我使用以下代码在我的应用中通过Facebook登录。我需要通过Facebook SSO做到这一点。我有正确的app_id。

                mFacebook.authorize(this, new DialogListener() {

                    @Override

                AsyncFacebookRunner asyncRunner = new AsyncFacebookRunner(mFacebook);
                 asyncRunner.logout(this.getBaseContext(), new  LogoutRequestListener());
            }

            break;


        default:
            return false;

        }
        return true;
    }

    }

我在设备中登录了预装的Facebook应用。而且我只有这个屏幕。 enter image description here

在我的Logcat中出现了这一行。

09-28 15:18:24.652: E/ActivityThread(1201): Failed to find provider info for com.facebook.katana.provider.AttributionIdProvider

如果我从预装的Facebook应用程序退出，我的应用程序会提示我登录，询问凭据。那个时候，空屏幕出现了。但是在预装的Facebook应用程序中，我可以看到我的更新。（我登录）。

更新

现在我只检查应用程序。我还没有把它发布到市场上。我通过引用此网站获得了密钥http://sean.lyn.ch/2011/07/android-the-facebook-sdk-sso-and-you/。我把它添加到应用程序中，就像这样。 enter image description here

更新2：现在我在logcat中获得了这些行：

09-29 12:00:12.552: I/ActivityManager(73): Starting activity: Intent { cmp=com.facebook.katana/.ProxyAuth (has extras) }
09-29 12:00:13.022: I/ActivityManager(73): Displayed activity com.facebook.katana/.ProxyAuth: 436 ms (total 436 ms)
09-29 12:00:15.032: W/InputManagerService(73): Starting input on non-focused client com.android.internal.view.IInputMethodClient$Stub$Proxy@434b2e88 (uid=10031 pid=2233)
09-29 12:00:15.032: W/IInputConnectionWrapper(2233): showStatusIcon on inactive InputConnection

Answer 1

由于以下原因，可能会发生这种情况：

您未连接到互联网
您尚未获得互联网访问权限（Manifest.xml）
您没有为应用程序使用正确的哈希键
您未提供正确的应用ID

Facebook SSO不在android中工作
