发送Facebook好友通知

Question

我想向我选择的Facebook好友发送通知，根据该文档，我使用了以下代码。

private void sendNotification() {
        Bundle params = new Bundle();
        params.putString("href", "/testurl?param1=value1");
        params.putString("template", "This is a test message");
        /* make the API call */
        new Request(Session.getActiveSession(), "/me/notifications", params,
                HttpMethod.POST, new Request.Callback() {
                    public void onCompleted(Response response) {
                        /* handle the result */
                        Log.d(LOG_TAG, response.toString());
                    }
                }).executeAsync();
    }

我尝试了很多，发现facebook已经禁止在朋友墙上发帖，所以我可以选择发送通知，告知自己与所选朋友的活动。 这段代码对我不起作用。如果有人有解决方案请分享。我会非常感谢。谢谢

根据documentation -

  

目前，只有Facebook.com上的应用才能使用应用通知。通知仅显示在Facebook.com的桌面版本上。

因此，您必须在Facebook内部使用画布应用程序发送通知。

另外，还有其他不同的分享方式，请看一下这篇文章：Sharing in Android

修改

实施/feed API -

private void publishStory() {
Session session = Session.getActiveSession();

if (session != null){

    // Check for publish permissions    
    List<String> permissions = session.getPermissions();
    if (!isSubsetOf(PERMISSIONS, permissions)) {
        pendingPublishReauthorization = true;
        Session.NewPermissionsRequest newPermissionsRequest = new Session
                .NewPermissionsRequest(this, PERMISSIONS);
    session.requestNewPublishPermissions(newPermissionsRequest);
        return;
    }

    Bundle postParams = new Bundle();
    postParams.putString("name", "Facebook SDK for Android");
    postParams.putString("caption", "Build great social apps and get more installs.");
    postParams.putString("description", "The Facebook SDK for Android makes it easier and faster to develop Facebook integrated Android apps.");
    postParams.putString("link", "https://developers.facebook.com/android");
    postParams.putString("picture", "https://raw.github.com/fbsamples/ios-3.x-howtos/master/Images/iossdk_logo.png");

    Request.Callback callback= new Request.Callback() {
        public void onCompleted(Response response) {
            JSONObject graphResponse = response
                                       .getGraphObject()
                                       .getInnerJSONObject();
            String postId = null;
            try {
                postId = graphResponse.getString("id");
            } catch (JSONException e) {
                Log.i(TAG,
                    "JSON error "+ e.getMessage());
            }
            FacebookRequestError error = response.getError();
            if (error != null) {
                Toast.makeText(getActivity()
                     .getApplicationContext(),
                     error.getErrorMessage(),
                     Toast.LENGTH_SHORT).show();
                } else {
                    Toast.makeText(getActivity()
                         .getApplicationContext(), 
                         postId,
                         Toast.LENGTH_LONG).show();
            }
        }
    };

    Request request = new Request(session, "me/feed", postParams, 
                          HttpMethod.POST, callback);

    RequestAsyncTask task = new RequestAsyncTask(request);
    task.execute();
}
}
