Send Facebook friends notification

Question

I want to send notification to my selected Facebook friends,According to the doc,I used following code.

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();
    }

I tried lot and found that facebook has blocked permission to post on friends wall so I have option to send notification to inform own activity with selected friends. This code is not working for me.If any one has solution please share.I will really appreciate this.Thanks

According to documentation-

Currently, only apps on Facebook.com can use App Notifications. Notifications are only surfaced on the desktop version of Facebook.com.

So you have to have a canvas app inside facebook to send the notification.

Else, there are other different ways of sharing, have a look at this article: Sharing in Android

Edit:

Implementing /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();
}
}
