Question

我正在努力创建一个课程来处理我与Facebook的所有互动。我将我创建的Login活动传递给FacebookConnector对象（相关对象）以存储凭据等。请查看视频以查看我正在处理http://www.youtube.com/watch?v=OkHEy9Mh1hc的内容。以下是已删除App ID的FacebookConnector类

    catch(Exception e){
        showToast("Failed to post to wall. We fucked up :(");
        e.printStackTrace();
    }

    }

    @Override

        showToast("Authentification with Facebook failed!");        
    }

    @Override
    public void onCancel() {

    }

}

public void showToast(String message){
    Toast.makeText(activity.getApplicationContext(), message, Toast.LENGTH_SHORT).show();
}

}

我已清除浏览器缓存和应用数据。我已经检查了密钥哈希，并且已经多次将App ID复制并粘贴到应用程序中。

Answer 1

请确保您已将应用程序的签名添加到应用程序设置中，如下所示：

Answer 2

如果您尝试登录的Activity中没有onActivityResult()方法，登录将是Facebook，因为android sdk然后调用authorizeCallback(requestCode, resultCode, data)方法。

Facebook授权Android SDK失败
