Facebook好友请求不发送

Question

我在我的应用中遇到了Facebook集成问题。我实现了连接，它就像一个魅力，当我尝试向朋友发送请求时，通知不会显示在朋友的Facebook应用程序（或网站）中。我已按照本教程实施请求：https://developers.facebook.com/docs/android/send-requests/

我检查了我的哈希键，看起来是正确的。我已将android debug.keystore哈希键放在开发人员设置和应用程序哈希键中。我还禁用了沙箱模式并提供了正确的包名和类名。我到处寻找，似乎无法找到解决方案。

如果有人知道我的问题是什么，那就太棒了:)。

这是我的代码：

private void sendRequestDialog() {
    Bundle params = new Bundle();
    params.putString("message",
            "Learn how to make your Android apps social");

    final Session session = Session.openActiveSessionFromCache(mContext);

    WebDialog requestsDialog = (new WebDialog.RequestsDialogBuilder(
            mContext, session, params)).setOnCompleteListener(
            new OnCompleteListener() {

                @Override
                public void onComplete(Bundle values,
                        FacebookException error) {
                    if (error != null) {
                        if (error instanceof FacebookOperationCanceledException) {
                            Toast.makeText(mContext, R.id.request_cancelled,
                                    Toast.LENGTH_SHORT).show();
                        } else {
                            Toast.makeText(mContext, R.id.network_error,
                                    Toast.LENGTH_SHORT).show();
                        }
                    } else {
                        final String requestId = values
                                .getString("request");
                        if (requestId != null) {
                                sendRequest(friend_facebook_id, session);
                        } else {
                            Toast.makeText(mContext, R.id.request_cancelled,
                                    Toast.LENGTH_SHORT).show();
                        }
                    }
                }

            }).build();
    requestsDialog.show();



}

protected void sendRequest(String friend_facebook_id, Session session) {
    Bundle params = new Bundle();
    params.putString("message",
            "Learn how to make your Android apps social");
    params.putString("to", friend_facebook_id);

    WebDialog requestsDialog = (new WebDialog.RequestsDialogBuilder(
            mContext, session, params)).setOnCompleteListener(
            new OnCompleteListener() {

                @Override
                public void onComplete(Bundle values,
                        FacebookException error) {
                    if (error != null) {
                        if (error instanceof FacebookOperationCanceledException) {
                            Toast.makeText(mContext, "Request cancelled",
                                    Toast.LENGTH_SHORT).show();
                        } else {
                            Toast.makeText(mContext, "Network Error",
                                    Toast.LENGTH_SHORT).show();
                        }
                    } else {
                        final String requestId = values
                                .getString("request");
                        if (requestId != null) {
                            Toast.makeText(mContext, "Request sent",
                                    Toast.LENGTH_SHORT).show();
                        } else {
                            Toast.makeText(mContext, "Request cancelled",
                                    Toast.LENGTH_SHORT).show();
                        }
                    }
                }

            }).build();
    requestsDialog.show();
}
