Question

我在Android应用中使用Facebook登录。我已成功登录Facebook，但我没有得到特定用户的提要。即该用户在Facebook上发布的帖子。

我试过的就像下面......

                            }
                        });
    }

    void callWatsonAPI(String social) {
        PersonalityInsights service = new PersonalityInsights();
        service.setUsernameAndPassword("27324e40-6c74-44f0-a3b9-9659cf5b4ed5", "eGXEQ8EGpVTl");
        service.setEndPoint("https://gateway.watsonplatform.net/personality-insights/api");
        Profile profile = service.getProfile(social_feed);

        /*Log.e("Watson Response: ", "" + profile);*/

        if (social.equals("fb")) {
            Intent intent = new Intent(getApplicationContext(), SecondActivity.class);
            intent.putExtra("watson_res", profile.toString());
            intent.putExtra("Fb Feed", social_feed);
            startActivity(intent);
        } else {
            Intent intent = new Intent(getApplicationContext(), SecondActivity.class);
            intent.putExtra("watson_res", profile.toString());
            intent.putExtra("Twitter Feed", social_feed);
            startActivity(intent);
        }
    }
}

我获得了一个特定Facebook帐户的无效JSON响应。在那个帐户中，我已将安全性设置为公开。但对于我个人的Facebook帐户，我得到{"data":[]}。即回应无效。

我在build.gradle文件中使用了compile 'com.facebook.android:facebook-android-sdk:4.10.0'依赖项。

提前致谢。

我从Facebook找到了这些信息。我所做的就像下面一样。

当您的应用处于开发者模式时，Facebook会提供添加测试人员帐户的选项，您可以通过该帐户测试Facebook的不同功能。下面两张图片可以为您提供更好的 IDEA 。看一看。

希望这会对某人有所帮助。

没有使用Facebook SDK 4.10.0 Android获取用户Facebook Feed
