Facebook API读取和发布

Question

我需要授予用户对身份验证的读取和发布权限。发布用于发布他们的分数，也保存在Facebook上。我使用以下代码段进行身份验证。

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

        }
        @Override
        public void onError(FacebookException e) {      }
    };

   @Override
    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_login);

        backtogame = (Button) findViewById(R.id.backtogame);
        backtogame.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                finish();
            }
        });

        loginButton = (LoginButton) findViewById(R.id.login_button);
        loginButton.setLoginBehavior(LoginBehavior.WEB_ONLY);



           // if (isLoggedIn()) {
               // Profile profile = Profile.getCurrentProfile();
                //nextActivity(profile);
           // }

            FacebookSdk.sdkInitialize(getApplicationContext());

            callbackManager = CallbackManager.Factory.create();
            accessTokenTracker = new AccessTokenTracker() {
                @Override
                protected void onCurrentAccessTokenChanged(AccessToken oldToken, AccessToken newToken) {
                }
            };

            profileTracker = new ProfileTracker() {
                @Override
                protected void onCurrentProfileChanged(Profile oldProfile, Profile newProfile) {
                    nextActivity(newProfile);
                }
            };

            accessTokenTracker.startTracking();
            profileTracker.startTracking();

            callback = new FacebookCallback<LoginResult>() {

                @Override
                public void onSuccess(LoginResult loginResult) {
                    AccessToken accessToken = loginResult.getAccessToken();
                    Profile profile = Profile.getCurrentProfile();
                    nextActivity(profile);
                }



                @Override
                public void onCancel() {
                    Toast.makeText(LoginActivity.this, "Canceled!", Toast.LENGTH_SHORT).show();

                }

                @Override
                public void onError(FacebookException e) {
                    Toast.makeText(LoginActivity.this, "Error, Check your internet connection!", Toast.LENGTH_SHORT).show();
                }
            };


                loginButton.setReadPermissions("public_profile", "user_friends", "user_games_activity");
                loginButton.registerCallback(callbackManager, callback);
        }



    @Override
    protected void onResume() {
        super.onResume();
        //Facebook login

            Profile profile = Profile.getCurrentProfile();

            // loginButton.clearPermissions();
            // loginButton.setPublishPermissions("publish_actions");   //write permissions should be set after read permission, and need to change category on facebook to game
            nextActivity(profile);


    }

    @Override
    protected void onPause() {

        super.onPause();
    }

    protected void onStop() {
        super.onStop();
        //Facebook login
            accessTokenTracker.stopTracking();
            profileTracker.stopTracking();
    }



    @Override
    protected void onActivityResult(int requestCode, int responseCode, Intent intent) {
        super.onActivityResult(requestCode, responseCode, intent);
        //Facebook login
        LoginManager.getInstance().logOut();
        callbackManager.onActivityResult(requestCode, responseCode, intent);
    }

如果我添加＆＃34; publish_actions＆＃34;对loginbutton的权限，它将不再要求读取权限。

我在网上发现的所有文章都与会话参数有关，而该会话参数已不再使用。
