代表用户从 Android 游戏在 Facebook 上自动 post

Question

我使用 Processing 为 android 开发了一款基于物理的 (Box2d) 游戏，我想为其添加分数共享选项，以便用户可以在他们的 Facebook 时间线上分享 his/her 最佳分数赛后。我在 Eclipse 中设置了 Facebook SDK。我在互联网上搜索并找到了这个解决方案：

public class FacebookConnector {
        private static final String APP_ID = "*************";
        private Facebook facebook;
        private AsyncFacebookRunner mAsyncRunner;
        String FILENAME = "AndroidSSO_data";
        SharedPreferences mPrefs;

        public FacebookConnector() {
            facebook = new Facebook(APP_ID);
            mAsyncRunner = new AsyncFacebookRunner(facebook);
        }

        public void loginToFacebook() {
            mPrefs = getPreferences(MODE_PRIVATE);
            String access_token = mPrefs.getString("access_token", null);
            long expires = mPrefs.getLong("access_expires", 0);

            if (access_token != null) {
                facebook.setAccessToken(access_token);
            }

            if (expires != 0) {
                facebook.setAccessExpires(expires);
            }

            if (!facebook.isSessionValid()) {
                facebook.authorize(LocalPakistaniGames.this,
                        new String[] { "email",
                        "publish_stream" }, new DialogListener() {

                    public void onCancel() {
                        // Function to handle cancel event
                    }

                    public void onComplete(Bundle values) {
                        // Function to handle complete event
                        // Edit Preferences and update facebook acess_token
                        SharedPreferences.Editor editor = mPrefs.edit();
                        editor.putString("access_token",
                                facebook.getAccessToken());
                        editor.putLong("access_expires",
                                facebook.getAccessExpires());
                        editor.commit();
                    }

                    public void onError(DialogError error) {
                        // Function to handle error

                    }

                    public void onFacebookError(FacebookError fberror) {
                        // Function to handle Facebook errors

                    }

                });
            }
        }

                        // User successfully Logged out

                            });
                }
            });
        }
    }

它工作正常，并提供了一个预填充的对话框，用户可以在其中共享或关闭对话框。我已经检查过它在 Facebook 时间线上正确共享。但问题是它没有使用设备上安装的 Facebook 应用程序。它在我的设备上使用 chrome 登录 Facebook。有没有办法强制它使用 Facebook 应用程序 android 而不是去 chrome （或任何其他浏览器）？？

Answer 1

你使用Facebook SDK有很多问题，但我会直接跳到你的问题。

您正在使用 "feed" 对话框进行共享。这是一个网络对话框，这就是它弹出 WebView（而不是实际的浏览器应用程序）的原因。您也不会将任何会话或访问令牌传递给提要对话框，这就是用户需要先登录才能共享的原因。

如果您想使用 Facebook 应用程序进行分享，我会推荐此文档：https://developers.facebook.com/docs/android/share

如果您想正确使用 Facebook SDK（而不是旧的已弃用的 SDK），请从这里开始：https://developers.facebook.com/docs/android/getting-started/

Answer 2

Here 是您问题的解决方案。如果你想在facebook wall 上自动发布，你必须使用graph api。此外，您要做的第一件事是使用 facebook 登录，然后，您必须再次请求权限。如果您使用 LoginManager:

LoginManager.getInstance().logInWithPublishPermissions(this, Arrays.asList("publish_actions"));

这行代码授予您的应用代表用户发布内容的权限
