如何在Android上使用Facebook SDK 3.0发布消息和图片

链接 - ＆gt;可以发布带有链接和所有其他信息的小图片。

http://developers.facebook.com/docs/howtos/androidsdk/3.0/feed-dialog/

我想要的只是在墙上发布带有消息的Pic，而不是带描述的链接？，我需要在自定义按钮点击时发布消息。

private void publishStory() {


        Session session = Session.getActiveSession();

        if (session != null){


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



            FileInputStream fis = null;
            try {

                fis = new FileInputStream(imagepath);

            } catch (FileNotFoundException e1) {

                e1.printStackTrace();
            }

            Bitmap b = BitmapFactory.decodeStream(fis);
             ByteArrayOutputStream stream = new ByteArrayOutputStream();
              b.compress(Bitmap.CompressFormat.JPEG, 100, stream);
              byte[] byteArray = stream.toByteArray();



            Bundle postParams = new Bundle();
            postParams.putString("message", "Facebook SDK for Android ");

              postParams.putByteArray("source",byteArray);

            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("JSON error ","JSON error "+ e.getMessage());
                    }
                    FacebookRequestError error = response.getError();

                    if (error != null) {

                        Toast.makeText(getApplicationContext(),error.getErrorMessage(),Toast.LENGTH_SHORT).show();

                    } else {

                        Toast.makeText(getApplicationContext(), postId,Toast.LENGTH_LONG).show();

                    }
                }
            };

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

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

    }
