Facebook SDK v3.0 请求对话框不发送应用程序请求

Question

我正在使用适用于 Facebook 的 Android SDK v3.0 向朋友发送使用我的应用程序的请求。我使用在here 上看到的代码打开 Facebook 的 Dialog 应用并向用户的朋友发出请求。

使用以下代码显示并发送请求后。我现在收到“请求已发送”toast，但从未发送过请求。

private void sendRequestDialog() {
    Bundle params = new Bundle();
    params.putString("message", "MESSAGE");
    params.putString("app_id", "APPID");

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

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

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

Request Dialog显示过程中从Logcat获取如下日志：

请指点我正确的方向...

在 facebook 开发者帐户的应用程序设置中添加一个画布框架，然后添加以下代码以发送应用程序请求。 如果在活动中将 getActivity() 替换为 YourActivityName.this 如果在片段中不需要替换任何东西

Bundle params = new Bundle();
            params.putString("message",
                    "Join CConnect To feel Better Experience Of Meetings And Calls");

            WebDialog requestsDialog = (new WebDialog.RequestsDialogBuilder(
                    getActivity(), Session.getActiveSession(), params))
                    .setTheme(
                            android.R.style.Theme_Translucent_NoTitleBar_Fullscreen))
                    .setOnCompleteListener(new OnCompleteListener() {

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

                                                    .getApplicationContext(),
                                            "Request cancelled",
                                            Toast.LENGTH_SHORT).show();
                                }
                            }
                        }

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