void onError(FacebookException error) {
            Toast.makeText(SignUpActivity.this, "An Error Occurred", Toast.LENGTH_LONG).show();
            error.printStackTrace();
        }
    });

Aggiungi questa linea su Fare clic sul pulsante

loginButton.setReadPermissions (Arrays.asList ("public_profile", "email", "user_birthday", "user_friends"));

Utilizzare il metodo statico FB getCurrentProfile () della classe Profile per recuperare tali informazioni.

 Profile profile = Profile.getCurrentProfile();
 String firstName = profile.getFirstName());
 System.out.println(profile.getProfilePictureUri(20,20));
 System.out.println(profile.getLinkUri());
