android - 使用 Android 版 Facebook 发送请求

Question

我正在使用适用于 Android 的 facebook sdk 3.0.1。我已按照教程进行操作，并且该应用程序运行良好。唯一的问题是，即使我的应用程序说请求已成功发送，也没有人收到我的请求。这是我的代码：

private void sendRequestDialog() {



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

    RequestsDialogBuilder requestsDialog = (new WebDialog.RequestsDialogBuilder(this,Session.getActiveSession(),params));
    requestsDialog.setOnCompleteListener(new OnCompleteListener() {

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

            })

   .build().show();
}'
